Expression -- Description ? help Back to Top
Source	Description
Uniprot	DEVELOPMENTAL STAGE: Expressed in mature flowers and decreases upon pollination. {ECO:0000269\|PubMed:15805488}.
Uniprot	TISSUE SPECIFICITY: Restricted to the petals, with the highest expression in the limb. {ECO:0000269\|PubMed:15805488}.

Functional Description ? help Back to Top
Source	Description
UniProt	R2R3 MYB-type transcription factor controlling the production of volatile benzoides in flowers by regulating the shikimate pathway, namely by activation of the 5-enol-pyruvylshikimate-3-phosphate synthase gene. This scent, mostly produced in the evening and night by the petals, attracts the pollinators. Anthocyanins production is not controlled by ODO1 as color and scent are produced at different stages of development. {ECO:0000269\|PubMed:15805488}.

Regulation -- Description ? help Back to Top
Source	Description
UniProt	INDUCTION: Increases before the onset of volatile emission at the end of the light period, peaks at night and decreases when volatile emission declines early morning.
