Changes in abundance of different modes of duplicated gene pairs over time. a The distribution of number of gene pairs derived from different modes of duplication in 141 plant genomes. Genomes with abnormal Ks peaks because fragmented assembly hindered the identification of large syntenic blocks were not included. b The fitted Ks peak corresponding to the most recent WGD for each species. cg The relationship between the log10-transformed number of different types of gene pairs and Ks peak of WGD genes from different taxa, excluding those taxa with abnormal Ks peaks due to fragmented assembly. c WGD-pairs. d TD-pairs: transposed gene pairs. e PD-pairs: proximal gene pairs. f TRD-pairs: transposed gene pairs. g DSD-pairs: dispersed gene pairs. Exponential fit and linear regression analysis were performed. The exponential equation was annotated in subplots c, f, and g; Pearson correlation coefficient (r) was annotated in subplots d and e
