ABI1 (TRAESCS3B02G240000) — triticum aestivum

Summary

TRAESCS3B02G240000 (TaABI1) on bread wheat chromosome 3B encodes a protein with a PP2C phosphatase domain and is annotated with diverse molecular functions including sucrose-phosphate synthase activity, kinase regulator activity, and protein phosphatase binding. This gene is associated with numerous biological processes such as regulation of actin polymerization, small GTPase-mediated signal transduction, and pre-harvest sprouting. TaABI1 is linked to traits including seed yield, biomass yield, leaf elongation rate, wheat powdery mildew disease response, water stress response, and aluminum response. It has been connected to phenotypes involving stomatal movement, dehydration tolerance, photosynthetic efficiency, carbohydrate metabolism, and sucrose synthesis. Related genes in other species link the family to drought resistance, root architecture, ABA responses, heat tolerance, glucose tolerance, and abscisic acid binding.
