PIN1 — Brassica napus

Summary

BnPIN1 (DARMORV10_A02P18810.1) on chromosome A02 of oilseed rape encodes a member of the auxin efflux carrier family, possessing auxin efflux transmembrane transporter activity and also annotated with inositol-1,4-bisphosphate 1-phosphatase activity, phosphatidylinositol phosphate binding, and clathrin binding. The gene is associated with auxin efflux and endocytic recycling, and localizes to the auxin efflux carrier complex, recycling endosome, and basal plasma membrane. It is linked to numerous agronomic traits including branch angle, shoot growth angle, lateral root number and length, root mass density, leaf number and shape, petiole length, stamen length, seed set percent, and plant height. Additional associations include responses to oxidative stress, boron, and cation stress, as well as regulation of cell polarization, phragmoplast microtubule organization, and anthocyanin accumulation in response to UV light. Studies of related genes in other species link the family to leaf venation pattern, phototropism, root meristem growth, and flowering time.
