PKS2 — Triticum aestivum

Summary

TRAESCS4D02G118500 (TaPKS2) on wheat chromosome 4D encodes a non-specific serine/threonine protein kinase with protein serine/threonine kinase activity and ATP binding, containing a NAF/FISL domain. This gene is associated with abscisic acid sensitivity and salinity stress tolerance, as observed for the SIP1 variant in wheat. It is linked to osmotic adjustment capacity, grain texture, stripe rust, germination rate, cold tolerance, protein content, seed germination, drought tolerance, grain hardness, head wax, and SDS sedimentation. The gene is associated with biological processes including hypersensitivity, transition metal transport, response to karrikin, calcium transport, proton transmembrane transport, response to nitrate, vacuole organization, protein membrane targeting, positive regulation of flavonoid anabolism, regulation of HR, intracellular signal transduction, osmotic response, cellular homeostasis, and responses to jasmonic acid and ethylene. Related genes in other species link the family to osmotic stress tolerance.
