“…The signal transduction mechanism by Ca 2+ not only involves the CBL–CIPK module, but also other Ca 2+ activated protein kinases (CAPK) involved in this pathway, which enable in transducing specific Ca 2+ responses. These CAPK include CDPK, CDPK‐related protein kinases (CRK), CaM activated kinases (CaMK) and Ca 2+ and CaM activated kinases (CCaMK) (Chae et al , Das and Pandey ) (Fig. ).…”

“…The CDPK protein contains N‐terminal lipid modification sites, a catalytic kinase domain with an activation loop, an autoinhibitory/junction domain, to keep the kinase inactive at basal level of Ca 2+ , and the EF‐hand containing C‐terminal to sense the Ca 2+ signatures (Hrabak et al ). The EF‐hands in the C‐terminal sense the rise in Ca 2+ concentration, bind to Ca 2+ followed by removal of inhibitory domain and activation of the kinase (Yoo and Harmon , Chae et al , Hashimoto and Kudla ). The N‐terminal lipid modification sites enable CDPKs to be targeted to the PM, ER or peroxisome (Takahashi and Ito ).…”

In a given environment, plants are constantly exposed to multitudes of stimuli. These stimuli are sensed and transduced to generate a diverse array of responses by several signal transduction pathways. Calcium (Ca ) signaling is one such important pathway involved in transducing a large number of stimuli or signals in both animals and plants. Ca engages a plethora of decoders to mediate signaling in plants. Among these groups of decoders, the sensor responder complex of calcineurin B-like protein (CBL) and CBL-interacting protein kinases (CIPKs) play a very significant role in transducing these signals. The signal transduction mechanism in most cases is phosphorylation events, but some structural role for the pair has also come to light recently. In this review, we discuss the structural nature of the sensor-responder duo; their mechanism of substrate phosphorylation and also their structural role in modulating targets. Moreover, the mechanism of complex formation and mechanistic role of protein phosphatases with CBL-CIPK module has been mentioned. A comparison of CBL-CIPK with other decoders of Ca signaling in plants also signifies the relatedness and diversity in signaling pathways. Further an attempt has been made to compare this aspect of Ca signaling pathways in different plant species to develop a holistic understanding of conservation of stimulus-response-coupling mediated by this Ca -CBL-CIPK module.

“…ABA is a central regulator of many plant responses to environmental stresses, particularly osmotic stresses [110][111][112][113], and hence one of the most studied topics in the response of plants to abiotic stress, especially water stress, is ABA signaling and ABA-responsive genes. ABA synthesis is one of the fastest responses of plants to abiotic stress, triggering ABA-inducible gene expression [114] and causing stomatal closure, thereby reducing water loss via transpiration [115], and eventually restricting cellular growth.…”

“…In maize, at least 10 viviparous mutants have been identified, most of which (vp2, vp5, vp7, vp9, w3, y3, and y9) were blocked in the biosynthesis of the carotenoid precursors for de novo ABA synthesis; in rice (Oryza sativa), four phs mutants, defective in phytoene desaturase (OsPDS), f-carotene desaturase (OsZDS), carotenoid isomerase (OsCR-TISO), and lycopene b-cyclase (b-OsLCY), were found to affect the biosynthesis of carotenoid precursors of ABA [117]. ABA signaling can also be very fast without involving transcriptional activity; a good example is the control of the stomatal aperture by ABA through the biochemical regulation of ion and water transport processes [112]. ABA is a key phytohormone in plant responses to water deficit; therefore, elucidation of the mechanism of ABA signal transduction significantly contributes to the establishment of a suitable strategy for elevation of plant tolerance to abiotic stresses [118].…”

“…Elucidating the function of proteins expressed by genes in stress-tolerant and -susceptible plants would advance our understanding of plant adaptation and tolerance to environmental stresses, but also may provide important information for designing new strategies for crop improvement [112]. Protein kinases and protein phosphatases often act in tandem to perform the phosphorylation and dephosphorylation process, and much work is ongoing to unravel the molecular mechanisms involved in the expression of several of the large gene families that encode protein kinases and phosphatases involved in stress signaling in plants.…”

Abiotic stress responses are of the utmost importance for plants because they cannot survive unless they are able to cope with environmental changes, such as high and low temperatures, drought, flooding, salinity, freezing, change in pH, strong light, UV, and heavy metals. Plants respond to various stresses at different levels, including molecular and cellular levels, as well as by modifying their metabolomes. Hence, studies on plant responses to stresses can be conducted at any of these levels to provide an understanding of the mechanisms involved. The present chapter focuses on the metabolomic approach to understand the responses of plants to different abiotic stresses, which can then be utilized to evolve strategies to combat such stress. Osmoprotectant metabolites, such as proline, glycine betaine, and polyamines, as well as carbohydrates, play important roles in the protection of plants against osmotic disbalances due to abiotic stresses. In addition, oxidative stresses are also overcome by an array of antioxidants, such as phenols, ascorbate, carotenoids, and a-tocopherol, as well as antioxidative enzymes. Signaling cascades activated during abiotic stresses lead to overexpression of protein kinases and stress proteins, and also involve molecules such as jasmonic acid and salicylic acid. Protein kinases and protein phosphatases that are encoded by large gene families often act in tandem to perform the phosphorylation and dephosphorylation leading to their activation and inactivation involved in stress signaling in plants. Analysis of microRNAs and transcriptomes has provided sufficient understanding of the gene expression levels during periods of stress. Hence, taken together, all these results can be utilized for identifying genes and/or metabolites overexpressed in tolerant species during periods of stress, and can be utilized to achieve higher tolerance and survivability during stresses. 727
