This book presents abiotic stresses that cause crop damage in the
range of 6-20%. Understanding the interaction of crop plants to the
abiotic stresses caused by heat, cold, drought, flooding,
submergence, salinity, acidity, etc., is important to develop
resistant crop varieties. Knowledge on the advanced genetic and
genomic crop improvement strategies including molecular breeding,
transgenics, genomic-assisted breeding, and the recently emerging
genome editing for developing resistant varieties in cereal crops
is imperative for addressing FPNEE (food, health, nutrition,
energy, and environment) security. Whole genome sequencing of these
crops followed by genotyping-by-sequencing has facilitated precise
information about the genes conferring resistance useful for gene
discovery, allele mining, and shuttle breeding which in turn opened
up the scope for 'designing' crop genomes with resistance to
abiotic stresses. The nine chapters each dedicated to a cereal crop
in this volume are deliberate on different types of abiotic
stresses and their effects on and interaction with crop plants;
enumerate on the available genetic diversity with regard to abiotic
stress resistance among available cultivars; illuminate on the
potential gene pools for utilization in interspecific gene
transfer; are brief on the classical genetics of stress resistance
and traditional breeding for transferring them to their cultivated
counterparts; elucidate on the success stories of genetic
engineering for developing abiotic stress-resistant crop varieties;
discuss on molecular mapping of genes and QTLs underlying stress
resistance and their marker-assisted introgression into elite
varieties; enunciate on different emerging genomics-aided
techniques including genomic selection, allele mining, gene
discovery, and gene pyramiding for developing adaptive crop
varieties with higher quantity and quality, and also elaborate some
case studies on genome editing focusing on specific genes for
generating abiotic stress-resistant crops.
With advances in agro-technology, cucurbits are now being grown
throughout the year. However, they are prone to biotic and abiotic
stresses resulting in significant yield loss. Sustainable
management of such stresses is a complex issue in the intensive
cultivation of cucurbits involving high levels of fertilization and
irrigation. Further, under the changing climatic conditions, pest
scenarios vary constantly, with invasive alien species of pests
becoming more common as a result of free trade and frequent
international travel. As such, agrochemicals are being used as
powerful weapons to combat the increasing number of pests and
diseases. Lack of proper crop management technologies, inaccurate
diagnosis, and indiscriminate and excessive use of pesticides are
major causes of pesticide resistance and resurgence, environmental
pollution, and hazards to the non-target biota. This comprehensive
book provides essential insights into the management of biotic and
abiotic stresses in cucurbit cultivation and re-evaluating the role
of agrochemicals, and gathers information on insect pests, mites,
nematodes, diseases and weeds, as well as on their sustainable
management from scattered sources. Written in language that is easy
to understand and including high-quality photographs, it is a
valuable resource for students, researchers, plant protection
specialists, extension workers, and growers.
This book provides a comprehensive overview of the current state of
knowledge on plant-microbiome interactions and associations. It
covers all major mechanistic approaches used to investigate
microbes' impacts on plant growth promotion, disease control and
health. The industrial manufacture of nitrogen currently accounts
for roughly 2% of the world's total energy consumption. Microbial
products are expected to reduce the need for costly fertilizers, as
well as chemical pesticides and fungicides. While beneficial
microorganisms are increasingly being used in agriculture, abiotic
and biotic stresses such as heat, drought, cold, and salt can
quickly kill or render them useless in the field. However,
discovering new and better treatments is a lengthy process due to
the considerable microbial diversity found in soils. Researchers
have now proposed using biotechnological approaches to accelerate
the process of microbial technology development. The fact that
plant-associated microbes stimulate plant growth and development is
well known, as the examples of rhizobia and mycorrhizal fungi show.
The mechanisms by which these microorganisms maintain plant growth
include the production of phytohormones, fixation of nitrogen, and
the mobilization of phosphorus and minerals. The plant microbiome
is also involved in pathogen suppression, and especially the root
microbiome acts as a protective shield against soil-borne
pathogens. A special feature of this book is its multidisciplinary
approach, spanning from plant microbiology/biocontrol, fungal and
bacterial endophytes, plant physiology, to biochemistry, proteomics
and genomics. It is ideally suited for researchers and student of
agri-biotechnology, soil biology and fungal biology.
The agricultural sector of medicinal (including plant stimulants)
and aromatic plants is characterized by an enormous number and
diversity of species. Only a few of them can be considered
cultivated crops in which significant breeding efforts are made.
