Analysis of Key Genes Involved in Potato Anthocyanin Biosynthesis Based on Genomics and Transcriptomics Data.

ABSTRACT: The accumulation of secondary metabolites, such as anthocyanins, in cells plays an important role in colored plants. The synthesis and accumulation of anthocyanins are regulated by multiple genes, of which the R2R3-MYB transcription factor gene family plays an important role. Based on the genomic data in the Potato Genome Sequencing Consortium database (PGSC) and the transcriptome data in the SRA, this study used potato as a model plant to comprehensively analyze the plant anthocyanin accumulation process. The results indicated that the most critical step in the synthesis of potato anthocyanins was the formation of p-coumaroyl-CoA to enter the flavonoid biosynthetic pathway. The up-regulated expression of the CHS gene and the down-regulated expression of HCT significan
