Figure 2From: The dirigent multigene family in Isatis indigotica: gene discovery and differential transcript abundanceNeighbor-Joining (NJ) phylogenetic trees of 19 Ii DIRs. The values on the branches are bootstrap proportions, which indicated the percentage values for obtaining this particular branching in 1000 repetitions of the analysis. The lengths of branches are proportional to evolutionary distances between species.Back to article page
