PIN1 — Brassica napus

Summary

BnPIN1 (DARMORV10_A07P39460.1) on chromosome A07 of oilseed rape encodes a member of the auxin efflux carrier family, possessing auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and binding capabilities for various phosphatidylinositol phosphates and clathrin. The gene is associated with auxin efflux, regulation of endocytosis, and cell polarization. It has been 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, plant height, and responses to gravity, blue light, phototropism, osmotic stress, ethylene, and brassinosteroids. Related genes in other species are associated with leaf venation patterning, phototropism, root meristem growth, flowering time, and salt tolerance.
