Fig. 3From: Generation of expressed sequence tags for discovery of genes responsible for floral traits of Chrysanthemum morifolium by next-generation sequencing technologyClassification of DXS genes. a Phylogenetic tree of DXS genes of Arabidopsis and chrysanthemum. According to our definition, same-colored contigs are classified into the same cluster. b–d Amino-acid alignment of the contigs in each cluster. Contigs in the same cluster share very high sequence homologyBack to article page
