Transcriptome Sequencing and Metabolism Analysis Reveals the role of Cyanidin Metabolism in Dark-red Onion (Allium cepa L.) Bulbs.

ABSTRACT: Onion (Allium cepa L.) is an important bulbous vegetable crop that possesses important properties related to health as well as extraordinary colors. Naturally white onion bulbs were used in this study to reveal the complex metabolic mechanisms that underlie phenotypic traits, especially bulb pigmentation. Six libraries (three dark-red and three white) were constructed and analyzed to elucidate differences in cyanidin (Cy) metabolism between dark-red and white onion bulbs. Libraries were screened using RNA-sequencing (RNA-seq) to reveal the differentially expressed genes (DEGs) involved in anthocyanin biosynthesis at the transcriptional level. Comparison with the Kyoto Encyclopedia of Genes and Genomes (KEGG) database shows that a total of 27 unigenes participate in onion anthocyanin biosyn
