    Also known as
    INCREASED BOTRYTIS RESISTANCE 1; indole-3-butyric acid response 1; SDRA; SHORT-CHAIN DEHYDROGENASE/REDUCTASE A; T1J24.9; T1J24_9
    Summary
    Encodes a peroxisomal member of the short-chain dehydrogenase/reductase (SDR) family of enzymes. Loss of IBR1 function causes increased resistance to indole-3-butyric acid without affecting plant responses to IAA, NAA, and 2,4-D. This enzyme may be responsible for catalyzing a dehydrogenation step in the beta-oxidation-like conversion of IBA to IAA.
