This book is valuable for researchers or students working on medicinal plants, phytochemistry, and plant tissue culture. It also serves as a reference for the pharmaceutical industry.

Sustainable increase in agricultural production while keeping the environmental quality, agro-ecosystem function and biodiversity is a real challenge in current agricultural practices. Application of PGPR can help in meeting the expected demand for increasing agricultural productivity to feed the world's booming population. Global concern over the demerits of chemicals in agriculture has diverted the attention of researchers towards sustainable agriculture by utilizing the potential of Plant Growth Promoting Rhizobacteria (PGPR). Use of PGPR as biofertilizers, biopesticides, soil, and plant health managers has gained considerable agricultural and commercial significance. The book Plant Growth Promoting Rhizobacteria (PGPR): Prospects for Sustainable Agriculture has contributions in the form of book chapter from 25 eminent global researchers, that discusses about the PGPRs and their role in growth promotion of various crop plants, suppression of wide range of phytopathogens, their formulation, effect of various factors on growth and performance of PGPR, assessment of diversity of PGPR through microsatellites and role of PGPR in mitigating biotic and abiotic stress.This book will be helpful for students, teachers, researchers, and entrepreneurs involved in PGPR and allied fields. The book will be highly useful to researchers, teachers, students, entrepreneurs, and policymakers.

This book presents recent advances in global wheat crop research, including the effects of abiotic stresses like high and low temperatures, drought, hypoxia, salinity, heavy metals, nutrient deficiency, and toxicity on wheat production. It also highlights various approaches to alleviate the damaging effects of abiotic stress on wheat as well as advanced approaches to develop abiotic-stress-tolerant wheat crops. Wheat is probably one of the world's most important cereals; it is a staple food in more than 40 countries, and because of its adaptability is cultivated in almost every region. Global wheat production has more than doubled in the last 50 years due to higher yields. However, despite their high yield potential, modern wheat cultivars are often subject to crop loss due to the abiotic stresses. As such, plant breeders have long aimed to improve tolerance in order to maintain yield. Written by 85 experts, and offering the latest insights into wheat responses and tolerance to various abiotic stresses, it is a valuable tool for agronomists, plant breeders, plant physiologists and students in the field of plant science and agriculture. It is the first book to comprehensively cover past and current abiotic stress problems and tolerance mechanisms.

This book highlights the advances in essential oil research, from the plant physiology perspective to large-scale production, including bioanalytical methods and industrial applications. The book is divided into 4 sections. The first one is focused on essential oil composition and why plants produce these compounds that have been used by humans since ancient times. Part 2 presents an update on the use of essential oils in various areas, including food and pharma industries as well as agriculture. In part 3 readers will find new trends in bioanalytical methods. Lastly, part 4 presents a number of approaches to increase essential oil production, such as in vitro and hairy root culture, metabolic engineering and biotechnology. Altogether, this volume offers a comprehensive look at what researchers have been doing over the last years to better understand these compounds and how to explore them for the benefit of the society.

With the recent shift of chemical fertilizers and pesticides to organic agriculture, the employment of microbes that perform significant beneficial functions for plants has been highlighted. This book presents timely discussion and coverage on the use of microbial formulations, which range from powdered or charcoal-based to solution and secondary metabolite-based bioformulations. Bioformulation development of biofertilizers and biopesticides coupled with the advantages of nanobiotechnology propose significant applications in the agricultural section including nanobiosensors, nanoherbicides, and smart transport systems for the regulated release of agrochemical. Moreover, the formulation of secondary metabolites against individual phytopathogens could be used irrespective of geographical positions with higher disease incidences. The prospective advantages and uses of nanobiotechnology generate tremendous interest, as it could augment production of agricultural produce while being cost-effective both energetically and economically. This bioformulation approach is incomparable to existing technology, as the bioformulation would explicitly target the particular pathogen without harming the natural microbiome of the ecosystem. Nanobiotechnology in Bioformulations covers the constraints associated with large-scale development and commercialization of bioinoculant formations. Furthermore, exclusive emphasis is be placed on next-generation efficient bioinoculants having secondary metabolite formulations with longer shelf life and advanced competence against several phytopathogens. Valuable chapters deal with bioformulation strategies that use divergent groups of the microbiome and include detailed diagrammatic and pictorial representation. This book will be highly beneficial for both experts and novices in the fields of microbial bioformulation, nanotechnology, and nano-microbiotechnology. It discusses the prevailing status and applications available for microbial researchers and scientists, agronomists, students, environmentalists, agriculturists, and agribusiness professionals, as well as to anyone devoted to sustaining the ecosystem.

