PEPKR2 — Triticum aestivum

Summary

TRAESCS5A02G246700 (symbol TaPEPKR2) on bread wheat chromosome 5A encodes a calcium-dependent protein serine/threonine kinase with calmodulin-binding and calcium-ion-binding domains, placing it in the CDPK/Ser/Thr kinase family. The gene is associated with intracellular signal transduction and localises to the membrane, cytoplasm and nucleus. It has been linked to salicylic acid signalling and hormone-signalling pathways, and to the NAC54, GRAS2 and DREB2B genes. TaPEPKR2 is associated with agronomically important traits including grain yield, plant height, drought tolerance and high-temperature stress response. Studies of related genes in other species link the family to heat and dehydration tolerance.
