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.

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.

Abiotic stresses such as high temperature, low-temperature, drought and salinity limit crop productivity worldwide. Understanding plant responses to these stresses is essential for rational engineering of crop plants. In Arabidopsis, the signal transduction pathways for abiotic stresses, light, several phytohormones and pathogenesis have been elucidated. A significant portion of plant genomes (Arabidopsis and rice were mostly studied) encodes for proteins involves in signaling such as receptor, sensors, kinases, phosphatases, transcription factors and transporters/channels. Despite decades of physiological and molecular effort, knowledge pertaining to how plants sense and transduce low and high temperature, low-water availability (drought), water-submergence, microgravity and salinity signals is still a major question for plant biologist. One major constraint hampering our understanding of these signal transduction processes in plants has been the lack or slow pace of application of molecular genomic and genetics knowledge in the form of gene function. 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 not only one gene family but 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. Therefore, in this e-Book, we intend to incorporate the contribution from leading plant biologists to elucidate several aspects of stress signaling by functional genomics approaches.

Sequencing projects have revealed the presence of at least several hundred receptor kinases in a typical plant genome. Receptor kinases are therefore the largest family of primary signal transducers in plants, and their abundance suggests an immense signaling network that we have only just begun to uncover. Recent research findings indicate that individual receptor kinases fulfill important roles in growth and development, in the recognition of pathogens and symbionts or, in a few examples, in both growth and defense. This volume will focus on the roles of receptor kinases, their signaling pathways, and the ways in which these important signaling proteins are regulated.

Environmental insults such as extremes of temperature, extremes of water status as well as deteriorating soil conditions pose major threats to agriculture and food security. Employing contemporary tools and techniques from all branches of science, attempts are being made worldwide to understand how plants respond to abiotic stresses with the aim to help manipulate plant performance that will be better suited to withstand these stresses. This book on abiotic stress attempts to search for possible answers to several basic questions related to plant responses towards abiotic stresses. Presented in this book is a holistic view of the general principles of stress perception, signal transduction and regulation of gene expression. Further, chapters analyze not only model systems but extrapolate interpretations obtained from models to crops. Lastly, discusses how stress-tolerant crop or model plants have been or are being raised through plant breeding and genetic engineering approaches. Twenty three chapters, written by international authorities, integrate molecular details with overall plant structure and physiology, in a text-book style, including key references.
