PIN1 — Brassica napus

Summary

BnPIN1, encoded by the gene DARMORV10_C02P31220.1 on chromosome C02 of oilseed rape (Brassica napus), is 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. This gene is associated with numerous developmental and physiological processes, including root regeneration, stigma development, anthocyanin accumulation in response to UV light, detection of oxidative stress, and regulation of endocytosis and cell polarization. It is linked to traits such as branch angle, seed set percent, lateral root number, leaf vein morphology, phototropism, and gravity response. Studies of related genes in other species connect the family to polar auxin transport, leaf venation patterning, phototropism, root meristem growth, and flowering time.
