SAPK1 — Triticum aestivum

Summary

TRAESCS2B02G521800, also known as TaPKABA1 or SAPK1 on wheat chromosome 2B, encodes a serine/threonine protein kinase (EC 2.7.11.1) with ATP binding activity, belonging to the SNF1-type protein kinase family. The gene is associated with abscisic acid (ABA) signaling, protein phosphorylation, signal transduction, embryogenesis, seedling development, and carbohydrate metabolism. Its product localizes to the cytosol, cytoplasm, and nucleus. TaPKABA1 is associated with salinity and drought tolerance, sprouting tolerance, seed dormancy and maturation, grain yield, grain weight and size, grain protein content, plant height, spike length, panicle length, root thickness, anthesis time, and seed coat color. Related genes in other species are linked to abiotic stress tolerance and root growth, and to black point incidence and heat tolerance.
