SNRK1 — triticum aestivum

Summary

TRAESCS6A02G151000 (TaSNRK1, also known as TaCIPK21-6A) on wheat chromosome 6A encodes a protein serine/threonine kinase with a NAF/FISL domain, calcium ion binding, ATP binding, and telomeric single-stranded DNA binding activities. The gene is associated with diverse biological processes including calcium signaling, autophagy, cellular osmotic and salinity responses, potassium ion homeostasis, sucrose and carbohydrate metabolism, chloroplast organization, and positive regulation of telomere maintenance. It is linked to agronomically important traits such as grain weight, grain size, grain yield, drought tolerance, heat tolerance, cold tolerance, photosynthetic rate, stomatal opening and closure, canopy temperature, starch and sucrose content, root hair length, and floral organ development. The encoded protein localizes to multiple cellular compartments including the tonoplast, vacuole, plastid, plasma membrane, cytosol, and nucleus.
