PP2A3 — triticum aestivum

Summary

TRAESCS6B02G213200 (symbol PP2A3, also known as TaPP2A-2) on bread wheat chromosome 6B encodes a serine/threonine-protein phosphatase with EC 3.1.3.16, belonging to the PPA2-like and calcineurin-like phosphoprotein phosphatase families. The gene is associated with protein serine/threonine phosphatase activity, metal binding, and localisation to the cytosol, cytoplasm, and nucleus. Annotated biological process associations include TOR signaling, stomatal closure, mitotic cell cycle, inhibition of RNAi, and response to thirst. The gene is associated with days to heading, days to flowering, days to maturity, drought tolerance, and wheat stripe rust disease response, as well as related phenotypes such as stripe rust severity and reaction type, heading date, flowering date, and Normalized Difference Vegetation Index. Studies of related genes in other species link the PP2A family to serine/threonine phosphatase function.
