Figure 7From: Comparative genomics reveals conservative evolution of the xylem transcriptome in vascular plantsPhylogenetic trees for ancestral xylem orthologs in land plants. Deduced amino acid or protein sequences of 501 ancestral xylem orthologs from 7 species were combined to build consensus trees using three alignment methods, including Kalign (A), ClustalX2 and Mafft (B) with a bootstrap of 1,000. Individual trees were also generated for each gene using CLC Genomic Workbench 3 (CLC bio, Denmark). Genes with phylogenetic trees paralleled the trend of plant evolution (235, 47%) were present in an example (C) while genes that diverged from plant evolution (266, 53%) had diverse patterns of molecular evolution. A representative phylogenetic tree of genes (158, 32%) with conserved branches between angiosperms and ancient plant species but divergent branches to gymnosperms is showed in example (D).Back to article page
