SNRK1 — triticum aestivum

Summary

TRAESCS6D02G141000 (TaSNRK1, also known as TaCIPK21) on wheat chromosome 6D encodes a protein serine/threonine kinase with a NAF/FISL domain, calcium ion binding, ATP binding, and kinase activity. This gene is associated with diverse biological processes including cellular osmotic and salinity responses, potassium ion homeostasis, calcium signaling, autophagy, sucrose and carbohydrate metabolism, glutathione anabolism, and telomere maintenance. It is linked to agronomically important traits such as grain weight, grain yield, seed dormancy, seed germination, stripe rust resistance, drought tolerance, heat tolerance, cold tolerance, stomatal opening and closure, transpiration rate, net photosynthetic rate, quantum yield, and canopy temperature. The encoded protein localizes to the tonoplast, vacuole, plastid, membrane, cytosol, and nucleus. Studies of related genes in other species connect the family to telomere length regulation, magnesium tolerance, and floral pattern formation.
