Arsenic is likely the most talked-about metalloid in the modern
world because of its toxic effects on both animal and plants.
Further, arsenic pollution is now producing negative impacts on
food security, especially in many south Asian countries. Since
plants are a major food source, their adaptation to As-rich
environments is essential, as is being informed about recent
findings on multifarious aspects of the mechanisms of arsenic
toxicity and tolerance in plants. Although numerous research works
and review articles have been published in journals, annual reviews
and as book chapters, to date there has been no comprehensive book
on this topic. This book contains 19 informative chapters on
arsenic chemistry, plant uptake, toxicity and tolerance mechanisms,
as well as approaches to mitigation. Readers will be introduced to
the latest findings on plant responses to arsenic toxicity, various
tolerance mechanisms, and remediation techniques. As such, the book
offers a timely and valuable resource for a broad audience,
including plant scientists, soil scientists, environmental
scientists, agronomists, botanists and molecular biologists.
Senescence Signalling and Control in Plants discusses the studies
showing the importance of hormone action on developmental
senescence. It shows the involvement of various signaling
components (such as EIN2, LOX2) and transcription factors (such as
oresara1 or ORE1) in controlling hormonal activity during
senescence. Further, the involvement of various micro RNAs (miR164,
miR319) in regulating leaf senescence are discussed. Through this
book, the authors throw light on all the reverse and forward
genetic approaches to reveal the role of various other
phytohormones regulating plant senescence and the molecular
mechanisms involved. Chapters on relevant topics are contributed by
experts working in the area, making this a comprehensive treatise
designed to provide an in-depth analysis on the subject matter.
Plant endophytes are a potential source for the production of
bioactive compounds that can fight against devastating diseases in
both plants and humans. Among these endophytic microorganisms,
endophytic fungi are one of the dominant group of microorganisms
with a potential role in plant growth promotion and the discovery
of noble bioactive natural products. Endophytic fungi possess
several bioactivities like anticancer, antimicrobial, insecticidal,
plant growth stimulants, crop protection, phytoremediation, etc.
Presence of modular biosynthetic genes clusters like PKS and NRPS
in several endophytic fungi underscores the need to understand and
explore such organisms. This volume presents and demonstrates the
applied aspects of endophytic fungi. Practical applications of such
endophytes are discussed in detail, including studies in
pharmaceutical development and agricultural management of important
microbial diseases. The beneficial effects that endophytic fungi
provide to host plants-enhancing growth, increasing fitness,
strengthening tolerance to abiotic and biotic stresses through
secondary metabolites-are also discussed. The reader is provided
with a comprehensive and detailed understanding of such
relationships between endophytic fungi and their host.
Sugarcane enjoys a prominent position among agro-industrial crops
and is commercially grown in 115 tropical and subtropical countries
around the world. However, fluctuations in sugar prices have forced
the sugarcane industry worldwide to broaden its revenue base by
moving from single-commodity manufacturing to a range of
value-added products. Utilizing the by-products in an innovative
manner to create value-added products is the new course of action
for sugar-producing countries. For many years sugarcane was
regarded as a single-product crop, i.e., only useful for producing
sugar. Its actual potential is now increasingly being recognised by
the industry and there is a growing trend toward the manufacturing
of allied products from sugarcane. Therefore, the focus is now on
the establishment of sugar-agro-industry complexes, processing not
just sugar but a range of other products. This book provides a
comprehensive overview of sugarcane not only as a source of
sweetening agents but also for many other uses, including as a
source of bio-energy. It also explores the trend of sugar
consumption and suggests practices to curb the consumption of sugar
products in order to tackle obesity and reduce public health costs.
The book underscores the need to diversify sugarcane and highlights
means of doing so, while also addressing various innovations and
technologies being developed in connection with sugar, sugar
derivatives, and sugar industry by-products for sustainable
utilization in the sugar-agro industry. Accordingly, it offers a
valuable resource for professionals and R&D units in the sugar
industry, and for students of agronomy and related fields.
