Evolution of gene conversion. a Gene conversion in species divergence events. The numbers on different coloured lines indicate the number of gene conversions in different species at different times. b The rates of WCV and PCV in the three genomes. In the histogram, orange represents the number of all gene conversions, blue represents the number of PCVs, and red represents the number of WCVs. c Evolutionary trees of genes in which gene conversion occurred. The gene Oj12g0106200.01 was wholly converted by its paralogous gene Oj11g0106900.01 in GJ. d Multiple sequence alignment of one selected quartet. The blue highlighted areas indicate 100% similarity, and the red highlighted areas indicate 75% similarity. The 19–36 bp nucleotide sites of Zs11g2288.01 and Zs12g1247.01 underwent gene conversion, and the donor was Zs12g1247.01. The sequence in the red rectangle indicates partial gene conversion