The third edition of "Seeds: The Ecology of Regeneration in Plant Communities" highlights the many advances in the field of seed ecology and its relationship to plant community dynamics that have taken place in recent years. The new edition also features chapters on seed development and morphology, seed chemical ecology, implications of climate change on regeneration by seed, and the functional role of seed banks in agricultural and natural ecosystems. The book is aimed at advanced level students and researchers in the fields of seed science, seed ecology and plant ecology.

This book discusses the role of salt in current agricultural approaches, including the low salt tolerance of agricultural crops and trees, impact of saline soils, and salt-resistant plants. Halophytes are extremely salt tolerant plants, which are able to grow and survive under salt at concentrations as high as 5 g/l by maintaining negative water potential. The salt-tolerant microbes inhabiting the rhizospheres of halophytes may contribute to their salt tolerance, and the rhizospheres of halophytic plants provide an ideal opportunity for isolating various groups of salt-tolerant microbes that could enhance the growth of different crops under salinity stress. The book offers an overview of salt-tolerant microbes' ability to increase plant tolerance to salt to facilitate plant growth, the potential of the halophytes' rhizospheres as a reservoir of beneficial salt-tolerant microbes, their future application as bio-inoculants in agriculture and a valuable resource for an alternative way of improving crop tolerance to salinity and promoting saline soil-based agriculture. This special collection of reviews highlights some of the recent advances in applied aspects of plant (halophytes)-microbe interactions and their contribution towards eco-friendly approaches saline soil-based agriculture.

Dothistroma pini changed New Zealand commercial forestry dramatically. Tree breeding became concentrated on a very few species and development of selection methods and breeding strategies changed in response to the new challenges. Tree-Breeding and Genetics in New Zealand provides a critical historical account of the work on provenance research and tree breeding, often with the wisdom of hindsight, and it tracks the development of breeding strategy, especially for P. radiata, Douglas-fir and the most important eucalypt species, E. regnans, E. fastigata and E. nitens. The book is a compendium of abstracts and summaries of all publications and reports on tree improvement in New Zealand since the early 1950s, with added critical comment by the author on much of the work. It is intended for other tree breeders internationally, for interested NZ foresters and for graduate students studying genetics and tree breeding.

The grasses and legumes grown in pastures and rangelands form the basis of the worldwide animal production industry. Some species also have a significant role in the sport and leisure industry, for playing surfaces such as golf courses and football fields. It is therefore vitally important to ensure that seed supplies of appropriate species are available for use on a commercial scale. This book is published in association with the International Herbage Seed Production Research Group. It brings together leading researchers and along with its companion volume Forage Seed Production Volume 2: Tropical and Subtropical Species (to be published in late 1998), provides the definitive resource for all those concerned with breeding and profitable seed production for grasses and legumes used within grazing systems or recreation and amenity provision. The book is in two parts. Part 1 covers all aspects relevant to seed production, including improving seed yield and quality, crop management, harvesting, processing and the international seed trade. Part 2 consists of eleven case studies from eight countries covering three continents. This book and its companion should be read by all seed scientists involved in the breeding and commercial production of grass and legume seed. They also represent a valuable asset for all commercial seed suppliers. Additionally, the information presented within the book is important for all students and lecturers within departments of agriculture and plant breeding.

Plant Adaptation and Crop Improvement focuses on the opportunities for increasing the efficiency of crop improvement by understanding the basis of variation for plant adaptation in agricultural production systems. Crop improvement strategies based on combinations of the statistical modelling methodologies used by plant breeders and the crop modelling methodologies used by crop physiologists/agronomists are developed and discussed. The book captures much of the experience of scientists from around the world who have worked on the challenging problem of achieving crop improvement in variable crop production systems. It represents a major synthesis for workers in plant breeding, crop physiology and agronomy.

Soil salinity is a key abiotic-stress and poses serious threats to crop yields and quality of produce. Owing to the underlying complexity, conventional breeding programs have met with limited success. Even genetic engineering approaches, via transferring/overexpressing a single 'direct action gene' per event did not yield optimal results. Nevertheless, the biotechnological advents in last decade coupled with the availability of genomic sequences of major crops and model plants have opened new vistas for understanding salinity-responses and improving salinity tolerance in important glycophytic crops. Our goal is to summarize these findings for those who wish to understand and target the molecular mechanisms for producing salt-tolerant and high-yielding crops. Through this 2-volume book series, we critically assess the potential venues for imparting salt stress tolerance to major crops in the post-genomic era. Accordingly, perspectives on improving crop salinity tolerance by targeting the sensory, ion-transport and signaling mechanisms were presented in Volume 1. Volume 2 now focuses on the potency of post-genomic era tools that include RNAi, genomic intervention, genome editing and systems biology approaches for producing salt tolerant crops.

