“…The SnRK2 kinases were identified in every plant studied. Ten members of the SnRK2 family are encoded by the Arabidopsis as well as rice and sorghum genomes (Boudsocq et al, 2004;Kobayashi et al, 2004;Li et al, 2010). Eleven SnRK2s have been identified in maize (Huai et al, 2008), and some SnRK2 representatives were described for tobacco (Kelner et al, 2004), wheat (Anderberg and Walker-Simmons, 1992;Holappa and Walker-Simons, 1995;Mao et al, 2010;Zhang et al, 2010bZhang et al, , 2011, soybean (Monks et al, 2001), fava bean (Li and Assmann, 1996;Li et al, 2000), and algae (Davies et al, 1999;Gonzalez-Ballester et al, 2008).…”

The SnRK2 family members are plant-specific serine/threonine kinases involved in plant response to abiotic stresses and abscisic acid (ABA)-dependent plant development. SnRK2s have been classed into three groups; group 1 comprises kinases not activated by ABA, group 2 comprises kinases not activated or activated very weakly by ABA, and group 3 comprises kinases strongly activated by ABA. So far, the ABA-dependent kinases belonging to group 3 have been studied most thoroughly. They are considered major regulators of plant response to ABA. The regulation of the plant response to ABA via SnRK2s pathways occurs by direct phosphorylation of various downstream targets, for example, SLAC1, KAT1, AtRbohF, and transcription factors required for the expression of numerous stress response genes. Members of group 2 share some cellular functions with group 3 kinases; however, their contribution to ABA-related responses is not clear. There are strong indications that they are positive regulators of plant responses to water deficit. Most probably they complement the ABA-dependent kinases in plant defense against environmental stress. So far, data concerning the physiological role of ABA-independent SnRK2s are very limited; it is to be expected they will be studied extensively in the nearest future.

The phytohormone abscisic acid (ABA) affects a wide range of stages of plant development as well as the plant's response to biotic and abiotic stresses. Manipulation of ABA signaling in commercial crops holds promising potential for improving crop yields. Several decades of research have been invested in attempts to identify the first components of the ABA signaling cascade. It was only in 2009, that two independent groups identified the PYR/PYL/RCAR protein family as the plant ABA receptor. This finding was followed by a surge of studies on ABA signal transduction, many of them using Arabidopsis as their model. The ABA signaling cascade was found to consist of a double-negative regulatory mechanism assembled from three protein families. These include the ABA receptors, the PP2C family of inhibitors, and the kinase family, SnRK2. It was found that ABA-bound PYR/RCARs inhibit PP2C activity, and that PP2Cs inactivate SnRK2s. Researchers today are examining how the elucidation of the ABA signaling cascade in Arabidopsis can be applied to improvements in commercial agriculture. In this article, we have attempted to review recent studies which address this issue. In it, we discuss various approaches useful in identifying the genetic and protein components involved. Finally, we suggest possible commercial applications of genetic manipulation of ABA signaling to improve crop yields.

“…Subsequent studies have demonstrated the functional conservation of the CBL-CIPK pathway in Populus (Yu et al, 2007), grape (Weinl and Kudla, 2009), sorghum (Li et al, 2010), and maize (Chen et al, 2011). Enhanced tolerance to diverse stresses has also been regularly observed in transgenic Arabidopsis because of the overexpression of CIPKs (Zhao et al, 2009;Chen et al, 2012), rice (Xiang et al, 2007), tomato Huertas et al, 2012), tobacco (Tripathi et al, 2009), and apple (Hu et al, 2012).…”

Molecular cloning and functional characterization of a novel CBL-interacting protein kinase NtCIPK2 in the halophyte Nitraria tangutorum

ABSTRACT. CBL-interacting protein kinases (CIPKs) mediate many plant responses to abiotic stress. However, their functions are poorly understood in halophytes. In this study, we isolated a CIPK gene, NtCIPK2, from the halophyte Nitraria tangutorum. By sequence alignment and the construction of a phylogenetic tree, we found that NtCIPK2 is similar to CIPK2 proteins from other plants, and contains conserved domains and motifs. The promoter of NtCIPK2 harbors many cis-acting elements that might be recognized and bound by transcription factors that are related to hormones and stress responses. NtCIPK2 was ubiquitously and robustly expressed in all tested organs, and was induced by salinity, drought, heat, and cold stress. The overexpression of NtCIPK2 in Escherichia coli caused better growth against high salinity, alkalinity, and osmotic conditions, dehydration, and extreme temperatures (i.e., heat and cold) compared to the control. 4717©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 13 (3): 4716-4728 (2014) Cloning and characterization of the NtCIPK2 gene Thus, NtCIPK2 is a candidate gene that might improve the stress tolerance of crops and herbs through genetic manipulation.
