In parentheses, the subfamilies to which the genes belong according to Ref. 11 (RBR genes) and this study (HECT genes). The table details the correlation coefficients for each pair of genes. In bold, significant comparisons (all of them with p<0.005 after Bonferroni’s correction, except the comparison AT4g19670/UPL2, which has p = 0.027).
