Combined Analysis of Transcriptome and Metabolome Explains the Differences in Pulp Color in Jackfruit

Plant Direct, Volume 10, Issue 2, February 2026.
ABSTRACT The pulp color of jackfruit reflects variations in its nutritional composition and influences market preference. We investigated the mechanism underlying pulp coloration through an integrated transcriptomic and metabolomic analysis of three jackfruit cultivars—light yellow “THA”, yellow “GTM”, and orange “YNH”.
