The ‘Evolution’ module consists of phylogenetic, sequence identity and Ka/Ks analysis tools. The phylogenetic tool provides the phylogenetic relationship of candidate flowering genes between multiple species. Furthermore, we provide the phylogenetic analysis function for the gene family in phylogenetic module. The shared homologous genes can be accessed according to the positions of candidate flowering genes in the phylogenetic tree.
In the sequence identity  tool, users can view the detailed information of every individual candidate flowering gene and perform gene collinearity analysis using a multiple sequence alignment viewer. Sequence logos are provided across the top of the graphic, wherein the height of the letter corresponds to the amount of conservation of the corresponding amino acid.
The Ka/Ks ratio was used to diagnose the form of sequence evolution. The Ka/Ks  module provides the comparison of Ka/Ks of candidate flowering genes between 112 species. We also provides multiple dynamic charts for users to visualize and investigate the Ka/Ks distribution.