Fungi are eukaryotic microorganisms that include both unicellular
and multicellular species. They have a worldwide distribution and a
wide range of applications in diverse sectors, from environmental,
food and medicine to biotechnological innovations. Fungal
biochemical genetics involves the study of the relationships
between genome, proteome and metabolome, and the underlying
molecular processes in both native and bioengineered fungi. This
book provides a valuable resource on the challenges and potential
of fungal biotechnology and related bioengineering and functional
diversity for various industrial applications in the food,
environmental, bioenergy and biorefining, and the biopharma
sectors. In comparison to previous and related publications in the
area of applied myco-biotech-engineering, this book bridges a
knowledge gap in the areas related to prospects and investment as
well as intellectual and technical issues. This book also provides
information on recent commercial and economic interests in the area
by juxtaposing the developments achieved in recent worldwide
research and its many challenges.
Ornamental plants are economically important worldwide. Both
growers and consumers ask continuously for new, improved varieties.
Although there are numerous ornamental species, ornamental plant
breeding and plant breeding research is mainly limited to some
major species. This book focuses on the recent advances and
achievements in ornamental plant breeding. The first part of the
book focuses on plant traits and breeding techniques that are
typical for ornamental plants. Eminent research groups write these
general chapters. For plant traits like flower colour or shape,
breeding for disease resistance and vase or shelf life are
reviewed. General technical plant breeding chapters deal with
mutation breeding, polyploidisation, in vitro breeding techniques
and new developments in molecular techniques. The second part of
the book consists of crop-specific chapters. Here all economically
major ornamental species are handled together with selected
representative species from different plant groups (cut flowers,
pot plants, woody ornamental plants). In these crop-specific
chapters, the main focus is on recent scientific achievements over
the last decade.
This book highlights the latest findings on fundamental aspects of
composting, the interaction of various microorganisms, and the
underlying mechanisms. In addition to addressing modern tools and
techniques used for composting research, it provides an overview of
potential composting applications in both agriculture and
environmental reclamation. Composting is the process of organic
waste decomposition, mediated by microorganisms. The end-product is
called 'compost' and can be used as a supplement to improve soil
fertility. As the municipal waste generated in most developing
countries contains a substantial amount of organic matter suitable
for composting, this technology offers a win-win opportunity for
stakeholders in terms of disposing of organic waste and providing
organic fertilizers for agriculture. In addition, using compost
reduces the dependency on harmful chemical fertilizers, and
represents a sustainable and environmentally friendly alternative.
Plant Nanobionics, Volume 2 continues the important discussion of
nanotechnology in plants, but focuses with a focus on biosynthesis
and toxicity. This book discusses novel approaches to biosynthesis
of nanoparticles for the increase of plant production systems,
controlled release of agrochemicals and management of plant biotic
stress. Green biosynthesis of metallic nanoparticles from bee
propolis, artificial photosynthesis and hybrid structures are
presented. Although engineered nanoparticles have great potential
for solving many agricultural and societal problems, their
consequences on the ecosystems and environment must be responsibly
considered. This volume aims to contribute to the limited
literature on this topic through its comprehensive examination of
nanoparticle toxicity on plants, microbes and human health.
Environmental risks with recent data are discussed as well as risks
associated with the transfer of nanoparticles through the food
chain. This volume highlights the study of a mechanistic approach
and the study of nanoparticles towards nanobionics. The application
of polymeric materials for smart packing in the food industry and
agriculture sector as well as the future of nanomaterials in
detecting soil microbes for environmental remediation are also
included.

Population genomics has revolutionized various disciplines of
biology including population, evolutionary, ecological and
conservation genetics, plant and animal breeding, human health,
medicine and pharmacology by allowing to address novel and
long-standing questions with unprecedented power and accuracy. It
employs large-scale or genome-wide genetic information and
bioinformatics to address various fundamental and applied aspects
in biology and related disciplines, and provides a comprehensive
genome-wide perspective and new insights that were not possible
before. These advances have become possible due to the development
of new and low-cost sequencing and genotyping technologies and
novel statistical approaches and software, bioinformatics tools,
and models. Population genomics is tremendously advancing our
understanding the roles of evolutionary processes, such as
mutation, genetic drift, gene flow, and natural selection, in
shaping up genetic variation at individual loci and across the
genome and populations; improving the assessment of population
genetic parameters or processes such as adaptive evolution,
effective population size, gene flow, admixture, inbreeding and
outbreeding depression, demography, and biogeography; resolving
evolutionary histories and phylogenetic relationships of extant,
ancient and extinct species; understanding the genomic basis of
fitness, adaptation, speciation, complex ecological and
economically important traits, and disease and insect resistance;
facilitating forensics, genetic medicine and pharmacology;
delineating conservation genetic units; and understanding the
genetic effects of resource management practices, and assisting
conservation and sustainable management of genetic resources. This
Population Genomics book discusses the concepts, approaches,
applications and promises of population genomics in addressing most
of the above fundamental and applied crucial aspects in a variety
of organisms from microorganisms to humans. The book provides
insights into a range of emerging population genomics topics
including population epigenomics, landscape genomics, seascape
genomics, paleogenomics, ecological and evolutionary genomics,
biogeography, demography, speciation, admixture, colonization and
invasion, genomic selection, and plant and animal domestication.
