PIN1 — Brassica napus

Summary

BnPIN1, encoded by the gene DARMORV10_C06P47680.1 on chromosome C06 of oilseed rape (Brassica napus), is a member of the auxin efflux carrier family, possessing auxin efflux transmembrane transporter activity and inositol-1,4-bisphosphate 1-phosphatase activity. It is associated with auxin efflux, regulation of endocytosis, and regulation of cell polarization. The gene is linked to numerous agronomic traits, including branch angle, shoot growth angle, lateral root number and length, root mass density, seed set percent, leaf vein morphology, plant height, and stamen and anther morphology. It is also associated with detection of oxidative stress, response to boron, response to cation stress, and anthocyanin accumulation in tissues in response to UV light. Studies of related genes in other species link the family to leaf vascular patterning, phototropism, root meristem growth, and flowering time.
