AGR — Nicotiana attenuata

Summary

A4A49_00744 (AGR, also known as PIN1) on chromosome 10 of coyote tobacco (Nicotiana attenuata) encodes a member of the auxin efflux carrier family, possessing auxin efflux transmembrane transporter activity, inositol-1,4-bisphosphate 1-phosphatase activity, and phosphatidylinositol phosphate binding. This gene is associated with auxin efflux transport, auxin signalling, root gravitropism, regulation of seed size, and reproductive structure development. It is linked to numerous traits including gravity response, phototropism, blue light sensitivity, shoot growth angle, leaf vein morphology, seed set percent, stamen morphology, adventitious root formation, lateral root number, root hair length, and auxin content. The encoded protein localizes to the auxin efflux carrier complex, basal plasma membrane, recycling endosome, and clathrin-coated endocytic vesicle, and is associated with tropism, regulation of endocytosis, anthocyanin accumulation in response to UV light, and cellular response to basic pH.
