May be a general defense protein (By similarity). Seems involved in turion (dormant buds) formation. Confers resistance to the diterpenoid antifungal agent sclareol. Ubiquitous. Induced by abiotic stresses such as cold-stress, cycloheximide and sodium chloride (NaCl). Induction by abscisic acid (ABA) is repressed by cytokinin such as kinetin (at protein level). Belongs to the ABC transporter superfamily. ABCG family. PDR (TC 3.A.1.205) subfamily.
