Members of the ATP Binding Cassette B/Multidrug-resistance/P-glycoprotein (ABCB/MDR/PGP) subfamily were shown to function primarily in auxin transport. However, none of rice ABCB transporters have been functionally characterized. Here, we describe that a knock-down of OsABCB14 confers decreased auxin concentrations and polar auxin transport rates, conferring insensitivity to 2,4-D and IAA....
