ABI1 (TRAESCS3A02G209200) — triticum aestivum

Summary

TRAESCS3A02G209200 (TaABI1) on wheat chromosome 3A encodes a protein with protein phosphatase regulator activity, kinase regulator activity, and sucrose-phosphate synthase activity, and belongs to the PP2C family. It is associated with pre-harvest sprouting, water stress response, osmotic response sensitivity, and wheat powdery mildew disease response. The gene is linked to seed yield, biomass yield, seed viability, leaf elongation rate, root system morphology, and plant cell shape. It is associated with stomatal movement, dehydration tolerance, photosynthetic efficiency, hypoxia tolerance, and carbohydrate metabolism. Localisation evidence places the product at the cell periphery, secondary cell wall, and protein serine/threonine phosphatase complex. Studies of related genes in other species link the family to drought resistance, root architecture, and ABA responses, and to heat tolerance, glucose tolerance, and abscisic acid binding.
