PKABA1 (TRAESCS4B02G079300) — triticum aestivum

Summary

TRAESCS4B02G079300, designated TaPKABA1 (also known as TaSnRK2.3 or SAPK10), encodes a non-specific serine/threonine protein kinase (EC 2.7.11.1) with protein serine/threonine kinase activity and ATP binding. This bread wheat gene on chromosome 4B is associated with ABA signaling, embryogenesis, seedling development, cellular homeostasis, protein phosphorylation, lipid metabolism, transport, cell communication, cell death, and defence response to bacteria. It localizes to the cytosol, cytoplasm, and nucleus. TaPKABA1 is associated with grain yield, grain weight, spike length, plant height, panicle length, seed maturation, seed dormancy, drought tolerance, and salt tolerance. Related genes in other species are linked to abscisic acid-inducible protein kinase activity.