For most species, however, breeding is performed in short-term
projects only. Therefore, basic knowledge about these species is
still fragmentary. Our intention is to compile and organize the
available information on the most commonly utilized plant species
into one publication, thereby providing a standardized resource for
the researchers and the grower community. This book therefore
provides reference source materials for a wide variety of plant
species used for human consumption due to their flavor, medicinal
or recreational properties. It is divided into a section of general
topics on genetic resources, breeding adaptation of analytic
methods and a compilation of basic data for DNA content, chromosome
number and mating system followed by a section of 20 monographs on
a species or species groups.
This book provides the first comprehensive overview of saline and
alkaline soils in Latin America, known for having one of the most
extensive surface of salt-affected soils in the world. It is
organized along two main axes: soils and vegetation. The book
discusses the occurrence of such soils in the region, focusing
mainly in management strategies for their sustainable use, and it
presents accounts of natural vegetation and crops in the various
environments of the region. Social impacts of such conditions and
ongoing projects to overcome them are considered. Likewise, the
book highlights physiological mechanisms that are responsible for
the negative effects these soils exert on crops and forest
resources and determine vegetation distribution in them. Plant
breeding challenges and new perspectives for such environments are
discussed. Technologies such as irrigation and drainage are
included. The readership includes soil and plant scientists, as
well as policy makers.
This book focuses on the effects of genotoxic agents causing
oxidative stress in plants. The book explores different kind of
chemicals which induces genotoxicity, their mechanism of action and
effects on plant health. Impacts at the physiological and molecular
levels are discussed. The book is of interest to teachers,
researchers and plant scientists. Also the book serves as
additional reading material for undergraduate and graduate students
of agriculture, forestry, ecology, soil science, and environmental
sciences. National and international agricultural scientists will
also find this to be a useful read.

Microbiomes and Plant Health: Panoply and Their Applications
includes the most recent advances in phytobiome research. The book
emphasizes the use of modern molecular tools such as smart delivery
systems for microbiol inoculation, next-generation sequencing, and
genome mapping. Chapters discuss a variety of applications and
examples, including the sugarcane microbiome, rhizoengineering,
nutrient recycling, sustainable agricultural practices and
bio-potential of herbal medicinal plants. Written by a range of
experts with real-world practical insights, this title is sure to
be an essential read for plant and soil microbiologists,
phytopathologists, agronomists, and researchers interested in
sustainable forestry and agriculture practices.
This book provides in-situ phytoremediation strategies that are
particularly well suited for developing nations. Its goal is to
promote the use of field-tested phytoremediation methods for
removing soil and water pollutants from agricultural, industrial,
military, and municipal sources. These strategies include using
algae and a variety of aquatic and terrestrial plants. The book
subsequently discusses the use of crops and native plants for
phytoremediation, and how phytoremediation efforts impact the
rhizosphere. After having finished the book, readers will be able
to directly adapt the strategies described here for their specific
purposes.
Medicinal plants are globally valuable sources of herbal products.
Plant-based remedies have been used for centuries and have had no
alternative in the western medicine repertoire, while others and
their bioactive derivatives are in high demand and have been the
central focus of biomedical research. As Medicinal plants move from
fringe to mainstream with a greater number of individuals seeking
treatments free of side effects, considerable attention has been
paid to utilize plant-based products for the prevention and cure of
human diseases. An unintended consequence of this increased demand,
however, is that the existence of many medicinal plants is now
threatened, due to their small population size, narrow distribution
area, habitat specificity, and destructive mode of harvesting. In
addition, climate change, habitat loss and genetic drift have
further endangered these unique species. Although extensive
research has been carried out on medicinal and aromatic plants,
there is relatively little information available on their global
distribution patterns, conservation and the associated laws
prevailing. This book reviews the current status of threatened
medicinal plants in light of increased surge in the demand for
herbal medicine. It brings together chapters on both wild
(non-cultivated) and domestic (cultivated) species having
therapeutic values. Thematically, conventional and contemporary
approaches to conservation of such threatened medicinal plants with
commercial feasibility are presented. The topics of interest
include, but not limited to, biotechnology, sustainable
development, in situ and ex situ conservation, and even the
relevance of IPR on threatened medicinal plants. We believe this
book is useful to horticulturists, botanists, policy makers,
conservationists, NGOs and researchers in the academia and the
industry sectors.
A transgenic organism is a plant, animal, bacterium, or other
living organism that has had a foreign gene added to it by means of
genetic engineering. Transgenic plants can arise by natural
movement of genes between species, by cross-pollination based
hybridization between different plant species (which is a common
event in flowering plant evolution), or by laboratory manipulations
by artificial insertion of genes from another species. Methods used
in traditional breeding that generate transgenic plants by
non-recombinant methods are widely familiar to professional plant
scientists, and serve important roles in securing a sustainable
future for agriculture by protecting crops from pest and helping
land and water to be used more efficiently.
