Summary

Go to the top of the page Help

Gene symbol: IBR1
Gene description: indole-3-butyric acid response 1
Primary source: Araport:AT4G05530
Locus tag: AT4G05530
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
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.
