Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	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. Ref.1
Subcellular location	Nucleus Probable.
Tissue specificity	Restricted to the petals, with the highest expression in the limb. Ref.1
Developmental stage	Expressed in mature flowers and decreases upon pollination. Ref.1
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.
Sequence similarities	Contains 2 HTH myb-type DNA-binding domains.
