Rapid changes and significant progress have been made in the
Agrobacterium field, such as genetically transforming plants for
both basic research purposes and agricultural development. In
Agrobacterium Protocols, Third Edition, Volumes 1 and 2, a team of
leading experts and veteran researchers describe in detail
techniques for delivering DNA to plant cells and permanently
altering their genomes. This edition emphasizes agricultural crops
and plant species with economic values, with updated protocols on
32 plant species and protocols involving 19 new species. Together
with the 1st and 2nd editions, these two volumes offer
Agrobacterium-mediated genetic transformation protocols for a total
of 76 plant species. For a number of important plants such as rice,
barley, wheat and citrus, multiple protocols using different
starting plant materials for transformation are included. Volume 2
contains 29 chapters with updated techniques for industrial plants,
root plants, nuts and fruits, tropic plants, and other important
plant species. Written in the highly successful Methods in
Molecular Biology series format, 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 cutting-edge, Agrobacterium Protocols, Third
Edition facilitates the transfer of this rapidly developing
technology to all researchers in both fundamental and applied
biology.
This book offers a methodical explanation of our biomass-driven
ecosystem, the undeniable uncertainties posed by the response of
vegetation to changes in environmental conditions and the fact that
humans everywhere have an interest, even an obligation, to
cooperate in a global campaign to combat climate change.
Microbial Nanobionics: Volume 2, Basic Research Applications
continues the important discussion of microbial nanoparticle
synthesis with a focus on the mechanistic approach of biosynthesis
towards nanobionics. This volume also explores the toxicity of
nanomaterials in microbes and their effect on human health and the
environment. Special Emphasis is given to the use of polymeric
nanomaterials in smart packing for the food industry and
agricultural sector. The future of nanomaterials for detection of
soil microbes and their interactions and tools for environmental
remedies is also comprehensively covered. The rich biodiversity of
microbes make them excellent candidates for potential nanoparticle
synthesis biofactories. Through a better understanding of the
biochemical and molecular mechanisms of the microbial biosynthesis
of metal nanoparticles, the rate of synthesis can be better
developed and the monodispersity of the product can be enhanced.
The characteristics of nanoparticles can be controlled via
optimization of important parameters, such as temperature, pH,
concentration and pressure, which regulate microbe growth
conditions and cellular and enzymatic activities. Large scale
microbial synthesis of nanoparticles is a sustainable method due to
the non-hazardous, non-toxic and economical nature of these
processes. The applications of microbial synthesis of nanoparticles
are wide and varied, spanning the industrial, biomedical and
environmental fields. Biomedical applications include improved and
more targeted antimicrobials, biosensing, imaging and drug
delivery. In the environmental fields, nanoparticles are used for
bioremediation of diverse contaminants, water treatment, catalysis
and production of clean energy. With the expected growth of
microbial nanotechnology, this volume will serve as a comprehensive
and timely reference.
This volume examines the molecular basis of all aspects of cell
division and cytokinesis in plants. It features 19 chapters
contributed by world experts in the specific research fields,
providing the most comprehensive and up-to-date knowledge on cell
division control in plants. The editors are veterans in the field
of plant molecular biology and highly respected worldwide.
Hugh P. Possingham Landscape-scale conservation planning is coming
of age. In the last couple of decades, conservation practitioners,
working at all levels of governance and all spatial scales, have
embraced the CARE principles of conservation planning -
Comprehensiveness, Adequacy, Representativeness, and Efficiency.
Hundreds of papers have been written on this theme, and several
different kinds of software program have been developed and used
around the world, making conservation planning based on these
principles global in its reach and influence. Does this mean that
all the science of conservation planning is over - that the
discovery phase has been replaced by an engineering phase as we
move from defining the rules to implementing them in the landscape?
This book and the continuing growth in the literature suggest that
the answer to this question is most definitely 'no. ' All of
applied conservation can be wrapped up into a single sentence: what
should be done (the action), in what place, at what time, using
what mechanism, and for what outcome (the objective). It all seems
pretty simple - what, where, when, how and why. However stating a
problem does not mean it is easy to solve.
Genetic erosion is the loss of genetic diversity within a species.
It can happen very quickly, due to catastrophic events, or changes
in land use leading to habitat loss. But it can also occur more
gradually and remain unnoticed for a long time. One of the main
causes of genetic erosion is the replacement of local varieties by
modern varieties. Other causes include environmental degradation,
urbanization, and land clearing through deforestation and brush
fires. In order to conserve biodiversity in plants, it is important
to targets three independent levels that include ecosystems,
species and genes. Genetic diversity is important to a species'
fitness, long-term viability, and ability to adapt to changing
environmental conditions. Chapters in this book are written by
leading geneticists, molecular biologists and other specialists on
relevant topics on genetic erosion and conservation genetic
diversity in plants. This divisible set of two volumes deals with a
broad spectrum of topics on genetic erosion, and approaches to
biodiversity conservation in crop plants and trees. Volume 1 deals
with indicators and prevention of genetic erosion, while volume 2
covers genetic diversity and erosion in a number of plants species.
