Plant improvement has shifted its focus from yield, quality and
disease resistance to factors that will enhance commercial export,
such as early maturity, shelf life and better processing quality.
Conventional plant breeding methods aiming at the improvement of a
self-pollinating crop, such as wheat, usually take 10-12 years to
develop and release of the new variety. During the past 10 years,
significant advances have been made and accelerated methods have
been developed for precision breeding and early release of crop
varieties. This edited volume summarizes concepts dealing with
germplasm enhancement and development of improved varieties based
on innovative methodologies that include doubled haploidy, marker
assisted selection, marker assisted background selection, genetic
mapping, genomic selection, high-throughput genotyping,
high-throughput phenotyping, mutation breeding, reverse breeding,
transgenic breeding, shuttle breeding, speed breeding, low cost
high-throughput field phenotyping, etc. It is an important
reference with special focus on accelerated development of improved
crop varieties.
This book explains about amino acids (AAs) which are not only
building blocks of protein, but are also signaling molecules as
well as regulators of gene expression and the protein
phosphorylation cascade. Additionally, AAs are key precursors for
syntheses of hormones and low-molecular-weight nitrogenous
substances with each having enormous biological importance. For
example, physiological concentrations of AA metabolites (e.g.,
nitric oxide, polyamines, glutathione, taurine, thyroid hormones,
and serotonin) are required for cell functions. Growing evidence
shows that humans and animals have dietary requirements for all
proteinogenic AAs. Mammals, birds, and fish also have species- and
age-dependent needs for some AA-related substances. However,
elevated levels of other products (e.g., ammonia, homocysteine,
H2S, and asymmetric dimethylarginine) are pathogenic factors for
neurological disorders, oxidative stress, and cardiovascular
disease. Thus, optimal amounts of AAs and their ratios in diets and
circulation are crucial for whole-body homeostasis and health.
Adequate provision of one or a mixture of functional AAs or
metabolites may be beneficial for ameliorating health problems at
various stages of the life cycle (e.g., fetal growth restriction,
neonatal morbidity and mortality, weaning-associated intestinal
dysfunction and wasting syndrome, obesity, diabetes, cardiovascular
disease, the metabolic syndrome, and infertility). Dietary
supplementation of these nutrients can also optimize the efficiency
of metabolic transformations to enhance muscle growth, milk
production, and athletic performance, while preventing excess fat
deposition and reducing adiposity. Therefore, functional AAs hold
great promise in improving the growth, health, and well-being of
individuals.
This book of protocols is devoted to the yellow coenzymes derived
from riboflavin or vitamin B2 and to the hundreds of enzymes whose
functionality depends on them, and represents a compendium of
techniques for working with flavoproteins or with the wide spectrum
of functions that flavoproteins can drive in the cells. Starting
with Rf production in microorganisms and the chemical, optical, and
redox properties of these fascinating molecules and moving along to
the variety and the peculiarity of some single flavoenzymes, the
volume explores the complexity of functions and distribution of
these molecules in the cell. Written for the highly successful
Methods in Molecular Biology series, chapters include introductions
to their respective topics, lists of the necessary materials and
reagents, step-by-step, readily reproducible laboratory protocols,
and tips on troubleshooting and avoiding known pitfalls.
Authoritative and practical, Flavin and Flavoproteins: Methods and
Protocols serves as an ideal guide for protein chemists interested
in purifying and characterizing flavoproteins, as well as
microbiologists, physiologists, and clinicians, who wish to further
study problems connected with flavoproteins.
Protein Interaction Networks, Volume 131 in the Advances in Protein
Chemistry and Structural Biology series, highlights new advances in
the field, with this new volume presenting interesting chapters
written by an international board of authors.
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.
Phyto-pathogens are one of the dominating components which badly
affect crop production. In light of the global food demand,
sustainable agricultural plans utilizing agrochemicals became
necessary. The role of beneficial microbes in the defense priming
of host plants has been well documented. This book details new
aspects of microbial-assisted plant protection and their role in
agricultural production, economy, and environmental sustainability.
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.
