Figure 1From: Partial functional conservation of IRX10 homologs in physcomitrella patens and Arabidopsis thalianaindicates an evolutionary step contributing to vascular formation in land plantsSequence alignment of the Arabidopsis , Populus and Physcomitrella IRX10 protein family. IRX10 related protein sequences from Arabidopsis, Populus and Physcomitrella were aligned using Clustal-X. Shading indicates 100% conservation (black), 80% conservation (dark grey) or 60% conservation (light grey).Back to article page
