Genomic synteny of several SEO genes from M. truncatula and G. max. Schematic overview of the genomic synteny of SEO clusters on M. truncatula chromosome 1 and G. max chromosomes 2, 10, 13 and 20. SEO genes are shown as red arrows. Other gene models are shown as black arrows. Orthologs between the two Fabaceae and paralogs within G. max are connected by dark grey shading. Orthologs and paralogs for non-SEO genes are indicated by light grey shading.
