ABI1 — Triticum aestivum

Summary

TRAESCS1B02G475700 (TaABI1) on wheat chromosome 1B encodes a protein with PP2C and PPM-type phosphatase domains, annotated with sucrose-phosphate synthase activity, kinase regulator activity, and protein phosphatase regulator activity. This gene is associated with pre-harvest sprouting, regulation of actin polymerization, small GTPase-mediated signal transduction, and glucose-mediated signaling. It is linked to traits including seed yield, biomass yield, leaf elongation rate, root system morphology, water stress response, wheat powdery mildew disease response, and responses to aluminum, nitrogen, and potassium. Localization evidence links the product to the Arp2/3 protein complex, SCAR complex, SWI-SNF complex, and secondary cell wall. Related genes in other species are linked to drought resistance, root architecture, root hair elongation, ABA-regulated gene expression, heat stress tolerance, and arsenate tolerance.
