This book examines the application of soybean genome sequences to
comparative, structural, and functional genomics. Since the
availability of the soybean genome sequence has revolutionized
molecular research on this important crop species, the book also
describes how the genome sequence has shaped research on transposon
biology and applications for gene identification, tilling and
positional gene cloning. Further, the book shows how the genome
sequence influences research in the areas of genetic mapping,
marker development, and genome-wide association mapping for
identifying important trait genes and soybean breeding. In closing,
the economic and botanical aspects of the soybean are also
addressed.
Privacy is a fundamental concern of all individuals in the modern
information-driven society, but information security goes beyond
digital and data-oriented approaches to include the basic
components of what makes us human. Protecting the Genetic Self from
Biometric Threats: Autonomy, Identity, and Genetic Privacy
considers all aspects of privacy and security relating to an
individual's DNA. With a concentration on fundamental human rights
as well as specific cases and examples, this essential reference
brings pertinent, real-world information to researchers,
scientists, and advocates for greater security and privacy in the
modern world.
Before Mendel, who came closest to the truth about heredity? This book examines the activities of sheep breeders able to transform the appearance and qualities of their stock by combining different traits of body or wool into new patterns. Exploiting what were then untried procedures - individual trait selection, very close inbreeding and progeny testing - they demonstrated inheritance from both sexes and showed how it could be stabilised. Major advances in breeding are associated with the English farmer Robert Bakewell (1725-1795). By the following century, when the same procedures had been established at breeding centres in central Europe, theory as well as practice became the subject of wider attention. In the Brno Sheep Breeders' Society, discussions of patterns of heredity finally gave way to the physiological question, 'What is inherited and how?' The question was posed by Cyrill Napp, abbot of the monastery to which Mendel was admitted six years later.
This book discusses the main stem cell niches under distinct
pathophysiological conditions. The role of tissue microenvironments
in stem cell regulation, as well as modern methodologies and new
techniques for the identification and characterization of stem cell
niches, are discussed by leading experts in the field. Chapters
describe the major components of various stem cell
microenvironments, such as cellular components, soluble factors,
cell-cell interactions, extra-cellular matrix proteins, and
physical forces. Stem Cell Microenvironments and Beyond is part of
the highly successful Advances in Experimental Medicine and Biology
series. It is essential reading for graduate students and
researchers in the field of stem cells or cell biology as well as
clinicians.
This volume brings together a set of reviews that provide a summary
of our current knowledge of the proteolytic machinery and of the
pathways of protein breakdown of prokaryotic and eukaryotic cells.
Intracellular protein degradation is much more than just a
mechanism for the removal of incorrectly folded or damaged
proteins. Since many short-lived proteins have important regulatory
functions, proteolysis makes a significant contribution to many
cellular processes including cell cycle regulation and
transciptional control. In addition, limited proteolytic cleavage
can provide a rapid and efficient mechanism of enzyme activation or
inactivation in eukaryotic cells.
In the first chapter, Maurizi provides an introduction to
intracellular protein degradation, describes the structure and
functions of bacterial ATP-dependent proteases, and explores the
relationship between chaperone functions and protein degradation.
Many of the principles also apply to eukaryotic cells, although the
proteases involved are often not the same. Interestingly,
homologues of one of the bacterial proteases, Ion protease, have
been found in mitochondria in yeast and mammals, and homologues of
proteasomes, which are found in all eukaryotic cells (see below),
have been discovered in some eubacteria.
Studies of proteolysis in yeast have contributed greatly to the
elucidation of both lysosomal (vacuolar) and nonlysosomal
proteolytic pathways in eukaryotic cells. Thumm and Wolf (chapter
2) describe studies that have elucidated the functions of
proteasomes in nonlysosomal proteolysis and the contributions of
lysosomal proteases to intracellular protein breakdown. Proteins
can be selected for degradation by a variety of differen
mechanisms. The ubiquitin system is one complex and highly
regulated mechanism by which eukaryotic proteins are targetted for
degradation by proteosomes. In chapter 3, Wilkinson reviews the
components and functions of the ubiquitin system and considers some
of the known substrates for this pathway which include cell cycle
and transcriptional regulators.
The structure and functions of proteosomes and their regulatory
components are described in the two subsequent chapters by Tanaka
and Tanahashi and by Dubiel and Rechsteiner. Proteasomes were the
first known example of threonine proteases. They are multisubunit
complexes that, in addition to being responsible for the turnover
of most short-lived nuclear and cytoplasmic protein, are also
involved in antigen processing for presentation by the MHC class I
pathway. Recent studies reviewed by McCracken and colleagues
(chapter 6) lead to the exciting conclusion that some ER-associated
proteins are degraded by cytosolic proteasomes.
Lysosomes are responsible for the degradation of long-lived
proteins and for the enhanced protein degradation observed under
starvation conditions. In chapter 7 Knecht and colleagues review
the lysosomal proteases and describe studies of the roles of
lysosomes and the mechanisms for protein uptake into lysosomes.
Methods of measuring the relative contribution of different
proteolytic systems (e.g., ubiquitin-proteasome pathway,
calcium-dependent proteases, lysosomes) to muscle protein
degradation, and the conclusions from such studies, are reviewed by
Attai and Taillinder in the following chapter.
Finally, proteases play an important role in signaling apoptosis by
catalyzing the limited cleavage of enzymes. Mason and Beyette
review the role of the major players, caspases, which are both
activated by and catalyze limite proteolysis, and also consider the
involvement of other protoelytic enzymes in this pathway leading
cell death.

