ABC transporter controlling the release of volatile organic compounds (VOCs), including floral volatile benzenoids and phenylpropanoids (FVBP), in flowers of fragrant cultivars (e.g. cv. Mitchell and cv. V26) (PubMed:22345641, PubMed:28663500). This scent, mostly produced in the evening and night by the petals, attracts the pollinators (e.g. the night-active hawkmoth pollinator Manduca sexta) (PubMed:22345641). Homodimer. Restricted to the petals, with the highest expression in the limb and, to a lesser extent, in petal tubes, probably in both epidermal and mesophyll cell layers. Accumulates during flower development with highest levels in open flowers, and fades out as flowers are senescing. In fragrant cultivars (e.g. cv. Mitchell and cv. V26), 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; this precise regulation is tuned by ODO1 binding and activation of its promoter. Disturbed release of volatile organic compounds (VOCs) in flowers, including benzoides and phenylpropanoids, which accumulate to toxic levels in the plasma membrane. Belongs to the ABC transporter superfamily. ABCG family.
