How the Color Fades From Malus halliana Flowers: Transcriptome Sequencing and DNA Methylation Analysis.

ABSTRACT: The flower color of many horticultural plants fades from red to white during the development stages, affecting ornamental value. We selected Malus halliana, a popular ornamental species, and analyzed the mechanisms of flower color fading using RNA sequencing. Forty-seven genes related to anthocyanin biosynthesis and two genes related to anthocyanin transport were identified; the expression of most of these genes declined dramatically with flower color fading, consistent with the change in the anthocyanin content. A number of transcription factors that might participate in anthocyanin biosynthesis were selected and analyzed. A phylogenetic tree was used to identify the key transcription factor. Using this approach, we identified MhMYB10 as directly regulating anthocyanin biosy
