Comparative genomics and transcriptomics analysis reveals evolution patterns of selection in the Salix phylogeny.

Background: Willows are widely distributed in the northern hemisphere and have good adaptability to different living environment. The increasing of genome and transcriptome data provides a chance for comparative analysis to study the evolution patterns with the different origin and geographical distributions in the Salix phylogeny.

Results: Transcript sequences of 10 Salicaceae species were downloaded from public databases.
