Fig. 7: Regulation of the phenylpropanoid biosynthesis pathway in the russet fruit skin of sand pear.

a A partial diagram of phenylpropanoid biosynthesis constructed based on the KEGG pathway and gene expression data. Enzymes with enhanced expression in the russet fruit skin at the transcript and protein levels are shown in red. Transcript b and protein abundance c of russet-related genes involved in phenylpropanoid biosynthesis
