Genomics And Molecular Genetics Of Plant Nematode Interactions

This book reviews developments in the molecular biology of plant-nematode interactions that have been driven by the application of genomics tools. The book will be of interest to postgraduate students and to researchers with an interest in plant nematology and/or plant pathology more generally. A series of introductory chapters provide a biological context for the detailed reviews of all areas of plant-nematode interactions that follow and ensure that the bulk of the book is accessible to the non-specialist. A final section aims to show how these fundamental studies have provided outputs of practical relevance.

In 1992 a Concerted Action Programme (CAP) was initiated by Peter Sijmons with the purpose of intensifying collaborations between 16 European laboratories working on plant-parasitic nematodes. The four-year programme entitled `Resistance mechanisms against plant-parasitic nematodes' focused on molecular aspects of the interaction between sedentary nematodes and plants on the model system Arabidopsis and on novel resistance strategies. Funding was provided mainly for exchange visits between collaborating laboratories and for the organization of annual meetings. During the last annual meeting which was held in May 1996 in Toledo, Spain, Carmen Fenoll initiated the production of this volume. The book presents a series of up-to-date reviews, each written by one of the participating laboratories, which include the scientific progress achieved in the frame of this CAP but are by no means limited in scope to this work.

The plant-parasitic nematodes Pratylenchus penetrans and Heterodera glycines are of major economic importance worldwide. Here, we present a survey of over 1,900 expressed sequence tags (ESTs) for P. penetrans and of almost 22,000 ESTs for H. glycines. Furthermore, we conducted microarray expression profiling for over 6,800 H. glycines genes throughout the life cycle. We identified over 600 H. glycines genes that encode secretory proteins and provide microarray data for all known H. glycines parasitism genes as well as for H. glycines genes with similarity to known plant and microbe sequences. In order to extend these studies, we have identified soybean and Phytophthora sojae sequences that consistently cross-hybridize in microarray analyses with probes derived from H. glycines mRNA and identified H. glycines ESTs potentially responsible for this cross-hybridization. The impact of these findings on our understanding of host-parasite relationships is discussed. Furthermore, we showed that H. glycines parasitism proteins with nuclear localization signals are imported into plant cell nuclei. Using the same approach, we also confirmed the predicted nuclear localization for the cyst nematode-responsive soybean transcription factor GmEREBP1.

Plant-parasitic nematodes are among the most destructive plant pathogens, causing enormous losses to agronomic crops worldwide. This book provides an up-to-date review of research related to two of the most important nematode pests, root-knot and cyst nematodes. Chapters cover early plant-nematode interactions, identification of nematode proteins important in the establishment of nematode feeding sites, and classification of biochemical and signaling pathways significant in the development of specialized feeding sites in the host. The cellular and subcellular structures essential for the parasitic interaction are examined by light and electron microscopy. Modern techniques of gene expression analyses and genomic sequencing are poised to provide an even greater wealth of information to researchers, enabling them to develop and examine natural and manmade mechanisms of resistance to this important plant pest.

Plant parasitic nematodes are a main pest to crops. For ex am pie, the root-knot nematodes belonging to the genus Meloidogyne are worldwide in their distribution and attack almost every type of crop, causing considerable losses of yield and affecting quality of produce. The cyst nematodes within the genera Globodera and Heterodera constitute a major group of plant pathogens in many countries throughout the world, suppressing yields of potato, sugar beet, soybean and cereals. Several nematodes such as longidorids and trichodorids are implicated in the transmission of numerous plant viruses. Many others cause constraints to agricultural production either locally or on large areas. However, despite their economic importance (they account for worldwide crop reduction in excess of 10%), plant parasitic nematodes are still poorly understood, because most of them are obligate parasites of roots. Environmental concerns over the agricultural use of pesticides demand the development of alternative measures to control them. To achieve environmentally sound control, knowledge of the basic biology of nematodes must be expanded. Important research areas include understanding the molecular bases for pathogenicity, the molecular mechanisms of the host parasite interactions and the genetic bases for population fluctuations. The workshop has, for the first time, brought together an international group of researchers using molecular approaches to study plant parasitic nematodes and their host responses.

Plants are an indispensable part of human and animal lives for nutrition and health. But pests, diseases and abiotic stress adversely affect crop yield, which ultimately places significant pressure on society to provide food to an increasing population. Moreover, it also encourages increased chemical/pesticide usage on crops, which we see in the biomagnification of toxic and hazardous compounds polluting water bodies, soil and the environment. This condition will continue to worsen in the future due to the resistance-acquiring ability of pathogens against plant defense and chemical treatments. In addition, environmental disturbances and consumer health issues are being reported more promptly than before due to intensive use of pesticides in food production. Plant diseases affect our daily lives, as the use of insecticides and pesticides has become part of our food chain. As a result, precise disease diagnosis and management is crucial in order to avoid huge losses in plant production and related commodities. Accurate detection, precise diagnosis and proper management can play a significant role in keeping plants free from pathogens. In this book, scientists, researchers and scholars share their research knowledge, offering a valuable resource for understanding plant diseases, pathogen interaction and responses to stress through an omics perspective, contributing to further advancements in the field Diseases in plants may be caused by various factors, such as viruses, bacteria, fungi and abiotic stress. Disease causes low crop yield, production of poor-quality fruits and grains, and deficiency of nutrients, which have a direct impact on human and animal health. A genomics-based approach can be applied to disease diagnosis; disease outbreak; evolution of plant and pathogen genome for disease outbreak in relation to climate change; and development of long-term strategies for plant health and defense. This book presents an overview of omics technologies and approaches used to understand: 1) the relation between plants and their environment in terms of diseases 2) responses to abiotic stress 3) the genomics of plant–pathogen interaction 4) herbicide-resistance mechanisms 5) the epigenetics of plant–pathogen interaction 6) gene regulation during abiotic stress response 7) the oxidative stress response

Fully integrated and comprehensive in its coverage, Root Genomics and Soil Interactions examines the use of genome-based technologies to understand root development and adaptability to biotic and abiotic stresses and changes in the soil environment. Written by an international team of experts in the field, this timely review highlights both model organisms and important agronomic crops. Coverage includes: novel areas unveiled by genomics research basic root biology and genomic approaches applied to analysis of root responses to the soil environment. Each chapter provides a succinct yet thorough review of research.
