A list of the 11 key sugar metabolism genes

A total of 11 key genes were identified for further targeted validation analyses due to their significant correlation with sugar contents as identified through Pearson correlation coefficient (PCC) analysis (Table 2) and to their high number of edges within their respective modules, suggesting that they could behave as putative hub genes, as revealed by weighted gene co-expression network analysis (Supplementary Table S2)
