Phylogeny and evolutionary history of glycogen synthase kinase 3/SHAGGY-like kinase genes in land plants.

ABSTRACT:

Background

GSK3 (glycogen synthase kinase 3) genes encode signal transduction proteins with roles in a variety of biological processes in eukaryotes. In contrast to the low copy numbers observed in animals, GSK3 genes have expanded into a multi-gene family in land plants (embryophytes), and have also evolved functions in diverse plant specific processes, including floral development in angiosperms. However, despite previous efforts, the phylogeny of land plant GSK3 genes is currently unclear. Here, we analyze genes from a representative sample of phylogenetically pivotal taxa, including basal angiosperms, gymnosperms, and monilophytes, to reconstruct the evolutionary history and functional diversification of the GSK3 gene family in land plants.
