The regulation of the phosphorylation/dephosphorylation process, resulting in “cellular switches” that monitor normal plant physiology, growth and development, has immense potential in crop systems. With much of the information in the nascent stages, coming largely from Arabidopsis and rice particularly, the use of cell biology, genetic screens, biochemical approaches aided by an omics approach should help unravel the detail functional information available about signaling pathways in plants. The regulation could be exploited to develop crop varieties better equipped to handle changing environments and enhance agricultural productivity. In the post-genomic era, one of the major challenges is investigation and understanding of multiple genes and gene families regulating a particular physiological and developmental aspect of plant life cycle. One of the important physiological processes is regulation of stress response, which leads to adaptation or adjustment in response to adverse stimuli. With the holistic understanding of the signaling pathways involving phosphatases, one gene family or multiple genes or gene families, plant biologist can lay a foundation for designing and generating future crops, which can withstand the higher degree of environmental stresses. Especially abiotic stresses, which are the major cause of crop loss throughout the world without losing crop yield and productivity. This book incorporates the contributions from leading plant biologists in the field of stress-mediated dephosphorylation by phosphatases as an important task to elucidate the aspects of stress signaling by functional genomic approaches.

Soybean (Glycine max) and rice (Oryza sativa) are the most important crops cultivated worldwide. The productivity of both crops is severely limited due to drought stresses. Abscisic acid (ABA) signaling is one of the crucial phytohormones which acts as the signaling mediator in different environmental stress for adaptive response of plants. In this study, functional characterization of abscisic acid-activated protein kinaselike kinase 1 (AALK1), and low molecular weight protein tyrosine phosphatase (LMWPTP) were studied by developing gain-of-function and loss-of-function phenotypes by transgenesis. Physiological response of AALK1 showed that AALK1 modulates the drought stress response ins soybean plants. The study has demonstrated several key genes are differentially expressed control, and aalk1-RNAi silenced lines under drought treatment. The AALK1 overexpression lines enhanced the transcription of other ABA-responsive genes, indicating that the AALK1 is a positive regulator of ABA-mediated stress signaling pathways in soybean. The phylogenetic analysis and domain analysis also supports that AALK1 is abscisic acid-activated protein kinase and has a role in drought response. Phenotype analysis of LMWPTP in rice showed that transgenic overexpression of LMWPTP exhibited significantly improved drought tolerance in comparison to RNAi silencing and control plants, which indicates that LMWPTP modulates the drought stress tolerance of rice plants. Further, 5 putative tyrosine phosphorylated proteins were detected through immunoblotting and identified by mass spectrometry. Some of these tyrosine phosphorylated proteins are likely to be target proteins of LMWPTP. Together, the present findings strengthen the knowledge about the functional role of AALK1 and LMWPTP, which can be utilized as a promising gene-based molecular marker in transgenic breeding for generating crop plants with improved drought tolerance which ultimately improve the grain yields.

Understand the impact of climate change on plant growth with this timely introduction Climate change has had unprecedented consequences for plant metabolism and plant growth. In botany, adverse effects of this kind are called plant stress conditions; in recent years, the plant stress conditions generated by climate change have been the subject of considerable study. Plants have exhibited increased photosynthesis, increased water requirements, and more. There is an urgent need to understand and address these changes as we adapt to drastic changes in the global climate. Global Climate Change and Plant Stress Management presents a comprehensive guide to the effects of global climate change on plants and plant metabolism. It introduces and describes each climate change-related condition and its components, offering a detailed analysis of the resulting stress conditions, the environmental factors which ameliorate or exacerbate them, and possible solutions. The result is a thorough, rigorous introduction to this critical subject for the future of our biome.
