    The plant cytoskeleton takes center stage in abiotic stress responses and resilience
    (John Wiley & Sons, 2023) Kumar, Sunil; Jeevaraj, Theboral; Yunus, Mohd Hadi; Chakraborty, Subhra; Chakraborty, Niranjan
    Stress resilience behaviours in plants are defensive mechanisms that develop under adverse environmental conditions to promote growth, development and yield. Over the past decades, improving stress resilience, especially in crop species, has been a focus of intense research for global food security and economic growth. Plants have evolved specific mechanisms to sense external stress and transmit information to the cell interior and generate appropriate responses. Plant cytoskeleton, comprising microtubules and actin filaments, takes a center stage in stress-induced signalling pathways, either as a direct target or as a signal transducer. In the past few years, it has become apparent that the function of the plant cytoskeleton and other associated proteins are not merely limited to elementary processes of cell growth and proliferation, but they also function in stress response and resilience. This review summarizes recent advances on the role of plant cytoskeleton and associated proteins in abiotic stress management. We provide a thorough overview of the mechanisms that plant cells employ to withstand different abiotic stimuli such as hypersalinity, dehydration, high temperature and cold, among others. We also discuss the crucial role of the plant cytoskeleton in organellar positioning under the influence of high light intensity.

    Plant Tolerance to Individual and Concurrent Stresses
    (Springer, 2017) Senthil-Kumar, Muthappa
    This book focuses on multiple plant stresses and the molecular basis of adaptation, addressing the molecular mechanism and adaptation for both abiotic and biotic stresses. Ensuring the yield of crop plants grown under multiple individual and/or combined stresses is essential to sustaining productivity. In this regard, the development of broad-spectrum stress-tolerant plants is important. However, to date information has largely been compiled only on the individual stress tolerance mechanisms, and the mechanisms behind plants’ tolerance to two or more individual or simultaneous stresses are not fully understood. Especially combinatorial stress, a new stress altogether, has only recently been made the object of systematic study. Now several research groups around the world have begun exploring the concurrent stress tolerance mechanisms under both biotic and abiotic stress combinations. This book presents contributions from various experts, highlighting the findings of their multiple individual and concurrent stress tolerance dissection studies.

    Jasmonates: Emerging players in controlling temperature stress tolerance
    (Frontiers Media S.A., 2016) Sharma, Manvi; Laxmi, Ashverya
    The sedentary life of plants has forced them to live in an environment that is characterized by the presence of numerous challenges in terms of biotic and abiotic stresses. Phytohormones play essential roles in mediating plant physiology and alleviating various environmental perturbations. Jasmonates are a group of oxylipin compounds occurring ubiquitously in the plant kingdom that play pivotal roles in response to developmental and environmental cues. Jasmonates (JAs) have been shown to participate in unison with key factors of other signal transduction pathway, including those involved in response to abiotic stress. Recent findings have furnished large body of information suggesting the role of jasmonates in cold and heat stress. JAs have been shown to regulate C-repeat binding factor (CBF) pathway during cold stress. The interaction between the integrants of JA signaling and components of CBF pathway demonstrates a complex relationship between the two. JAs have also been shown to counteract chilling stress by inducing ROS avoidance enzymes. In addition, several lines of evidence suggest the positive regulation of thermotolerance by JA. The present review provides insights into biosynthesis, signal transduction pathway of jasmonic acid and their role in response to temperature stress.
