Fig. 2From: Comparative genomics and transcriptomics analysis reveals evolution patterns of selection in the Salix phylogenyFunctional annotation and divergence between orthologues of 9 Salix and one Populus species. The heat map is based on the 238 putatively orthologous transcripts of 10 species (Named orth1-orth238). The orthologues were annotated to different function with Gene Ontology (GO) (Additional file 1: Table S3). The sequences of 238 orthologues are shown in Additional file 3Back to article page
