AGR — Brassica oleracea var. botrytis

Summary

BoAGR (BOLND125_C03P015520.1_BOLND125_V1) on cauliflower chromosome 3 encodes an auxin efflux carrier of the PIN-like family, with annotated inositol-1,4-bisphosphate 1-phosphatase activity, phosphatidylinositol phosphate binding, and auxin efflux transmembrane transporter activity. The gene is associated with acropetal auxin transport, root gravitropic response, root hair initiation, and anthocyanin accumulation in response to UV light. It is linked to traits including gravity response, blue light sensitivity, relative root length, water use efficiency, stomatal resistance, leaf morphology, shoot branching, brassinosteroid content and sensitivity, ethylene sensitivity, osmotic response sensitivity, and stem senescence. The product localises to the basal plasma membrane, auxin efflux carrier complex, and PP2A complex. Studies of related genes in other species link the family to gravitropic response, auxin efflux, root growth direction, and salt tolerance.
