Transcriptome and Metabolome Analyses Reveal the Mechanism of Color Differences in Pomegranate (<i>Punica granatum</i> L.) Red and White Petals.

ABSTRACT: Pomegranate (Punica granatum L.) is an important economic tree, possessing both edible and ornamental value. Flower color is an important ornamental trait of pomegranate, but the color formation pattern and related molecular mechanisms of pomegranate petals are still unclear. In this study, we conducted physiological, transcriptomic, and metabolomic studies on the petals of Tunisia and White pomegranate varieties during the blooming stage. The results showed that compared to White petals, the contents of anthocyanin, carotenoid, and sucrose in Tunisia petals were significantly increased, while the flavonoid content was significantly decreased. Through RNA-seq, 23 DEGs were identified in the anthocyanin synthesis, and 3 DEGs were identified in the carotenoid synthesis. Transcription
