A comprehensive review of stress signaling in plants using genomics and functional genomic approaches

Improving agricultural production and meeting the needs of a rapidly growing global population requires crop systems capable of overcoming environmental stresses. Understanding the role of different signaling components in plant stress regulation is vital to developing crops which can withstand abiotic and biotic stresses without loss of crop yield and productivity. Emphasizing genomics and functional genomic approaches, Protein Kinases and Stress Signaling in Plants is a comprehensive review of cutting-edge research on stress perception, signal transduction, and stress response generation.

Detailed chapters cover a broad range of topics central to improving agricultural production developing crop systems capable of overcoming environmental stresses to meet the needs of a rapidly growing global population. This book describes the field of protein kinases and stress signaling with a special emphasis on functional genomics. It presents a highly valuable contribution in the field of stress perception, signal transduction and generation of responses against one or multiple stress signals.

This timely resource:

• Summarizes the role of various kinases involved in stress management 
• Enumerates the role of TOR, GSK3-like kinase, SnRK kinases in different physiological conditions
• Examines mitogen-activated protein kinases (MAPKs) in different stresses
• Describes the different aspects of calcium signaling under different stress conditions
• Examines photo-activated kinases (PAPKs) in varying light conditions
• Briefs the presence of tyrosine kinases in plants
• Highlights the cellular functions of receptor]like protein kinases (RLKs)
• Possible implication of these kinases in developing stress tolerant crops

Protein Kinases and Stress Signaling in Plants: Functional Genomic Perspective is an essential resource for researchers and students in the fields of plant molecular biology and signal transduction, plant responses to stress, plant cell signaling, plant protein kinases, plant biotechnology, transgenic plants and stress biology.

Introduction

Living organisms are constantly exposed to environmental changes. Different organisms adapt and respond differently to the adverse conditions (Bray 1997; Kozlowski 1997; Sakai and Larcher 2012; Bleuven and Landry 2016). One of the key features that distinguish plants from animals is that the former are sessile in nature and require more efficiently governed genetic regulation to cope with unfavorable environmental conditions. Hence, during evolution, plants have developed intricate mechanisms to face these environmental challenges to some extent. Plants’ responses toward environmental stresses are multigenic and are governed by complex signaling molecules working in an orchestrated manner (Nongpiur et al. 2012). Various ‐omics approaches, including genomics, transcriptomics, proteomics and metabolomics, have been utilized to understand the signaling machinery operative under abiotic stresses. These studies reveal that tolerant plants withstand the extremes of environment in an adaptive manner, by re‐adjusting the major signaling and metabolic pathways to maintain cellular homeostasis (Ward and Thompson 2012; Ding et al. 2013; Soni et al. 2015). The response toward stresses involves complex molecules, wisely regulated at distinct checkpoints. Environmental changes are perceived by receptors such as histidine kinases (HKs), hormone receptors, G‐protein coupled receptors (GPCR), receptor kinases, transporters, antiporters, and tyrosine or serine/threonine kinases (Kacperska 2004; Osakabe et al. 2013; Zargar 2018). These activated receptors trigger downstream cascade by activating signaling molecules like Ca²⁺, ROS (reactive oxygen species), and other adapter molecules, which ultimately leads to the initiation of a series of post‐translational protein modification events (Nishida and Gotoh 1993; Lee et al. 2007). These modifications can result in the activation of effector proteins, which function directly in the alleviation of the effects of the stress. The modifications can also stimulate the regulation of transcription factors, which modulates the expression of stress related genes to combat the detrimental effect of the environmental extremes (Jaspers and Kangasjärvi 2010; Sinha et al. 2011; Zhu 2016). Though a certain level of overlap does exist in the responses to different environmental constraints, these responses are usually distinct for each environmental stress (Zhu 2001; Fujita et al. 2006). More than one type of stress can turn “on” similar set of genes and thus participate in the crosstalk for stress signaling (Fujita et al. 2009; Gupta et al. 2016).

The two‐component system (TCS) is known to play a significant role in regulating various biological processes in both prokaryotes and eukaryotes, including higher plants. However, in eukaryotes, animals do not possess TCS regulatory system. TCS is a signal transduction pathway, which primarily evolved for the perception and transduction of extracellular signals. This signaling mechanism operates by the His‐Asp phosphorelay. As the name suggests, the simplest form of TCS involves two major components for signaling; one membrane bound sensory HK and the other ones is its cognate response regulator (RR). Signal is perceived by the HK, which auto‐phosphorylates at a conserved histidine residue and then transfers this phosphoryl group to a conserved aspartate residue on the RR, which in turn stimulates a response. This kind of TCS, designated as prototypical TCS, has been identified only in prokaryotes and has been shown to govern distinct cellular processes such as chemotaxis, quorum sensing, and osmotic response (Aizawa et al. 2000; Mitrophanov and Groisman 2008). Schematic diagram, for how the TCS signaling proceeds, is given in Figure 1.1. A more complex form of TCS, designated as the multistep phosphorelay (MSP), is found in both prokaryotes and eukaryotes. The MSP possesses an additional shuttle protein to communicate signal between HK to the RR. This additional shuttle/adapter molecule is known as HPT (histidine containing phosphotransfer protein). In addition to the HPTs, the HKs of MSP are more complex than the prototyp...
