Research Abstract
The mechanism of picotee formation with environmental factors was investigated in Camellia japonica 'Tamanoura' flowers. As a result of analysis of the expression level of the transcription factor, no significant difference was observed between the white and red regions in the petals, suggesting that it may be due to post-transcriptional gene silencing. The petals collected before and after petal coloration were subjected to temperature and chemical treatments, but the picotee formation could not be controlled. Infection of cucumber mosaic virus to camellia 'Tamanoura' plants did not affect the picotee formation, so that it was suggested that picotee formation was resulted from post-transcriptional gene silencing.