These two volumes will also be useful to botanists,
biotechnologists, environmentalists, policy makers,
conservationists, and NGOs working to manage genetic erosion and
biodiversity.
This book provides a comprehensive overview of the benefits of
biofertilizers as an alternative to chemical fertilizers and
pesticides. Agricultural production has increased massively over
the last century due to increased use of chemical fertilizers and
pesticides, but these gains have come at a price. The chemicals are
not only expensive; they also reduce microbial activity in
agricultural soils and accumulate in the food chain, with
potentially harmful effects for humans. Accordingly, it is high
time to explore alternatives and to find solutions to overcome our
increasing dependence on these chemicals. Biofertilizers, which
consist of plant remains, organic matter and microorganisms, might
offer an alternative. They are natural, organic, biodegradable,
eco-friendly and cost-effective. Further, the microbes present in
the biofertilizers are important, because they produce nutrients
required for plant growth (e.g., nitrogen, phosphorus, potassium),
as well as substances essential for plant growth and development
(e.g., auxins and cytokinins). Biofertilizers also improve the
physical properties, fertility and productivity of soil, reducing
the need for chemical fertilizers while maintaining high crop
yield. This makes biofertilizers a powerful tool for sustainable
agriculture and a sustainable environment. The book covers the
latest research on biofertilizers, ranging from beneficial fungal,
bacterial and algal inoculants; to microbes for bioremediation,
wastewater treatment; and recycling of biodegradable municipal,
agricultural and industrial waste; as well as biocontrol agents and
bio-pesticides. As such, it offers a valuable resource for
researchers, academics and students in the broad fields of
microbiology and agriculture.
With an ever-increasing human population, the demand placed upon
the agriculture sector to supply more food is one of the greatest
challenges for the agrarian community. In order to meet this
challenge, environmentally unfriendly agroch- icals have played a
key role in the green revolution and are even today commonly
recommended to circumvent nutrient de?ciencies of the soils. The
use of ag- chemicals is, though, a major factor for improvement of
plant production; it causes a profound deteriorating effect on soil
health (soil fertility) and in turn negatively affects the
productivity and sustainability of crops. Concern over disturbance
to the microbial diversity and consequently soil fertility (as
these microbes are involved in biogeochemical processes), as well
as economic constraints, have prompted fun- mental and applied
research to look for new agro-biotechnologies that can ensure
competitive yields by providing suf?ciently not only essential
nutrients to the plants but also help to protect the health of
soils by mitigating the toxic effects of certain pollutants. In
this regard, the role of naturally abundant yet functionally fully
unexplored microorganisms such as biofertilizers assume a special
signi?cance in the context of supplementing plant nutrients, cost
and environmental impact under both conventional practices and
derelict environments. Therefore, current devel- ments in
sustainability involve a rational exploitation of soil microbial
communities and the use of inexpensive, though less bio-available,
sources of plant nutrients, which may be made available to plants
by microbially-mediated processes.
The first synthesis of current research regarding Everglades
microbial community structure and function, this book provides an
understanding of the physical and chemical factors affecting the
structure of microbial communities, including nutrient effects, sea
level rise, and other potential stressors. The book integrates
traditional research on algal and bacterial structure and function,
helping to provide a more holistic understanding of the varying
microbial communities throughout the Everglades. From periphyton,
to soils and detritus, to flocculent organic matter, Microbiology
of the Everglades Ecosystem covers new and emerging methods and
their global application.
The interactions between the plant, soil and microbes are complex
in nature. Events may be antagonistic, mutualistic or synergistic,
depending upon the types of microorganisms and their association
with the plant and soil in question. Multi-trophic tactics can
therefore be employed to nourish plants in various habitats and
growth conditions. Understanding the mechanisms of these
interactions is thus highly desired in order to utilize the
knowledge in an ecofriendly and sustainable way. This holistic
approach to crop improvement may not only resolve the upcoming food
security issues, but also make the environment greener by reducing
the chemical inputs. Plant, soil and microbe, Volume 1:
Implications in Crop Science, along with the forthcoming Volume 2:
Mechanisms and Molecular Interactions, provide detailed accounts of
the exquisite and delicate balance between the three critical
components of agronomy. Specifically, these two titles focus on the
basis of nutrient exchange between the microorganisms and the host
plants, the mechanism of disease protection and the recent
molecular details emerged from studying this multi-tropic
interaction. Together they aim to provide a solid foundation for
the students, teachers, and researchers interested in soil
microbiology, plant pathology, ecology and agronomy.