This book fills a vacuum in the field and is expected to become a
primary reference in Population Genomics world-wide.
Currently, there is a need for new management practices for fruit
orchards in order to sustain the growth and productivity of various
fruit crops. In addition, due to the continuous growth in the
world's population, there is a demand for adequate food which is
produced from the same sources of water and soils. The main factors
limiting agricultural production are droughts and the population
growth; this makes it important to prevent fruit production from
being subject to climatic hazards. This book enhances the growth
and productivity of fruit trees through different techniques, such
as artificial intelligence optimization for soil conditioner,
site-specific nutrient management in orchards in fertilizing as an
application of smart agriculture, irrigation, modeling of
parameters of water requirements in fruit orchards, and up-to-date
trends in vineyard practices. The book also explores pest control
on orchards to increase the efficiency of pesticides and protect
the environment and discusses the shading of citrus orchards to
avoid negative impacts such as rising temperatures and heatwaves on
citrus productivity. Finally, the book discusses the carbon and
water footprint for various fruit orchards. This book is ideal for
researchers and academics of horticultural science, agricultural
organizations, fruit growers, and economics and data analyzers.
With more than 500 species distributed all around the Northern
Hemisphere, the genus Quercus L. is a dominant element of a wide
variety of habitats including temperate, tropical, subtropical and
mediterranean forests and woodlands. As the fossil record reflects,
oaks were usual from the Oligocene onwards, showing the high
ability of the genus to colonize new and different habitats. Such
diversity and ecological amplitude makes genus Quercus an excellent
framework for comparative ecophysiological studies, allowing the
analysis of many mechanisms that are found in different oaks at
different level (leaf or stem). The combination of several
morphological and physiological attributes defines the existence of
different functional types within the genus, which are
characteristic of specific phytoclimates. From a landscape
perspective, oak forests and woodlands are threatened by many
factors that can compromise their future: a limited regeneration,
massive decline processes, mostly triggered by adverse climatic
events or the competence with other broad-leaved trees and conifer
species. The knowledge of all these facts can allow for a better
management of the oak forests in the future.
Global climate change requires the development of programs that
consider the active restoration of degraded forests and the use of
native trees in afforestation to preserve the natural environment.
International commitments like the UN REDD program, the Montreal
Process and the Convention on Biological Diversity call for the
breeding of species rarely contemplated by large industrial
companies. Low-intensity breeding is the most rational strategy for
those species: simple but robust, and not dependent on continuously
increasing funding, and therefore effective even with a relatively
small budget. It commonly focuses on high genetic diversity rather
than improving economic traits and adaptability rather than
productivity. Controlled crosses with full pedigrees typical of
high-intensity breeding are replaced by open pollination. This book
presents state-of-the-art breeding strategies from the last two
decades for several forest tree species of prime importance in the
natural forests of Argentina. They are distributed in the three
main forestry ecoregions of the country: the subtropical dry forest
(Chaco), the subtropical rain forests (Yungas and Alto Parana
rainforests) and the temperate forests of Patagonia. The book also
discusses the genetic patterns of the selected species defined
using genetic markers together with the analysis of the variation
in quantitative traits. Further, it examines the crucial features
of their reproductive biology, such as the mating system and gene
flow and describes the current breeding programs. Lastly, it
presents the latest developments in genetic resources and their
emerging applications, concluding with some reflections and
perspectives related to the conditioning imposed by climate change.
