CC   -!- FUNCTION: Involved in the dorsovental asymmetry of flowers. Promotes
CC       dorsal identity. {ECO:0000269|PubMed:15790677}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00624}.
CC   -!- TISSUE SPECIFICITY: Specifically expressed in the dorsal region of
CC       developing flowers. {ECO:0000269|PubMed:15790677}.
CC   -!- DEVELOPMENTAL STAGE: Early expressed at stage two (plastochrons 7 and
CC       8), when the floral meristem comprised a loaf-shaped bulge of cells.
CC       Expression was in the dorsal region of the floral meristem. At stage
CC       four, when sepal primordia had emerged around the meristem dome,
CC       expression could be seen in the dorsal sepal primordium. At stage five,
CC       expressed in emerging dorsal primordia of whorls two and three. In
CC       older flower buds (stages seven and eight), expression was found mainly
CC       in the dorsal petals and staminode. {ECO:0000269|PubMed:15790677}.
CC   -!- INDUCTION: Up-regulated by both CYC and DICH.
CC       {ECO:0000269|PubMed:15790677, ECO:0000269|PubMed:16236768}.
CC   -!- DISRUPTION PHENOTYPE: Radially symmetric flowers. Loss of functional
CC       stamens in dorsal positions. Organs reduction with five organs per
CC       whorl rather than six. {ECO:0000269|PubMed:15790677}.
