TL;DR
This study explores the molecular basis of flower color variation in cherry blossoms using metabolomics and transcriptomics.
Contribution
The study identifies key genes and metabolites linked to anthocyanin pathways in hybrid cherry blossoms.
Findings
84 flavonoid metabolites were identified, with 31 linked to the anthocyanin pathway.
Nine key enzyme genes correlated with anthocyanin accumulation were identified through joint analysis.
Differential gene expression patterns were observed between parent and hybrid cherry blossom varieties.
Abstract
Flower color, as an important trait of ornamental plants, has been a research hotspot in recent years. In this study, we selected Prunus campanulata (Maxim.) (ZH, red), P. dielsiana (Schneid.) (WH, white), and two cherry blossom varieties ‘Yanzhi Fei’ (FH, deep pink) and ‘Yanzhi Xue’ (XH, pinkish white) obtained by open-pollination hybridization as material. By means of bioinformatics methods such as metabolomics and transcriptomics, it is expected to deeply study the molecular mechanism of the gradient changes in flower color between the parents and offspring of cherry blossoms. Metabolomics analysis indicated that a total of 84 flavonoid related metabolites were identified, among which 31 were associated with the anthocyanin metabolic pathway, including three major types of anthocyanin substances: cyanidin, delphinidin, and malvidin. Transcriptome analysis showed that a total of 7712…