In horticulture, agriculture, and food science, plants' reproductive physiology is an important topic relating to fruits and vegetables, the main consumable parts of plants. All aspects of plant physiology, including plants' reproductive systems, are important to the production of food, fibers, medicine, cosmetics, and even fuels. This volume presents many new studies on plants' reproductive systems, including new research on sperm cells in plant reproduction; the effect of herbivory on plant reproduction; disturbances to functional diversity; plant genes, hormones, DNA; and much more.

Reproduction is a fundamental feature of life, it is the way life persists across the ages. This book offers new, wider vistas on this fundamental biological phenomenon, exploring how it works through the whole tree of life. It explores facets such as asexual reproduction, parthenogenesis, sex determination and reproductive investment, with a taxonomic coverage extended over all the main groups - animals, plants including 'algae', fungi, protists and bacteria. It collates into one volume perspectives from varied disciplines - including zoology, botany, microbiology, genetics, cell biology, developmental biology, evolutionary biology, animal and plant physiology, and ethology - integrating information into a common language. Crucially, the book aims to identify the commonalties among reproductive phenomena, while demonstrating the diversity even amongst closely related taxa. Its integrated approach makes this a valuable reference book for students and researchers, as well as an effective entry point for deeper study on specific topics.

This volume will be the only existing single-authored book offering a science-based breeder's manual directed at breeding for water-limited environments. Plant breeding is characterized by the need to integrate information from diverse disciplines towards the development and delivery of a product defines as a new cultivar. Conventional breeding draws information from disciplines such as genetics, plant physiology, plant pathology, entomology, food technology and statistics. Plant breeding for water-limited environments and the development of drought resistant crop cultivars is considered as one of the more difficult areas in plant breeding while at the same time it is becoming a very pressing issue. This volume is unique and timely in that it develops realistic solutions and protocols towards the breeding of drought resistant cultivars by integrating knowledge from environmental science, plant physiology, genetics and molecular biology.

Pigeonpea (Cajanus cajan) is a crop of small land holding farmers in arid and semi-arid regions of the world. It has a number of usages starting from protein rich food to vegetarian families; fuel wood; nitrogen supplier to soil; recycling minerals in soil to animal feed etc. Pigeonpea has been considered to be originated and domesticated in central India from where it travelled to different parts of the world such as Africa and Latin America. In ongoing scenario of climate change, biotic and especially abiotic stresses will make the conditions more challenging for entire agriculture. This volume focusing on the pigeonpea genome will collate the information on the genome sequencing and its utilization in genomics activities, with a focus on the current findings, advanced tools and strategies deployed in pigeonpea genome sequencing and analysis, and how this information is leading to direct outcomes for plant breeders and subsequently to farmers.

This book presents the current state of the art in peanut genomics, focusing particularly on the latest genomic findings, tools and strategies employed in genome sequencing, transcriptomes and analysis, availability of public and private genomic resources, and ways to maximize the use of this information in peanut breeding programs. Further, it demonstrates how advances in plant genomics can be used to improve crop breeding. The peanut or groundnut (Arachis hypogaea L. Millsp) is a globally important grain legume and oilseed crop, cultivated in over 100 countries and consumed in the form of roasted seeds, oil and confectionary in nearly every country on Earth. The peanut contributes towards achieving food and nutritional security, in addition to financial security through income generation; as such, it is also vital to the livelihood of the poor in the developing world. There have been significant advances in peanut research, especially in the last five years, including sequencing the genome of both diploid progenitors, and the availability of tremendous transcriptome resources, large-scale genomic variations that can be used as genetic markers, genetic populations (bi- and multiparent populations and germplasm sets), marker-trait associations and molecular breeding products. The immediate availability of the genome sequence for tetraploid cultivated peanuts is the most essential genomic resource for achieving a deeper understanding of peanut traits and their use in breeding programs.

