RT   family in rice (Oryza sativa).";

CC   -!- FUNCTION: Aux/IAA proteins are short-lived transcriptional factors that
CC       function as repressors of early auxin response genes at low auxin
CC       concentrations. {ECO:0000250}.
CC   -!- SUBUNIT: Homodimers and heterodimers. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Highly expressed in flowers. Expressed in roots and
CC       etiolated seedlings. {ECO:0000269|PubMed:16200395}.
CC   -!- INDUCTION: Not induced by auxin. {ECO:0000269|PubMed:16200395}.
CC   -!- SIMILARITY: Belongs to the Aux/IAA family. {ECO:0000305}.
