AGR — Nicotiana attenuata

Summary

A4A49_10554, designated AGR and also known as PIN6 in coyote tobacco (Nicotiana attenuata) on chromosome scaffold00153, encodes a protein with auxin efflux carrier and auxin influx transmembrane transporter activities, as well as inositol-1,4-bisphosphate 1-phosphatase activity and phosphatidylinositol phosphate binding. This gene is associated with auxin efflux carrier complexes and localizes to the basal plasma membrane, recycling endosomes, and clathrin-coated vesicles. It is linked to tropism, detection of oxidative stress, regulation of endocytosis, cell wall organization, and anthocyanin accumulation in response to UV light. Associations include traits such as root length, shoot branching, leaf vein morphology, seed set, auxin content, and responses to blue light, osmotic stress, and herbicides. Studies of related genes in other species connect the family to root patterning, fruit development, and insect resistance.
