Modulation in berry skin transcripts involved in the phenylpropanoid and flavonoid pathway in small and large berries at 47, 74, 103, and 121 DAA. Blue and red boxes indicate downregulated and upregulated transcripts, respectively, in small berries in relation to large berries. Boxes with bold margins indicate significant differences (adjusted P-value <0.05) between berry size treatments at a given developmental stage. Transcription factors (colored in yellow) involved in the regulation of the phenylpropanoid and/or the flavonoid pathway transcripts are depicted in dotted lines. PAL Phenylalanine lyase; C4H Cinnamate-4-hydroxylase; 4CL 4-Coumarate:coenzyme A ligase; CHI Chalcone isomerase; CHS Chalcone synthase; F3H Flavanone 3-hydroxylase; F3′H Flavonoid 3′-hydroxylase; F3′5′H Flavonoid 3′5′-hydroxylase; FLS flavonol synthase; DFR Dihydroflavonol 4-reductase; LAR Leucoanthocyanin reductase; LDOX Leucoanthocyanin dioxygenase; UFGT UDPglucose:flavonoid 3-O-glucosyltransferase; and AOMT Anthocyanin O-methyltransferase.
