Integrated Metabolomic and Transcriptomic Analyses Reveal Novel Insights of Anthocyanin Biosynthesis on Color Formation in Cassava Tuberous Roots.

ABSTRACT: Yellow roots are of higher nutritional quality and better appearance than white roots in cassava, a crucial tropical and subtropical root crop. In this work, two varieties with yellow and white cassava roots were selected to explore the mechanisms of color formation by using comparative metabolome and transcriptome analyses during seven developmental stages. Compared with the white-rooted cassava, anthocyanins, catechin derivatives, coumarin derivatives, and phenolic acids accumulated at higher levels in yellow-rooted cassava. Anthocyanins were particularly enriched and displayed different accumulation patterns during tuberous root development. This was confirmed by metabolic comparisons between five yellow-rooted and five white-rooted cassava accessions. The integrative metabolomic and tr
