CRK — Sorghum bicolor

Summary

SbCRK (SORBI_3010G264400) on sorghum chromosome 10 encodes a protein with domains including CDPK_Ser/Thr_kinases, EF-hand-dom_pair, and Prot_kinase_dom, and is annotated with multiple molecular functions such as calcium-dependent protein serine/threonine kinase activity, glutamine synthetase activity, calmodulin binding, calcium ion binding, protein tyrosine kinase activity, DNA-binding transcription factor activity, and structural constituent of the cytoskeleton. The gene is associated with leaf senescence, heat acclimation, response to cytokinin, defence response to fungi, nitrate assimilation, microtubule-based processes, and intracellular signal transduction. It has been linked to traits including glutamine synthetase content, seed coat morphology, gibberellic acid sensitivity, cytokinin sensitivity, vegetative growth time, lateral root length, cell cycle, stress responses to high and low temperature, oxidative stress, root development, leaf senescence, and salinity tolerance. Studies of related genes in other species connect the family to calcium signaling, photosynthesis, salt and heat stress tolerance, root development, and seed coat development.
