Anthocyanins and Anthocyanin Biosynthesis Gene Expression in <i>Passiflora</i> Flower Corona Filaments.

ABSTRACT: The diversity in anthocyanin flower pigmentation is vital in the ornamental plant market. To understand the regulation of the corona filament pigmentation of the Passiflora flower, we investigated the anthocyanin profiles of five distinct species (P. violacea, P. caerulea, P. edulis, P. incarnata, and P. coccinea) using HPLC-MS. A total of 14 anthocyanins, differentially distributed in the analyzed species, were identified as responsible for the differences in corona color, which can be attributed to different ratios of pelargonidin, cyanidin, and delphinidin. Additionally, we evaluated the expression of some biosynthetic genes, including dehydroflavonol reductase (DFR), flavonoid 3'-hydroxylase (F3'H), and flavonoid 3',5'-hydroxyl
