SNRK1 — Triticum aestivum

Summary

TRAESCS6B02G179100 (TaSNRK1, also known as TaCIPK21-6B) on wheat chromosome 6B encodes a protein serine/threonine kinase with a NAF/FISL domain, calcium ion binding, ATP binding, and telomeric ssDNA binding activities. It 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. The gene has been linked to agronomically important traits such as grain weight, grain size, seed dormancy, seed germination, stripe rust, drought tolerance, heat tolerance, cold tolerance, canopy temperature, net photosynthetic rate, quantum yield, stomatal opening and closure, transpiration rate, root hair length, floral organ development, and magnesium sensitivity. The protein localizes to the tonoplast, vacuole, plastid, plasma membrane, cytosol, and nucleus.
