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.
