comment
  • FUNCTION Acts as a component of the auxin efflux carrier. Involved in the polar auxin transport which may regulate crown root development and response to water stress.SUBUNIT Homodimer.SUBCELLULAR LOCATION Expressed in coleoptiles, roots, vascular bundles of leaves, shoots, lamina joints and vascular bundles of the lemma and filament (PubMed:22882529). Expressed in stem bases, stems, leaves and young panicles (PubMed:19825657).INDUCTION By auxin and osmotic stress. Down-regulated by 1-N-naphthylphthalamic acid (NPA), an auxin efflux inhibitor.MISCELLANEOUS Seedlings silencing PIN3A display abnormal crown root development. Seedling over-expressing PIN3A exhibit better shoot growth, longer roots and a greater number of adventitious roots than the wild-type when grown on PEG-induced osmotic stress.SIMILARITY Belongs to the auxin efflux carrier (TC 2.A.69.1) family.