This book reviews the relationship between receptors, carbohydrate
moieties, and pathogenic surfaces and lectins' pathophysiology of
immune responses and examines the mechanisms of action of the
molecules for the treatment potentials. Increasing evidence has
suggested that lectin-carbohydrate interactions perform important
roles in various regulations of immune responses, but much remains
to be learned about these crucial properties and their interplay
with other molecules. In addition, a better understanding of the
structural and functional properties of lectin and the activated
immune response will be of critical importance for the development
of new diagnostic tools and therapeutic strategies. These key areas
are the focus of this book, which documents the latest research
findings in the field. Evidence is provided for the various lectin
types from animal and plant as well as microbial or marine lectins,
and this wide range of molecular knowledge directs us to various
diseases, including infectious diseases and cancer. In presenting
state-of-the-art knowledge on the interactions between lectin and
its interactions,the book will help to pave the way for the
development of novel targets for the prevention and treatment of
many disorders.
The Advanced Dairy Chemistry series was first published in four
volumes in the 1980s (under the title Developments in Dairy
Chemistry) and revised in three volumes in the 1990s and 2000s. The
series is the leading reference on dairy chemistry, providing
in-depth coverage of milk proteins, lipids, lactose, water and
minor constituents. Advanced Dairy Chemistry Volume 2: Lipids,
Fourth Edition, is unique in the literature on milk lipids, a broad
field that encompasses a diverse range of topics, including
synthesis of fatty acids and acylglycerols, compounds associated
with the milk fat fraction, analytical aspects, behavior of lipids
during processing and their effect on product characteristics,
product defects arising from lipolysis and oxidation of lipids, as
well as nutritional significance of milk lipids. In the years since
the publication of the third edition there have been significant
developments in milk lipids and these are reflected in changes to
this volume. Most topics included in the third edition are retained
in the current edition, which has been updated; in some cases, new
authors have given their perspective on certain topics. Chapters on
nutritional significance of dairy lipids have been considerably
revised.This authoritative work summarizes current knowledge on
milk lipids and suggests areas for further work. It will be very
valuable to dairy scientists, chemists and others working in dairy
research or in the dairy industry.
This book compiles recent research on the modification of nucleic
acids. It covers backbone modifications and conjugation of lipids,
peptides and proteins to oligonucleotides and their therapeutic
use. Synthesis and application in biomedicine and nanotechnology of
aptamers, fluorescent and xeno nucleic acids, DNA repair and
artificial DNA are discussed as well.
In this book, the major paradigm-shifting discoveries made in the
past century on key cellular nanomachines are described in great
detail: their complex yet precise and elegant design and function,
as well as the diseases linked to their dysfunction and the
therapeutic approaches to overcome them. The major focus of this
book is the "porosome" nanomachine, the universal secretory portal
in cells. This is an ideal book for students, researchers, and
professionals in the fields of nanoscience and nanotechnology.
The enzymology of milk and other products is of enormous
significance for the production and quality of almost every dairy
product. Milk itself is a complex biological fluid that contains a
wide range of enzymes with diverse activities, some of which have
identifiable functions while others are present as an accidental
consequence of the mechanism of milk secretion. Over time milk
enzymology has become an incredibly essential component of milk and
other dairy product production, and with advancing technology and
processing techniques, its importance is at its peak. Dairy
Enzymology presents an expansive overview of the enzymology of milk
and other dairy products, focusing on the use of indigenous and
endogenous enzymes in milk and exogenous enzymes in cheese
processing. A full section is dedicated to the enzymology of bovine
milk, focusing on the main families of indigenous enzymes as well
as their potential significance in the mammary gland plus the
technological significance for the properties of dairy products.
Implications for the manufacture and ripening of cheese plus the
use of enzymes such as alkaline phosphatase for measuring heat
treatment in milk are explored in full, and the role of milk
protease plasmin and other indigenous enzymes in the age-gelation
is focused on. Further sections focus on enzymes found in raw milk
and enzymes deliberately added for manufacture or modification of
properties and the manufacture of food ingredients from
dairy-derived ingredients. The key bacterial families are discussed
in depth as well as their known contributions to the quality of
dairy products. With its comprehensive scope and fully up-to-date
coverage of dairy product enzymology, this text is a singular
source for researchers looking to understand this essential dairy
processing aspect.
