ABI1 — Brassica oleracea

Summary

BoABI1 (BOLC102_C08P019400.1) on cabbage chromosome 8 encodes a protein with a PP2C domain and PPM-type phosphatase-like domain, annotated with abscisic acid binding, protein phosphatase regulator and inhibitor activities, and sucrose-phosphate synthase activity. The gene is associated with nectar secretion, actin filament-based processes, regulation of cytoskeleton organization, cell wall cellulose biosynthesis, and small GTPase-mediated signal transduction. It localises to the Arp2/3 protein complex, SCAR complex, SWI-SNF complex, and protein serine/threonine phosphatase complex. Associations include yield, seed viability, biomass yield, water use efficiency, stem diameter, petal length, root system morphology, and responses to flooding, water stress, and powdery mildew. Related genes in other species are linked to ABA-mediated stomatal closure, heat tolerance, cold stress tolerance, and lateral root development.