In nature, radiata pine is very localised and an obscure tree species despite the romantic character of much of its natural habitat. That obscure status and the lack of any reputation as a virgin timber slowed its due recognition as a commercial crop. Nevertheless, it has become a major plantation forest crop internationally. It has become the pre-eminent commercial forest species in New Zealand, Chile and Australia, with important plantings in some other countries. It consequently features prominently in the international trade in forest products, in addition to its importance in domestic markets of grower countries. Very fast growth, considerable site tolerances, ease of raising in nurseries and transplanting, and ease of processing and using its wood for a range of products and purposes, have made it the utility softwood of choice almost everywhere it can be grown satisfactorily. Abundant genetic variation and its amenability to other management inputs created special opportunities for its domestication. The story of its domestication forms a classic case history in the development of modern commercial forestry, with trailblazing in both genetic improvement and plantation management; this inevitably meant a learning process that provided instructive lessons, especially for tree breeders dealing with some other species. Paradoxically, the plantation monocultures have played and can continue to play an important role in protecting natural forests and other forms of biodiversity. Given the attractions of growing radiata pine, there were inevitably cases of overreach in planting it, with lessons to be learnt. Economic globalisation has meant globalisation of pests and disease organisms, and the scale on which radiata pine is grown has meant is has been the focus of various biotic alarms, none of which have proved catastrophic. Temptations, remain, however, to pay less than due attention to some aspects of risk management. The chapter structure of the book is based on historical periods, beginning long before any important human influences, and ending with a look into what the future might hold for the species and its role in human and ecological sustainability. Almost throughout, there has been complex interplay between the technical aspects, local social and economic factors, various types of institution, the enthusiasm and drive of some very influential individuals, and tides of economic ideology, threads that needed to be woven together to do the story justice.

This book sheds new light on the chickpea genome sequencing and resequencing of chickpea germplasm lines and provides insights into classical genetics, cytogenetics, and trait mapping. It also offers an overview of the latest advances in genome sequencing and analysis. The growing human population, rapid climate changes and limited amounts of arable land are creating substantial challenges in connection with the availability and affordability of nutritious food for smallholder farmers in developing countries. In this context, climate smart crops are essential to alleviating the hunger of the millions of poor and undernourished people living in developing countries. In addition to cereals, grain legumes are an integral part of the human diet and provide sustainable income for smallholder farmers in the arid and semi-arid regions of the world. Among grain legumes, the chickpea (Cicer arietinum) is the second most important in terms of production and productivity. Besides being a rich source of proteins, it can fix atmospheric nitrogen through symbiosis with rhizobia and increase the input of combined nitrogen. Several abiotic stresses like drought, heat, salinity, together with biotic stresses like Fusarium wilt, Ascochyta blight, and Botrytis grey mould have led to production losses, as the chickpeas is typically grown in the harsh climates of our planet's semi-arid regions.

This book provides insights into the genetics and the latest advances in genomics research on the common bean, offering a timely overview of topics that are pertinent for future developments in legume genomics. The common bean (Phaseolus vulgaris L.) is the most important grain legume crop for food consumption worldwide, as well as a model for legume research, and the availability of the genome sequence has completely changed the paradigm of the ongoing research on the species. Key topics covered include the numerous genetic and genomic resources, available tools, the identified genes and quantitative trait locus (QTL) identified, and there is a particular emphasis on domestication. It is a valuable resource for students and researchers interested in the genetics and genomics of the common bean and legumes in general.

Bioremediation is the use of microorganisms' metabolism to degrade waste contaminants (sewage, domestic, and industrial effluents) into non-toxic or less toxic materials by natural biological processes. Remediation through fungi-or mycoremediation-has multifarious possibilities in applied remediation engineering and the future of environmental sustainability. Fungi have the biochemical and ecological capability to degrade environmental organic chemicals and to decrease the risk associated with metals, semi-metals, noble metals, and radionuclides, either by chemical modification or by manipulating chemical bioavailability. Additionally, the capability of these fungi to form extended mycelia networks, the low specificity of their catabolic enzymes, and their using pollutants as a growth substrate make these fungi well suited for bioremediation processes. Their mycelia exhibit the robustness of adapting to highly limiting environmental conditions often experienced in the presence of persistent pollutants, which makes them more useful compared to other microbes. However, despite dominating the living biomass in soil and being abundant in aquatic ecosystems, fungi have not been exploited for the bioremediation of such environments. This book covers the various types of fungi and associated fungal processes used to clean up waste and wastewaters in contaminated environments and discusses future potential applications.

Meeting the world's food security challenge will require a multi-national, collaborative effort to integrate the best research from science, engineering and socioeconomics so that technological advances can bring benefits where they are most needed. The present book covers the effect of major environmental problems on crop production and how to cope with these issues for sustainable agriculture and improvements of crops. The world's population is predicted to hit 9.6 Billion by 2050, up from today's total of nearly 7.3 Billion, and with it food demand is predicted to increase substantially. The post-war 'second agricultural revolution' in developed countries, and the 'green revolution' in developing nations in the mid- 1960s converted agricultural practices and elevated crop yields spectacularly, but the outcome is levelling off and will not meet projected demand. Simultaneously, crop production is affected by many other factors, including industrial pollution, overuse of fertilizers and insecticides, heavy metal and radiation stresses etc. It has been noted that many pests are becoming resistant to insecticides. Estimates vary, but around 25% of crops can be lost to pests and diseases. Climate change associated with agriculture is also a global issue. Agriculture is a significant contributor to greenhouse gases and is estimated to account for 10-12% of total greenhouse gas (GHG) emissions. Many of the issues highlighted are global problems and are addressed thoroug hly in this work.

