Book Summary: To meet the challenge of feeding ever increasing human population, efficient, economical and environment friendly disease control methods are required. Pests are responsible for heavy crop losses and reduced food supplies, poorer quality of agricultural products, economic hardship for growers and processor.

Generally, chemical control methods are neither always economical nor are they effective and may have associated unwanted health, safety and environmental risks. Biological control involves use of beneficial microorganism to control plant pathogens and diseases they cause and offers an environmental friendly approach to the effective management of plant diseases.

This book provides a comprehensive account of interaction of host and its pathogens, induced host resistance, development of biological control agents for practical applications, the underlying mechanism and signal transduction.

The book is useful to all those working in academia or industry related to crop protection. Book Summary: Abiotic stress cause changes in soil-plant-atmosphere continuum and is responsible for reduced yield in several major crops.

Therefore, the subject of abiotic stress response in plants - metabolism, productivity and sustainability - is gaining considerable significance in the contemporary world. Prolonged exposure to these abiotic stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to tolerate these stresses by upregulation of osmolytes, osmoprotectants, and enzymatic and non-enzymatic antioxidants, etc.

This volume deals with abiotic stress-induced morphological and anatomical changes, abberations in metabolism, strategies and approaches to increase salt tolerance, managing the drought stress, sustainable fruit production and postharvest stress treatments, role of glutathione reductase, flavonoids as antioxidants in plants, the role of salicylic acid and trehalose in plants, stress-induced flowering.

The role of soil organic matter in mineral nutrition and fatty acid profile in response to heavy metal stress are also dealt with. Proteomic markers for oxidative stress as a new tools for reactive oxygen species and photosynthesis research, abscisic acid signaling in plants are covered with chosen examples. Stress responsive genes and gene products including expressed proteins that are implicated in conferring tolerance to the plant are presented.

Thus, this volume would provides the reader with a wide spectrum of information including key references and with a large number of illustrations and tables.

Book Summary: This book summarizes our current knowledge on belowground defence strategies in plants by world-class scientists actively working in the area. The volume includes chapters covering belowground defence to main soil pathogens such as Fusarium, Rhizoctonia, Verticillium, Phytophthora, Pythium and Plasmodiophora, as well as to migratory and sedentary plant parasitic nematodes.

In addition, the role of root exudates in belowground plant defence will be highlighted, as well as the crucial roles of pathogen effectors in overcoming root defences.

Finally, accumulating evidence on how plants can differentiate beneficial soil microbes from the pathogenic ones will be covered as well. Better understanding of belowground defences can lead to the development of environmentally friendly plant protection strategies effective against soil-borne pathogens which cause substantial damage on many crop plants all over the world.

The book will be a useful reference for plant pathologists, agronomists, plant molecular biologists as well as students working on these and related areas. Book Summary: Applied Plant Biotechnology for Improvement of Resistance to Biotic Stress applies biotechnology insights that seek to improve plant genomes, thus helping them achieve higher resistance and optimal hormone signaling to increase crop yield.

The book provides an analysis of the current state-of-the-art in plant biotechnology as applied to improving resistance to biotic stress. Signalling Components Upstream of SA To elucidate the SA signalling pathways in Arabidopsis, many genetic screens have been conducted to identify genes that are involved in SA synthesis and signal transduction.

Figure 2. Conclusions Although great strides have been made in understanding the SA signalling pathway over the last two decades, much still remains to be elucidated. References Alfano, J.

This chapter covers the recent progress in our understanding of the SA biology in plants, especially the signaling pathways and mechanisms by which SA performs its role as defense inducer are highlighted. The topics related to SA signal transduction covered here include 1 general biological roles played by SA; 2 biosynthesis, storage and translocation of SA; 3 oxidative SA metabolisms regulating the SA actions; 4 roles of reactive oxygen species and calcium ion in SA signaling paths; 5 the link between oxidative burst and other signaling paths; and 6 regulation of gene expression.

Lastly, we illustrated the key signaling networks that coordinately lead to both early and late phases of SA-induced gene expression. Unable to display preview. Download preview PDF.
