Cotton, the most important natural fiber crop, has been improved by conventional breeding-largely through planned hybridization of different cotton genotypes, since the discovery of Mendelian genetics. All these efforts resulted in the development of resilient high yielding cotton varieties. However, the progress through conventional breeding procedures is slow because of long lag periods for developing a variety, little control over the new genetic combinations, unwanted traits and lack of foolproof performance testing system. Genomic assays discovered over the last two decades have made it possible to understand the "language" of the genome by associating the genes with specific traits. Together with the more recently established gene-editing tools like CRISPR-Cas9, the cotton genome can be tailored much more precisely than ever before. In this regard, genetic information has been harnessed, through (i) sequencing of the progenitor and cultivated cotton species, (ii) ongoing mega pan-genome sequencing projects, (iii) genetic and physical mapping, and (iv) introgression of genes from alien sources, that resulted in the development of resilient cotton cultivars. These technologies have been deployed or are attempting to overcome the challenges of water shortage, excessive heat in most cotton growing regions, infectious diseases and infestation of insect pests, as well as rising production cost, for sustainable cotton production beyond 2030. In this book, new knowledge generated by the cotton research community and its application for developing resilient cotton are comprehensively summarized. This book contributed by well-known cotton researchers is a timely collection of the challenges and successes of precision cotton breeding in a changing environment.

Spirulena Platensis, a blue-green algae, has been recognized and used worldwide as a traditional source of protein in the food industry. The uses and mass cultivation of this algae have risen substantially due to an increased understanding of its biological systems. This text contains detailed descriptions of both the biology and the biotechnological uses of Spirulena Platensis. Part One focuses on the physiology, morphology, photosyntheses and genetics of laboratory cultures. Part Two discusses the practical uses in biotechnology industries, such as: the cultivation on flat-plate reactors; mass cultures outdoors; uses in wastewater treatment and the use of biomass. It offers critiques of the problems encountered and discussions of the future commercial prospects for large-scale production.

The coconut palm occupies a significant place in the world economy as an important subsistence crop in all the areas in which it is grown. Relatively few countries are able to export any quantity of coconut products because of increasing home demands coupled with low productivity. Yields are generally well below potential despite recent developments with improved planting stock and agronomic practices. In the last 50 years, both these aspects have received considerable attention, but the focus is shifting to investigate how the use of recently developed biotechnological techniques- can benefit the coconut industry. This volume, the result of the International Symposium on Coconut Biotechnology (held in December 1997 in Merida, Yucatan, Mexico), describes recent research in three important areas. Standard plant breeding techniques used with coconut have produced improved planting material, but progress is inevitably very slow. Can more rapid genetic improvement be obtained using molecular techniques? The papers presented in this section suggest that such techniques will open up exciting new prospects, but only after basic information has been gathered on the genetic status of existing coconut stocks. Research using microsatellite techniques seems to provide a useful tool to help to classifying these stocks. However, only a combination of classical breeding methods with modem techniques will lead to the rapid improvement which is required to supply material for urgent replanting programs.

Mitochondria are the product of a long evolutionary history. It is now a well established fact that mitochondria did evolve from free living bacteria being the common ancestor of both, eukaryotic mitochondria and -proteobacteria. Advances in genome sequencing, the establishment of in organello and in vitro assays to name only a few, contributed significantly to advances in plant mitochondrial research. Second generation sequencing and the ability to directly sequence and analyse the whole plant transcriptome certainly will help to develop the research on plant mitochondria to another level in the future. In this book the current knowledge about plant mitochondria is presented in a series of detailed chapters, which have been organized in five main sections: (i) dynamics, genes and genomes; (ii) transcription and RNA processing; (iii) translation and import; (iv) biochemistry, regulation and function; and (v) mitochondrial dysfunction and repair. These sections consist of two to five chapters, each written by well-known specialists in the field. This book thus provides a comprehensive inside in the field of plant mitochondria for the specialist. The addition of a glossary and text boxes to each chapter provides easy access for readers from other subjects and hopefully will attract young scientist to the fascinating and exiting field of plant mitochondria."

Over the last decade considerable progress has been made in white biotechnology research and further major scientific and technological breakthroughs are expected in the future. The first large-scale industrial applications of modern biotechnology have been in the areas of food and animal feed production (agricultural/green biotechnology) and in pharmaceuticals (medical/red biotechnology). In contrast, the productions of bioactive compounds through fermentation or enzymatic conversion are known as industrial or white biotchnology. The fungi are ubiquitous in nature and have been sorted out from different habitats, including extreme environments (high temperature, low temperature, salinity and pH); and associated with plants (Epiphytic, Endophytic and Rhizospheric). The fungal strains are beneficial as well as harmful for human beings. The beneficial fungal strains may play important roles in the agricultural, industrial, and medical sectors. The fungal strains and its product (enzymes, bioactive compounds, and secondary metabolites) are very useful for industry (e.g., the discovery of penicillin from Penicillium chrysogenum). This discovery was a milestone in the development of white biotechnology as the industrial production of penicillin and antibiotics using fungi moved industrial biotechnology into the modern era, transforming it into a global industrial technology. Since then, white biotechnology has steadily developed and now plays a key role in several industrial sectors providing both high value nutraceutical and pharmaceutical products. The fungal strains and bioactive compounds also play an important role in environmental cleaning. This volume covers the latest research developments related to value-added products in white biotechnology through fungi.

