Expression -- Description ? help Back to Top
Source Description
UniprotDEVELOPMENTAL STAGE: Early expressed at stage two (plastochrons 7 and 8), when the floral meristem comprised a loaf-shaped bulge of cells. Expression was in the dorsal region of the floral meristem. At stage four, when sepal primordia had emerged around the meristem dome, expression could be seen in the dorsal sepal primordium. At stage five, expressed in emerging dorsal primordia of whorls two and three. In older flower buds (stages seven and eight), expression was found mainly in the dorsal petals and staminode. {ECO:0000269|PubMed:15790677}.
UniprotTISSUE SPECIFICITY: Specifically expressed in the dorsal region of developing flowers. {ECO:0000269|PubMed:15790677}.

  2. There was strong genotype-dependent suppression of tomato morphogenesis-regulating transcription factor SANT/HTH-Myb (SlMyb) due to viroid pathogenesis.
