Boxplot of expression comparison between genes within repositioned centromeres in P. alba var. pyramidalis and genes within homologous regions in S. chaenomeloides, and vice versa. Asterisks represent significant differences (two-tailed Wilcoxon rank-sum test, **** P ≤ 0.0001, *** P ≤ 0.001, ** P ≤ 0.01, * P ≤ 0.05, ns: not significant).