Infants and children are regularly fed with processed foods, yet
despite their importance in human development, these foods are
rarely studied. This important book provides an exhaustive analysis
of key technologies in the development of foods for babies and
children, as well as the regulation and marketing of these food
products. Contributors cover different aspects of food science and
technology in development of baby foods, making this text an unique
source of information on the subject. Food Science, Technology, and
Nutrition for Babies and Children includes relevant chapters on
infant milk formulas, essential fatty acids in baby foods, baby
food-based cereals and macro- and micronutrients. This book also
offers alternatives from the point of view of food technology for
babies and children with special diet regimes associated to
metabolic or enzymatic diseases such as allergy to casein,
phenylalanine (phenylketonuria or commonly known as PKU) and gluten
(celiac disease), or lactose intolerance. This book also addresses
some nutritional aspects of babies and children in terms of the
childhood obesity, child's appetite and parental feeding. With its
comprehensive scope and up-to-date coverage of issues and trends in
baby and children's foods, this is an outstanding book for food
scientists and technologists, food industry professionals,
researchers and nutritionists working with babies and children.
Mycotoxins are the metabolites of fungus and are reported to
contaminate nearly 25% of the food produced worldwide. The
mycotoxins of most significance are the aflatoxins due to their
severe health implications and their prevalence in food commodities
on a larger scale. Aflatoxins are produced by certain species of
fungi the most prominent among which are Aspergillus flavus, A.
parasiticus and A. nominous. Food commodities of African and South
Asian countries are especially reported to have aflatoxins well
beyond the allowable limits but due to the global trade of food
commodities developed countries are also prone towards the perils
of aflatoxins. Moreover, climate changes may have a substantial
impact on the distribution and global prevalence of aflatoxins in
the near future. The International Agency for Research on Cancer
(IARC) has classified the aflatoxins as group 1 category
carcinogen. Aflatoxins are also reported as teratogenic, mutagenic,
growth retardant, immunosuppressant and may also cause nervous
system and reproductive system disorders. Preventive approaches
involving good manufacturing from "farm to fork" are the major
focus of the current food industry. The aim of our book is to
provide readers with the most recent data and up-to-date studies
from aflatoxins research, with specific focuses on (i) the impact
of aflatoxins on human health, (ii) new approaches by the
researchers from different parts of the world to degrade aflatoxins
and (iii) potential preventive approaches that can significantly
lessen the burden of aflatoxins in food products

nano-morphologies, as well as the synthesis, characterization and
application of porous biopolymers.
An outstanding resource for anyone involved in the fi eld of
eco-friendly biomaterials for advanced technologies.
Mitochondria are sometimes called the powerhouses of eukaryotic
cells, because mitochondria are the site of ATP synthesis in the
cell. ATP is the universal energy currency, it provides the power
that runs all other life processes. Humans need oxygen to survive
because of ATP synthesis in mitochondria. The sugars from our diet
are converted to carbon dioxide in mitochondria in a process that
requires oxygen. Just like a fire needs oxygen to burn, our
mitochondria need oxygen to make ATP. From textbooks and popular
literature one can easily get the impression that all mitochondria
require oxygen. But that is not the case. There are many groups of
organismsm known that make ATP in mitochondria without the help of
oxygen. They have preserved biochemical relicts from the early
evolution of eukaryotic cells, which took place during times in
Earth history when there was hardly any oxygen avaiable, certainly
not enough to breathe. How the anaerobic forms of mitochondria
work, in which organisms they occur, and how the eukaryotic
anaerobes that possess them fit into the larger picture of rising
atmospheric oxygen during Earth history are the topic of this book.
Ribonucleic acid (RNA) is a macromolecule that plays a central role
in cell physiology: RNA molecules act as intermediates between the
deoxyribonucleic acid (DNA), where genetic information is stored,
and proteins, which perform the necessary functions within the
cell. Traditionally, the structural and functional properties of
RNA are closely linked to gene expression. However, RNA-based
enzymes, called ribozymes, are also involved in catalysis and small
RNAs regulate key cellular processes, such as cell growth,
division, differentiation, aging and death. RNA is a sensitive
macromolecule that can be easily damaged by environmental
conditions (ultraviolet radiation, oxidative stress) and biological
factors (ribonucleases, ribotoxins, CRISPR-Cas systems). Therefore,
cells have developed mechanisms to protect and/or repair RNA
molecules. This book presents an overview of the biology of RNA
damage, protection and repair in prokaryotes and eukaryotes.
Individual chapters cover the expression regulation, enzymology and
physiological role of such systems, and link them to important
human diseases such as cancer and degenerative diseases.
