Figure 1

The evolution of the GmPHT1 gene family. A, Syntenic relationships among homologous blocks carrying the 15 GmPHT1 sequences after the Glycine WGD event. Similar colored blocks imply homology, the short red lines within these blocks show the location of GmPHT1s, and the black oval is the centromere. GmPHT1;15 is the pseudogene and the paralog gene of GmPHT1;11 was lost. B, The evolutionary model for GmPHT1-containing genomic blocks in the process of the soybean genome evolution, indicating GmPHT1s originated from four independent ancestors. Different backgrounds depict different whole genome duplication events. The colored blocks imply homology based on the average Ks values. The paralog gene of GmPHT1;11 was lost in the dotted block dotted, although other genes are collinear with the block containing GmPHT1;11. The detailed collinearity relationships are shown in Additional file 5C.