This book places grapes in the context of their family, the Vitaceae. It begins by focusing on the relationship of the family to other angiosperms and the interrelationships and characteristics of its genera. Two chapters emphasize the structure and development of its major vegetative and reproductive characteristics. Keys and illustrated descriptions for 19 North American species including 10 Vitis are provided. The three chapters on Vitis begin with a brief history of grape growing, with emphasis on North America. There is an illustrated life history of grape, following the two-year cycle from bud initiation to fruit maturity. The final chapter discusses the history of grapevine identification in North America, concluding with descriptions and illustrations of 30 important North American cold climate cultivars. The book is a general resource for understanding the growth, development, life history, and identification of grapes and the Vitaceae.

Bioremediation is the use of microorganisms' metabolism to degrade waste contaminants (sewage, domestic, and industrial effluents) into non-toxic or less toxic materials by natural biological processes. Volume 2 offers new discussion of remediation through fungi-or mycoremediation-and its multifarious possibilities in applied remediation engineering and the future of environmental sustainability. Fungi have the biochemical and ecological capability to degrade environmental organic chemicals and to decrease the risk associated with metals, semi-metals, noble metals, and radionuclides, either by chemical modification or by manipulating chemical bioavailability. Additional expanded texts shows the capability of these fungi to form extended mycelia networks, the low specificity of their catabolic enzymes, and their use against pollutants as a growth substrate, making these fungi well suited for bioremediation processes. Their mycelia exhibit the robustness of adapting to highly limiting environmental conditions often experienced in the presence of persistent pollutants, which makes them more useful compared to other microbes. Despite dominating the living biomass in soil and being abundant in aquatic ecosystems, however, fungi have not been exploited for the bioremediation of such environments until this added Volume 2. This book covers the various types of fungi and associated fungal processes used to clean up waste and wastewaters in contaminated environments and discusses future potential applications.

During the past 15 years, cellular and molecular approaches have emerged as valuable adjuncts to supplement and complement conventional breeding methods for a wide variety of crop plants. Biotechnology increasingly plays a role in the creation, conservation, characterization and utilization of genetic variability for germplasm enhancement. For instance, anther/microspore culture, somaclonal variation, embryo culture and somatic hybridization are being exploited for obtaining incremental improvement in the existing cultivars. In addition, genes that confer insect- and disease-resistance, abiotic stress tolerance, herbicide tolerance and quality traits have been isolated and re-introduced into otherwise sensitive or susceptible species by a variety of transgenic techniques. Together these transformative methodologies grant access to a greater repertoire of genetic diversity as the gene(s) may come from viruses, bacteria, fungi, insects, animals, human beings, unrelated plants or even be artificially derived. Remarkable achievements have been made in the production, characterization, field evaluation and commercialization of transgenic crop varieties worldwide. Likewise, significant advances have been made towards increasing crop yields, improving nutritional quality, enabling crops to be raised under adverse conditions and developing resistance to pests and diseases for sustaining global food and nutritional security. The overarching purpose of this 3-volume work is to summarize the history of crop improvement from a technological perspective but to do so with a forward outlook on further advancement and adaptability to a changing world. Our carefully chosen "case studies of important plant crops" intend to serve a diverse spectrum of audience looking for the right tools to tackle complicated local and global issues.

This book presents an overview of the state-of-the-art in barley genome analysis, covering all aspects of sequencing the genome and translating this important information into new knowledge in basic and applied crop plant biology and new tools for research and crop improvement. Unlimited access to a high-quality reference sequence is removing one of the major constraints in basic and applied research. This book summarizes the advanced knowledge of the composition of the barley genome, its genes and the much larger non-coding part of the genome, and how this information facilitates studying the specific characteristics of barley. One of the oldest domesticated crops, barley is the small grain cereal species that is best adapted to the highest altitudes and latitudes, and it exhibits the greatest tolerance to most abiotic stresses. With comprehensive access to the genome sequence, barley's importance as a genetic model in comparative studies on crop species like wheat, rye, oats and even rice is likely to increase.