There is worldwide interest in the biosafety issues related to
transgenic crops because of issues such as increased pesticide use,
increased crop and weed resistance to pesticides, gene flow to
related plant species, negative effects on nontarget organisms, and
reduced crop and ecosystem diversity. This book is intended to
provide the basic information for a wide range of people involved
in the release of transgenic crops. These will include scientists
and researchers in the initial stage of developing transgenic
products, industrialists, and decision makers. It will be of
particular interest to plant scientists taking up biotechnological
approaches to agricultural improvement for developing nations.

This book provides a conceptually organized framework to understand
the phenomenon of biological invasions at the Anthropocene global
scale. Most advances toward that aim have been provided from North
American and European researchers, with fewer contributions from
Australia and South Africa. Here we fill the void from the
Neotropics, focusing on the research experience in South American
countries, with a strong emphasis on Argentina and Chile. The text
is divided into two parts: The first half comprises self-contained
chapters, providing a conceptual, bibliographic and empirical
foundation in the field of invasion biology, from an Anthropocene
perspective. The second half reviews the ecology, biogeography, and
local impacts in South America of exotic species groups (European
rabbit, Eurasian wild boar, Canadian beaver, North American mink,
and Holarctic freshwater fishes), which are shown to be useful
models for case studies of global relevance.
Most projects in Landscape Ecology, at some point, define a
species-habitat association. These models are inherently spatial,
dealing with landscapes and their configurations. Whether coding
behavioral rules for dispersal of simulated organisms through
simulated landscapes, or designing the sampling extent of field
surveys and experiments in real landscapes, landscape ecologists
must make assumptions about how organisms experience and utilize
the landscape. These convenient working postulates allow modelers
to project the model in time and space, yet rarely are they
explicitly considered. The early years of landscape ecology
necessarily focused on the evolution of effective data sources,
metrics, and statistical approaches that could truly capture the
spatial and temporal patterns and processes of interest. Now that
these tools are well established, we reflect on the ecological
theories that underpin the assumptions commonly made during species
distribution modeling and mapping. This is crucial for applying
models to questions of global sustainability.
Due to the inherent use of GIS for much of this kind of
research, and as several authors research involves the production
of multicolored map figures, there would be an 8-page color insert.
Additional color figures could be made available through a digital
archive, or by cost contributions of the chapter authors. Where
applicable, would be relevant chapters GIS data and model code
available through a digital archive. The practice of data and code
sharing is becoming standard in GIS studies, is an inherent method
of this book, and will serve to add additional research value to
the book for both academic and practitioner audiences."
Transcription Factors for Abiotic Stress Tolerance in Plants
highlights advances in the understanding of the regulatory network
that impacts plant health and production, providing important
insights for improving plant resistance. Plant production worldwide
is suffering serious losses due to widespread abiotic stresses
increasing as a result of global climate change. Frequently more
than one abiotic stress can occur at once, for example extreme
temperature and osmotic stress, which increases the complexity of
these environmental stresses. Modern genetic engineering
technologies are one of the promising tools for development of
plants with efficient yields and resilience to abiotic stresses.
Hence deciphering the molecular mechanisms and identifying the
abiotic stress associated genes that control plant response to
abiotic stresses is a vital requirement in developing plants with
increased abiotic stress resilience. Addressing the various
complexities of transcriptional regulation, this book includes
chapters on cross talk and central regulation, regulatory networks,
the role of DOF, WRKY and NAC transcription factors, zinc finger
proteins, CRISPR/CAS9-based genome editing, C-Repeat (CRT) binding
factors (CBFs)/Dehydration responsive element binding factors
(DREBs) and factors impacting salt, cold and phosphorous stress
levels, as well as transcriptional modulation of genes involved in
nanomaterial-plant interactions. Transcription Factors for Abiotic
Stress Tolerance in Plants provides a useful reference by
unravelling the transcriptional regulatory networks in plants.
Researchers and advanced students will find this book a valuable
reference for understanding this vital area.
This textbook provides the first overview of plant-animal
interactions for twenty years focused on the needs of students and
professors. It discusses a range of topics from the basic
structures of plant-animal interactions to their evolutionary
implications in producing and maintaining biodiversity. It also
highlights innovative aspects of plant-animal interactions that can
represent highly productive research avenues, making it a valuable
resource for anyone interested in a future career in ecology.
Written by leading experts, and employing a variety of didactic
tools, the book is useful for students and teachers involved in
advanced undergraduate and graduate courses addressing areas such
as herbivory, trophic relationships, plant defense, pollination and
biodiversity.