This book is an outgrowth of a UNESCO regional workshop entitled Culture Collection and Breeding of Edible Mushrooms. The purpose of the workshop is to provide participants with information on the principles and techniques involved in the genetics and breeding of edible mushrooms.

Fungi are an essential, fascinating and biotechnologically useful group of organisms with an incredible biotechnological potential for industrial exploitation. Knowledge of the world's fungal diversity and its use is still incomplete and fragmented. There are many opportunities to accelerate the process of filling knowledge gaps in these areas. The worldwide interest of the current era is to increase the tendency to use natural substances instead of synthetic ones. The increasing urge in society for natural ingredients has compelled biotechnologists to explore novel bioresources which can be exploited in industrial sector. Fungi, due to their unique attributes and broad range of their biological activities hold great promises for their application in biotechnology and industry. Fungi are an efficient source of antioxidants, enzymes, pigments, and many other secondary metabolites. The large scale production of fungal pigments and their utility provides natural coloration without creating harmful effects on entering the environment, a safer alternative use to synthetic colorants. The fungal enzymes can be exploited in wide range of industries such as food, detergent, paper, and also for removal toxic waste. This book will serve as valuable source of information as well as will provide new directions to researchers to conduct novel research in field of mycology. Volume 2 of "Industrially Important Fungi for Sustainable Development" provides an overview to understanding bioprospecting of fungal biomolecules and their industrial application for future sustainability. It encompasses current advanced knowledge of fungal communities and their potential biotechnological applications in industry and allied sectors. The book will be useful to scientists, researchers, and students of microbiology, biotechnology, agriculture, molecular biology, and environmental biology.

Apomixis in Plants is an important reference volume for researchers and students in all areas of botany, ecology, and plant breeding.

Abiotic stress drastically limits agricultural crop productivity worldwide. Climate change threatens the sustainable agriculture with its rapid and unpredictable effects, making it difficult for agriculturists and farmers to respond to the challenges cropping up from environmental stresses.In light of population growth and climate changes, investment in agriculture is the only way to avert wide scale food shortages. This challenge comes at a time when plant sciences are witnessing remarkable progress in understanding the fundamental processes of plant growth and development. Plant researchershave identifiedgenes controlling different aspects of plant growth and development, but many challenges still exist in creating an apt infrastructure, access to bioinformatics and good crop results. "Improvement of Crops in the Era of Climatic Changes, Volume2"focuses on many existing opportunities that can be applied methodically through conventional breeding, without touching upon the latest discoveries such as the power of genomics to applied breeding in plant biology.

Written by a diversefaction of internationally famedscholars, this volume adds new horizons in the field of crop improvement, genetic engineering and abiotic stress tolerance. Comprehensive and lavishly illustrated, "Improvement of Crops in the Era of Climatic Changes, Volume2"is a state-of-the-art guide to recent developmentsvis-a-visvarious aspects of plant responses in molecular and biochemical ways to create strong yields and overall crop improvement."

The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.

This book focuses on the evolution of plant viruses, their molecular classification, epidemics and management, covering topics relating to evolutionary mechanisms, viral ecology and emergence, appropriate analysis methods, and the role of evolution in taxonomy. The currently emerging virus species are increasingly becoming a threat to our way of life, both economically and physically. Plant viruses are particularly significant as they affect our food supply and are capable of rapidly spreading to new plant species. In basic research, plant viruses have become useful models to analyze the molecular biology of plant gene regulation and cell-cell communication. The small size of DNA genome of viruses possesses minimal coding capacity and replicates in the host cell nucleus with the help of host plant cellular machinery. Thus, studying virus cellular processes provides a good basis for explaining DNA replication, transcription, mRNA processing, protein expression and gene silencing in plants. A better understanding of these cellular processes will help us design antiviral strategies for plants. The book provides in-depth information on plant virus gene interactions with hosts, localization and expression and the latest advances in our understanding of plant virus evolution, their responses and crop improvement. Combining characterization of plant viruses and disease management and presenting them together makes it easy to compare all aspects of resistance, tolerance and management strategies. As such, it is a useful resource for molecular biologists and plant virologists alike.

