Transcriptional control of anthocyanin biosynthesis genes and transcription factors associated with flower coloration patterns in Gerbera hybrida.

ABSTRACT: We analyzed the expression of anthocyanin biosynthesis genes and transcription factors (TFs) in the Gerbera hybrida cultivars 'Bintang' and 'Alliance' that exhibit different coloration patterns. Differential expression of biosynthesis genes and TFs was associated with variable anthocyanin content at different flower developmental stages (S1-S3) in both cultivars; higher anthocyanin content was correlated with higher levels of gene expression. Exposure to different temperatures (6 and 22 °C) also resulted in different anthocyanin content levels: the lower temperature (6 °C) enhanced anthocyanin content compared to the higher temperature (22 °C). However, the increased anthocyanin content of 'Bintang' compared to 'Alliance' was the result of higher levels of expression of all detected genes,
