Fig. 3: Identification of mQTLs on chromosomes 11, 14, and 18 for five features corresponding to different patterns of stilbenoid oligomerization.

a monomer–M229.1423T503, b monomer– M229.2006T789, c dimer– M453.1357T505, d trimer–M681.2169T759, and e tetramer–M907.2767T765. The GBS marker physical positions relative to the V. vinifera reference genome were used to extract genes associated with the mQTL peak. The green, purple, and gray boxes correspond to motifs associated with disease resistance, flavonoid biosynthesis, and terpenoid biosynthesis, respectively. The blue dotted line indicates genome-wide LOD significance thresholds (α = 0.10) calculated using 1000 permutations
