“…But there were still a few BdCDPK genes which might execute their function continuously. Interestingly, it exhibited a similar expression pattern in the B. distachyon seedlings subjected to salt, drought and oxidative stresses, which was consisted with the previous reports that many CDPKs were involved in both salt and drought stresses, and they positively mediated tolerance to these stresses by protecting plants from reactive oxygen species (ROS) damage, with the uncontrolled generation of ROS being a common feature of these stresses [80,[89][90][91]. Notably, a set of genes (BdCDPK09, 10, 11, 12, 13, and 20) were up-regulated 0-12 h post treatment with NaCl and PEG, while they were up-regulated 12-24 h post treatment with heat stress, implying these BdCDPKs might play different roles in response to these stresses.…”

Background: Ca 2+ played as a ubiquitous secondary messenger involved in plant growth, development, and responses to various environmental stimuli. Calcium-dependent protein kinases (CDPK) were important Ca 2+ sensors, which could directly translate Ca 2+ signals into downstream phosphorylation signals. Considering the importance of CDPKs as Ca 2+ effectors for regulation of plant stress tolerance and few studies on Brachypodium distachyon were available, it was of interest for us to isolate CDPKs from B. distachyon. Results: A systemic analysis of 30 CDPK family genes in B. distachyon was performed. Results showed that all BdCDPK family members contained conserved catalytic Ser/Thr protein kinase domain, autoinhibitory domain, and EF-hand domain, and a variable N-terminal domain, could be divided into four subgroup (I-IV), based upon sequence homology. Most BdCDPKs had four EF-hands, in which EF2 and EF4 revealed high variability and strong divergence from EF-hand in AtCDPKs. Synteny results indicated that large number of syntenic relationship events existed between rice and B. distachyon, implying their high conservation. Expression profiles indicated that most of BdCDPK genes were involved in phytohormones signal transduction pathways and regulated physiological process in responding to multiple environmental stresses. Moreover, the co-expression network implied that BdCDPKs might be both the activator and the repressor involved in WRKY transcription factors or MAPK cascade genes mediated stress response processes, base on their complex regulatory network. Conclusions: BdCDPKs might play multiple function in WRKY or MAPK mediated abiotic stresses response and phytohormone signaling transduction in B. distachyon. Our genomics analysis of BdCDPKs could provide fundamental information for further investigation the functions of CDPKs in integrating Ca 2+ signalling pathways in response to environments stresses in B. distachyon.

“…To adapt to water-deficit conditions, plants regulate various cellular processes, including transcription, translation, and post-translational modification. Protein phosphorylation via plant kinases is a post-translational modification process, and it plays an important role in ABA signaling and the drought stress responses (Bundo and Coca, 2017;Yang et al, 2017). Several stress-related kinases have been identified and functionally characterized; nevertheless, the precise mechanisms by which plants respond to stress remain unclear.…”

Protein phosphorylation and dephosphorylation are important mechanisms that regulate many cellular processes. Protein kinases usually function in the regulation of the stress responses by adjusting activity via phosphorylation of target proteins. Here, we isolated CaAIMK1 (Capsicum annuum ABA Induced MAP Kinase 1) from the pepper leaves that had been subjected to drought stress. CaAIMK1 transcripts were induced by drought, abscisic acid (ABA), high salinity, and H 2 O 2 ; further, the CaAIMK1-Green fluorescent protein localized in the nucleus and cytoplasm. We performed genetic studies using CaAIMK1-silenced pepper plants and CaAIMK1-overexpressing (OX) Arabidopsis plants. CaAIMK1-silenced pepper plants showed a drought-sensitive phenotype characterized by altered ABA signaling, including low leaf temperatures, and large stomatal apertures. CaAIMK1-OX plants exhibited a contrasting drought-tolerant phenotype characterized by decreased levels of transpirational water loss and increased expression levels of Arabidopsis stress-related genes. In CaAIMK1 K32N-OX transgenic Arabidopsis plants, sensitivity to ABA and drought was restored. Collectively, these results demonstrate that CaAIMK1 positively regulates the drought stress responses via an ABA-dependent pathway.

“…One such annexin, OsANN1, functions as an ATPase with the ability to bind Ca 2+ and regulate the inflow and efflux of Ca 2+ ions. Through the interaction with OsCDPK10 , a protein kinase, OsANN1 confers abiotic stress tolerance via antioxidant accumulation [ 267 ]. Further, through yeast two-hybrid system analyses, it was demonstrated that OsANN1 interacts with OsCDPK24 and, therefore, regulates abiotic stress responses [ 268 ].…”

Climate change-induced abiotic stress results in crop yield and production losses. These stresses result in changes at the physiological and molecular level that affect the development and growth of the plant. Reactive oxygen species (ROS) is formed at high levels due to abiotic stress within different organelles, leading to cellular damage. Plants have evolved mechanisms to control the production and scavenging of ROS through enzymatic and non-enzymatic antioxidative processes. However, ROS has a dual function in abiotic stresses where, at high levels, they are toxic to cells while the same molecule can function as a signal transducer that activates a local and systemic plant defense response against stress. The effects, perception, signaling, and activation of ROS and their antioxidative responses are elaborated in this review. This review aims to provide a purview of processes involved in ROS homeostasis in plants and to identify genes that are triggered in response to abiotic-induced oxidative stress. This review articulates the importance of these genes and pathways in understanding the mechanism of resistance in plants and the importance of this information in breeding and genetically developing crops for resistance against abiotic stress in plants.
