The Conserved Ortholog Set (COS) of conifers' genes was identified via comparison of the Douglas-fir, loblolly pine, white spruce and sugi unigenes with COS sets identified in well-studied model plant species such as Arabidopsis, lettuce, and maize. To perform the BLAST searches, comparative analysis, and data visualization, we used the comparative genomics software PyMood™ (Allometra, Davis, California, USA). The resulting COS set of 52 genes has various uses for evolutionary genomics applications and can be efficiently utilized in phylogenetic analysis, comparative mapping, and to study synteny between different species.