Over the past 50 years, biotechnology has been the major driving
force for increasing crop productivity. Particularly, advances in
plant genetic engineering technologies have opened up vast new
opportunities for plant researchers and breeders to create new crop
varieties with desirable traits. Recent development of precise
genome modification methods, such as targeted gene
knock-out/knock-in and precise gene replacement, moves genetic
engineering to another level and offers even more potentials for
improving crop production. The work provides an overview of the
latest advances on precise genomic engineering technologies in
plants. Topics include recombinase and engineered
nucleases-mediated targeted modification, negative/positive
selection-based homologous recombination and oligo
nucleotide-mediated recombination. Finally, challenges and impacts
of the new technologies on present regulations for genetic
modification organisms (GMOs) will be discussed.
This book details the plant-assisted remediation method,
"phytoremediation", which involves the interaction of plant roots
and associated rhizospheric microorganisms for the remediation of
soil contaminated with high levels of metals, pesticides, solvents,
radionuclides, explosives, crude oil, organic compounds and various
other contaminants. Each chapter highlights and compares the
beneficial and economical alternatives of phytoremediation to
currently practiced soil removal and burial practices.
This book presents the latest developments and recent research
trends in the field of plankton, highlighting the potential
ecological and biotechnological applications. It critically and
comprehensively discusses strain selection, growth characteristics,
large-scale culturing, and biomass harvesting, focusing on the
screening and production of high-value products from algae, and
evaluating carbon dioxide sequestration from fuel gas as a climate
change mitigation strategy. The latter areas of research are
clearly central to the sustainable development approach that is
currently attracting global attention. Over the decades, much of
the literature on has focused on the biological and ecological
aspects of phytoplankton found in freshwater, marine and brackish
water environments. However, these organisms are known to also
inhabit various other environments. More recently, there has been a
substantial shift toward the concept of sustainable development and
the "green economy" with emphasis on exploiting biological systems
for the benefit of mankind. The significance of these plankton
cannot be underestimated as they contribute approximately 40% of
the oxygen in the atmosphere. Therefore, there is potential for
exploitation of this invaluable biomass source that could lead to
significant environmental and economic benefits for man. Providing
a comprehensive outline of the most recent developments and
advances in the field of industrial applications of these plankton,
this book is an excellent reference resource for researchers and
practitioners.
Many plants produce enzymes collectively known as
ribosome-inactivating proteins (RIPs). RIPs catalyze the removal of
an adenine residue from a conserved loop in the large ribosomal
RNA. The adenine residue removed by this depurination is crucial
for the binding of elongation factors. Ribosomes modified in this
way are no longer able to carry out protein synthesis. Most RIPs
exist as single polypeptides (Type 1 RIPs) which are largely
non-toxic to mammalian cells because they are unable to enter them
and thus cannot reach their ribosomal substrate. In some instances,
however, the RIP forms part of a heterodimer where its partner
polypeptide is a lectin (Type 2 RIPs). These heterodimeric RIPs are
able to bind to and enter mammalian cells. Their ability to reach
and modify ribosomes in target cells means these proteins are some
of the most potently cytotoxic poisons found in nature, and are
widely assumed to play a protective role as part of the host
plant's defenses. RIPs are able to further damage target cells by
inducing apoptosis. In addition, certain plants produce lectins
lacking an RIP component but which are also cytotoxic. This book
focuses on the structure/function and some potential applications
of these toxic plant proteins.
The mosses (Bryophatea, Musci) are a diverse and widely distributed
group of land plants. Mosses are attractive experimental plants
because they exhibit the traditional attributes of good model
systems (Le. ease of growth & maintenance, fast generation
time, and amenable genetics) with the added advantage of a haploid
gametophyte that allowed developmental mutants to be recovered with
relative ease. In addition, mosses with the ability to tolerate
extreme environmental conditions offer realistic models for the
analysis of environmental stress-tolerance; particularly when
compared to tracheophytes such as Arabidopsis thaliana in which
these important plant phenotypes are either not clearly expressed
or entirely lacking. And, in one of the most exciting developments
in Plant Biology, efficient homologous recombination occurs in the
moss Physcomitrella patens. The ability to perform efficient
homologous recombination (Le. gene knock-outs) in P. patens is at
present unique amongst all plants and represents an extremely
powerful technique for the functional analysis of many plant genes.
Over the past 5 years, a world-wide community of moss researchers
has evolved. A highly successful "Moss" conference has been held
annually (l998-Mumbai, India; 1999-Carbondale, IL, USA;
2000-Villars, Switzerland; 200l-0kazaki, Japan; 2002-Ambleside, UK;
2003-St. Louis, MO, USA) with "Moss 2004" planned to be held in
Frieburg Germany. These conferences have been instrumental in the
creation & development of strong collaborative ties, and the
free exchange of both ideas and materials.
