Plant Roots


Book Description

The root system is a vital part of the plant and therefore understanding roots and their functioning is key to agricultural, plant and soil scientists. In Plant Roots Professor Peter Gregory brings together recent developments in techniques and an improved understanding of plant and soil interactions to present a comprehensive look at this important relationship, covering: Root response to, and modification of, soils Genetic control of roots’ responses to the environment Use of modern techniques in imaging, molecular biology and analytical chemistry Practical exploitation of root characters This book will be a vital tool for plant, crop, soil and agricultural scientists, plant physiologists, environmental scientists, ecologists and hydrologists. It will be a valuable addition to libraries in universities, agricultural colleges and research establishments where these subjects are studied and taught.




Biocontrol Potential and its Exploitation in Sustainable Agriculture


Book Description

Plant based biotechnology has come to represent a means of mitigating the problems of global food security in the twenty-first century. Products and processes in agriculture are increasingly becoming linked to science and cutting edge technology, to enable the engineering of what are in effect, designer plants. One of the most successful , non-chemical approaches to pest management and disease control is biological control, which seeks a solution in terms of using living organisms to regulate the incidence of pests and pathogens, providing a natural control' while still maintaining the biological balance with the ecosystem. This volume, (the first of two), addresses the different types of biocontrol for different pests, namely, crop diseases, weeds and nematodes, and details the biology of both the pest and its enemies, which is vital for efficient use of biological control. The book has numerous contributors who are authorities in their fields, and would be an asset to those who have interest in sustainable agriculture and crop productivity.




Treetops at Risk


Book Description

Forest canopies not only support high terrestrial biodiversity but also represent a critical interface between the atmosphere and the earth. They provide goods and services to support diverse human communities and offer opportunities to explore sustainable use of these resources for many generations of local livelihoods. Forest canopies are important carbon sequestration units, and in this sense, serve as climate control for the planet. Canopies are important energy production centers for the planet, and serve as the basis for many food chains. The canopy can also act as a hook for education outreach and conservation, inspiring ecotourism through recreation and other sustainable uses such as treetop walks, zip lines, and birding. Despite these critical services provided by forest canopies, almost no dedicated research in the treetops was initiated until as recently as the late 1970s when single rope techniques were developed by mountaineering professionals and adapted for use in the canopy. Subsequently, an array of canopy access tools was designed in the 1980s and early 1990s that have opened up this “eighth continent” for global exploration and discovery. This volume uses the major findings of the 5th international canopy conference as a platform for organization, but it does not mimic the sessions and presentations of the conference itself. Instead, it builds on the important themes that emerged from the conference and solicits articles that represent future priorities and advancements for canopy science in the next decade. Despite the global efforts of hundreds of forest scientists over the past 3 decades, forests are degrading at an accelerated rate and biodiversity is increasingly threatened by human activities. Given these trends - despite the very best efforts of the world’s best scientists - other approaches must be taken. This volume summarizes the issue of “treetops at risk” and assembles a global authorship to examine past accomplishments and future initiatives critical in forest conservation.




Understanding Host-Microbiome Interactions - An Omics Approach


Book Description

This book offers up-to-date information on different microbiomes, their community composition and interactive functions with the host, bringing together information from diverse research reports to provide an overview of the rapid developments in meta-omics technologies. It is a valuable resource for scientists, researchers, postgraduate and graduate students interested in understanding the impact and importance of next generation sequencing technologies on different hosts and their microbiomes.




Flowering Plants · Dicotyledons


Book Description

This encyclopedia contains a comprehensive treatment of the taxonomy of the families and genera of ferns and seed plants. The present volume, the fifth in this series, deals with three major groups of dicotyledons, the Capparales, Malvales, and Non-betalain Caryophyllales.







Nematode Interactions


Book Description

Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.