Plant phenotyping is the thorough assessment of plant traits such as growth, development, adaptation, yield, quality, tolerance, resistance, architecture, and the basic measurement of individual quantitative parameters that form the basis for understanding of traits. Genetic approaches to understand plant growth and development have always benefitted from phenotyping techniques that are simple, rapid and measurable in units. The forward genetics approach is all about understanding the trait inheritance using the phenotypic data and in most cases it is the mutant phenotypes that formed the basis for understanding of gene functions.

With rapid advancement of genotyping techniques, high throughput genotyping has become a reality at costs people never imagined to be that low, but the phenotypic methods did not receive same attention. However, without quality phenotyping data the genotyping data cannot be effectively put to use in plant improvement. Therefore efforts are underway to develop high-throughput phenotyping methods in plants to keep pace with revolutionary advancement in genotyping techniques to enhance the efficiency of crop improvement programs. Keeping this in mind, we described in this book the best phenomic tools available for trait improvement in some of the world s most important crop plants.

This book offers comprehensive information on the genomics of spruces (Picea spp.), naturally abundant conifer tree species that are widely distributed in the Northern Hemisphere. Due to their tremendous ecological and economic importance, the management of forest genetic resources has chiefly focused on conservation and tree improvement. A draft genome sequence of the 20-gigabase Norway spruce genome was published in the journal Nature in 2013. Continuous efforts to improve the spruce genome assembly are underway, but are hindered by the inherent characteristics of conifer genomes: high amounts of repetitive sequences (introns and transposable elements) in the genome and large gene family expansions with regards to abiotic stress, secondary metabolism and spruces' defense responses to pathogens and herbivory. This book presents the latest information on the status of genome assemblies, provides detailed insights into transposable elements and methylation patterns, and highlights the extensive genomic resources available for inferring population genomics and climate adaptation, as well as emerging genomics tools for tree improvement programs. In addition, this volume features whole-genome comparisons among conifer species, and demonstrates how functional genomics can be used to improve gene function annotations. The book closes with an outlook on emerging fields of research in spruce genomics.

This book combines several ideas and philosophies and provides a detailed discussion on the value addition of fruits, vegetables, spices, plantation crops, floricultural crops and in forestry. Separate chapters address the packaging, preservation, drying, dehydration, total quality management and supply chain management of horticultural crops. The book explains value addition as a process of increasing the economic value and consumer appeal of a commodity with special reference to horticultural crops. Each chapter focuses on a specific area, exploring value addition as a production/ marketing strategy driven by customer needs and preferences. But, as such, it is also a more creative field, calling for more imagination than calculated, routine work. Value is added to the particular produce item when the product is still available when the season is out and the demand for the product exceeds the available supply. Value addition is an important factor in the growth and development of the horticultural sector, both in India and around the world. But very little information is available on this particular aspect of horticulture. Albert Einstein famously said, "Try not to become a man of success, but rather try to become a man of value." This message is not only true for those people who want to make more of themselves, but also for those who want their creation or product in any form to excel. And it certainly applies to horticultural crops, which are extremely perishable. It is true that loss reduction is normally less costly than equivalent increases in production. The loss of fresh produce can be minimized by adopting different processing and preservation techniques to convert the fresh vegetables into suitable value-added and diversified products, which will help to reduce the market glut during harvest season. Value-added processed products are products that can be obtained from main products and by-products after some sort of processing and subsequently marketed for an increased profit margin. Generally speaking, value-added products indicate that for the same volume of primary products, a higher price is achieved by means of processing, packing, enhancing the quality or other such methods. The integrated approach from harvesting to the delivery into the hands of the consumer, if handled properly, can add value to fresh produce on the market. But most of the fresh produce has a limited life, although it can be stored at appropriate temperature and relative humidity for the same time. If such produce is processed just after harvesting, it adds value and stabilizes the processed products for a longer time. Preparing processed products will provide more variety to consumers and improve the taste and other sensory properties of food. This will also promote their fortification with nutrients that are lacking in fresh produce. By adopting suitable methods for processing and value addition, the shelf life of fresh produce can be increased manifold, which supports their availability year-round to a wider spectrum of consumers on both the domestic and international market. With increased urbanization, rising middle class purchasing power, changing food habits and a decline in making preserved products in individual homes, there is now a higher demand for industry-made products on the domestic market. In spite of all these aspects, only 1-2.2% of the total produce is processed in developing countries, as compared to 40-83% in developed countries. The horticultural export industry offers an important source of employment for developing countries. For instance, horticulture accounts for 30% of India's agricultural GDP from 8.5% of cropped area. India is the primary producer of spices, second largest producer of fruits and vegetables and holds a prominent position with regard to most plantation crops in the world. The cultivation of horticultural crops is substantially more labor-intensive than growing cereal crops and offers more post-harvest opportunities for the development of value-added products. This book offers a valuable guide for students of horticulture, as well as a comprehensive resource for educators, scientists, industrial personnel, amateur growers and farmers.
