Synteny block 1. A syntenic block of soybean, M. truncatula and A. thaliana genes surrounding soybean's rhg1 gene (Gm gene 21). Solid black lines connect homologs. Dotted black lines indicate that the absence of a homolog in the syntenic position. Blue lines connect orthologs. Pink lines connect paralogs. M. truncatula genes are shown in red, soybean in brown, and A. thaliana in blue. Lighter colored genes represent those that had no significant similarity to Genbank's nonredundant protein database. Gray genes are repetitive elements. A thick gray vertical line connecting sequence assemblies indicate regions in which sequence is not yet available but in which linkage and approximate distance were determined. Genbank accessions are shown in gray.
