CRK (TRAESCS2D02G173100) — triticum aestivum

Summary

TRAESCS2D02G173100, designated TaCRK on wheat chromosome 2D, encodes a protein kinase domain-containing protein with CDPK_Ser/Thr_kinases, EF-hand-dom_pair, and calmodulin-binding activity, and is also annotated for glutamine synthetase activity, DNA binding, and structural cytoskeletal roles. The gene is associated with regulation of amino acid metabolism, nitrate assimilation, microtubule-based processes, and ethylene and gibberellic acid signaling. TaCRK has been linked to traits including seed coat morphology, lateral root length, vegetative growth time, and responses to high and low temperature, oxidative stress, and cold. It is also associated with heat stress-induced male sterility, seed size, nitrogen assimilation, ROS homeostasis, and salt and cold stress tolerance. Studies of related genes in other species link the CRK family to calcium signaling, photosynthesis, root development, seed coat development, and heat and salt stress tolerance.
