Distribution of GS genes in the chromosomes of Populus trichocarpa. Linkage Groups (LG) numbers are indicated. PtGS1.3-827781 is located in the unassambled Scaffold 122. Arrows indicate the 5'-3' orientation of genes. Red arrows connected by horizontal solid lines are the duplicated GS genes. White arrows connected by dotted lines are duplicated collinear genes located adjacent to the positions where the GS genes are present. White arrows connected by dashed-dotted lines are internal duplicated genes. The position of genes is marked by the numbers of bp in each LG.
