We analyzed the evolutionary pattern of the granule-bound starch-synthase genes (GBSS) in 20 land plants and 2 algae from whole-genome data with bioinformatics methods. A total of 42 genes were detected and their sequence structures were characterized. Phylogenetic analysis revealed that the GBSS gene family had an ancient origin and complex evolutionary history. It probably appeared in the early evolutionary stage of green plants, then mostly experienced lineage-specific expansion and copy loss during evolution, and finally was fixed in different plant taxa via functional divergence.