vectors for cancer therapy.
White biotechnology, or industrial biotechnology as it is also
known, refers to the use of living cells and/or their enzymes to
create industrial products that are more easily degradable, require
less energy, create less waste during production and sometimes
perform better than products created using traditional chemical
processes. 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. Fungi are
ubiquitous in nature and have been sorted out from different
habitats, including extreme environments (high temperature, low
temperature, salinity and pH), and may be 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 their
products (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 developments and research in white biotechnology with a
focus on diversity and enzymes.
Birds catch the public imagination like no other group of animals;
in addition, birders are perhaps the largest non-professional
naturalist community. Genomics and associated bioinformatics have
revolutionised daily life in just a few decades. At the same time,
this development has facilitated the application of genomics
technology to ecological and evolutionary studies, including
biodiversity and conservation at all levels. This book reveals how
the exciting toolbox of genomics offers new opportunities in all
areas of avian biology. It presents contributions from prominent
experts at the intersection of avian biology and genomics, and
offers an ideal introduction to the world of genomics for students,
biologists and bird enthusiasts alike. The book begins with a
historical perspective on how genomic technology was adopted by
bird ecology and evolution research groups. This led, as the book
explains, to a revised understanding of avian evolution, with
exciting consequences for biodiversity research as a whole. Lastly,
these impacts are illustrated using seminal examples and the latest
discoveries from avian biology laboratories around the world.
This book highlights the role of the Translationally Controlled
Tumor Protein (TCTP) in cell signaling, cell fate and the resulting
connection to disease development. It begins by discussing the
structure/function of TCTP, before exploring its role in different
species ranging from plants to Drosophila and covering fields such
as development, the cytoskeleton, cell division, DNA fragility and
apoptosis. In turn, the book's final section is devoted to the role
of TCTP in disease, namely asthma and diverse cancers, and
ultimately as a target for the treatment of malignancies. What is
the common denominator between all these processes and why is TCTP
necessary in order for them to occur, even in the worst case such
as cancer? The book seeks to provide meaningful answers to this and
other key questions. Presenting a broad and revealing view on the
topic, it offers an informative guide for scientists and students
alike.

What will our lives be like fifty years from now? What will we know
about ourselves as humans, and how will that affect our lives? It's
impossible to know the future for certain, but one thing we do
know--perhaps nothing will alter our future more than the Genetics
Revolution of the past thirty-five years. This book clarifies the
history and examines the possible impact of five major areas of
genetic research:
- The Human Genome Project and genetic engineering
- In vitro fertilization (IVF) and the technology of
reproduction
- The Human Genome Diversity Project, which is studying the
variation of the human genome
- Embryonic stem-cell research
- Cloning
All of these areas of research produce two reactions among the
general public--hope for the improvement of people's lives, and
fear of science out of control. The Genetics Revolution examines
the scientific, social, and political impacts of the genetics on
everyday life--in the past, in the present, and in the future. Each
specific topic is contained within its own chapter for ease in
accessing specific information. This is an ideal resource for
students, teachers, and others preparing research papers. In
addition, it integrates science and social science topics in a way
that supports topics in the school curricula. The book contains
documented, current information that both supports and challenges
current thinking about genetics.
Advances in Agronomy, Volume 144, the newest release in a serial

Instruction Manual: A Review of Gypsum Use in Agriculture,
Preventive Weed Management in Direct-Seeded Rice: Targeting the
Weed Seedbank, Current Approaches and Future Trends in Compost
Quality Criteria for Agronomic, Environmental and Human Health
Benefits, and Grain Legume Production and Use in European
Agricultural Systems. This highly regarded series contains an
eclectic group of reviews by leading scientists throughout the
world. As always, the subjects covered are rich, varied and
comprehensively covered.
The Wonder of Life takes you from Earth's beginning and describes
the events that preceded man and carries you along the path of
man's education. This came through wars, then religion, and always
through the silent killers of man as disease became one of the
major carriers of education as well as death. You will journey
through the battles with the silent killers and understand how man
went from a defensive mode to one of the aggressor with the
invention of the microscope. Follow the progress of the wins over
the Staff infections, to the use of penicillin during the war and
then the defeat of Polio; always in the search of what made man
tick. This carries him through the discovery of DNA, the genetic
code, AIDS, the human genome and to today's great hope of the use
of stem cells to correct for the body's malfunction of its organs.
It's an exciting story told in a novel manner for the layman to
understand.
A TIMES ENVIRONMENT AND SCIENCE BOOK OF THE YEAR 2022 'The ideal
guide to what is not just a fiendishly complex area of science but
also an ethical minefield' Mail on Sunday A new gene editing
technology, invented just seven years ago, has turned humanity into
gods. Enabling us to manipulate the genes in virtually any organism
with exquisite precision, CRISPR has given scientists a degree of
control that was undreamt of even in science fiction. But CRISPR is
just the latest, giant leap in a long journey to master genetics.
The Genetic Age shows the astonishing, world-changing potential of
the new genetics and the possible threats it poses, sifting between
fantasy and the reality when it comes to both benefits and dangers.
By placing each phase of discovery, anticipation and fear in the
context of over fifty years of attempts to master the natural
world, Matthew Cobb, the Baillie-Gifford-shortlisted author of The
Idea of the Brain, weaves the stories of science, history and
culture to shed new light on our future. With the powers now at our
disposal, it is a future that is almost impossible to imagine - but
it is one we will create ourselves.
