Physiology And Molecular Biology of Plants

This book covers crop stress management with potential implications for crop production induced by Arbuscular mycorrhizal fungi (AMF). It provides new insights into our understanding of the mechanisms of AMF-mediated growth regulation and stress tolerance covering the most recent biochemical, physiological, molecular, environmental and ecological studies. Focusing on various physiological and molecular mechanisms induced by AMF to enhance tolerance to different stresses, each environmental constraint is discussed in an individual dedicated chapter. Moreover, the book provides not only updated information with new insights and perspectives but also several new topics, such as comprehensive discussion on biotic stressors, the potential role of elevated CO2, hormones, and signal molecules in stress perception, signal transduction and subsequent stress tolerance. The book also discusses the potential implications of AMF for sustainable crop production in the context of climate change.

Metabolic Adaptations in Plants during Abiotic Stress covers a topic of past, present and future interest for both scientists and policy makers as the global challenge of climate change is addressed

This book offers an overview of salt stress, which has a devastating effect on the yields of various agricultural crops around the globe. Excessive salts in soil reduce the availability of water, inhibit metabolic processes, and affect nutrient composition, osmotic balance, and hydraulic conductivity. Plants have developed a number of tolerance mechanisms, such as various compatible solutes, polyamines, reactive oxygen species and antioxidant defense mechanisms, ion transport and compartmentalization of injurious ions.

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.
