OSK1 (TRAESCS1D02G353300) — triticum aestivum

Summary

TRAESCS1D02G353300 (OSK1, also known as TaSnRK1.1) encodes a non-specific serine/threonine protein kinase with protein serine/threonine kinase activity (EC 2.7.11.1), ATP binding, and kinase binding functions. It contains a protein kinase domain, UBA domain, and KA1 domain, and localizes to the cytoplasm and nucleus. In bread wheat, OSK1 is associated with grain development, alpha-amylase gene expression, and responses to carbohydrate, abscisic acid signaling, and intracellular signal transduction. It is also linked to floral meristem maintenance, floral organ identity specification, and flower development. The gene has been connected to agronomically important traits including grain quality, alpha-amylase activity, canopy temperature, sucrose content, drought tolerance, days to heading, days to flowering, days to maturity, and wheat stripe rust disease response. Studies of related genes in other species link the family to sugar signaling pathways.
