Species Oryza sativa (Rice) [ GR_tax:013681 ]
Accession GR:0020024
Gene Symbol iaa20
Gene Name indoleacetic acid 20 
Synonyms (7)
E.C. Numbers (0)
Pathway Reactions (0)
Chromosome No. 6
Gene Type CDS (Protein coding)
Has Phenotype no
Description Early auxin responsive gene. Aux/IAA genes encode short-lived transcriptional factors that act to repress the expression of early auxin response genes when auxin concentrations are low.
Curator Comment Relative mRNA levels of iaa20 are highest in the Callus; they are lowly expressed in other tissues. There is a massive increase in mRNA expression levels when coleoptile segments of 3-day-old etiolated seedlings are treated with 30 micro mols of 2,4-D in comparison to auxin depleted controls. iaa20 is a sister gene to iaa9 and shares similar expression profiles.
