Chromosome location and collinearity of soybean PK genes. (A) Chromosomal locations of soybean PKs. The coloured boxes denote different groups of the soybean PK family. (B) Collinearity events among all duplicated PKs in the soybean genome. The bars denote collinearity events contributed by 13-Mya whole-genome-wide duplication (WGD) (K s values 0.06–0.39) and by 59-Mya WGD (K s values 0.40–0.80) and by other WGD events. (C, D) The collinearity events contributed by the 13-Mya (C) and 59-Mya whole-genome-wide duplication (WGD) events (D). (E) Contribution of the 13 and 59 Mya duplication events to the expansion of soybean PKs. The K s values (synonymous distance) of collinearity events (1357) for all syntenically duplicated PKs (1547 genes) were calculated the MCScanX program. The K s values of 0.06–0.39 were used to differentiate the events contributed by the 13-Mya WGD from those contributed by the 59-Mya WGD events (K s values 0.40– 0.80).
