ABI1 (BOLND125_C07P057550.1_BOLND125_V1) — Brassica oleracea var. botrytis

Summary

BoABI1 (BOLND125_C07P057550.1) on cauliflower chromosome 7 encodes a protein with PP2C and PPM-type phosphatase domains and is annotated with abscisic acid binding, protein phosphatase regulator and inhibitor activities, and sucrose-phosphate synthase activity. The gene is associated with numerous biological processes including nectar secretion, regulation of actin polymerization, cell wall cellulose biosynthesis, seed germination, and responses to flooding and glucose signalling. It localises to the Arp2/3 protein complex, SCAR complex, and SWI-SNF complex. BoABI1 is linked to agronomically important traits such as yield, seed yield, biomass, water use efficiency, stem diameter, inflorescence size, leaf elongation rate, root system morphology, and responses to water stress, nitrogen, and powdery mildew. Related genes in other species are linked to ABA-mediated stomatal closure, drought recovery, heat and cold stress tolerance, and sucrose biosynthesis.
