Fig. 6From: New quantitative trait locus (QTLs) and candidate genes associated with the grape berry color trait identified based on a high-density genetic mapThe expression patterns of all genes and candidate genes in the QTL regions. M1, M2, M3, and M4 and R1, R2, R3, and R4 refer to the four berry development stages of ‘Muscat Hamburg’ and ‘Red Globe’, respectively. The block colored from blue to red indicates a gradual increase in gene expression levelBack to article page
