Integrative analysis of the transcriptome and metabolome reveals the peel coloration mechanism of Zanthoxylum armatum.

ABSTRACT:

Background

Zanthoxylum armatum is a globally recognized medicinal and edible plant, the fruit peel color of which is considered an important trait that influences its economic value. In this study, Z. armatum fruits were used at five different stages of development to explore the law of metabolite biosynthesis and its potential molecular mechanism.

Results

Using transcriptomic and widely-targeted metabolomic analyses, 23 differentially accumulated metabolites, 274 differentially expressed structural genes, and 230 differentially expressed transcription factor genes associated with anthocyanin synthesis were identified. Based on co-expression network analysis, key structural genes positively associated with anthocyanin biosynthesis were identified and the corresponding hub tr
