Figure 1From: Phylogeny and expression profiling of CAD and CAD-like genes in hybrid Populus (P. deltoides × P. nigra): evidence from herbivore damage for subfunctionalization and functional divergencePhylogenetic tree of CAD/CAD-like genes. Numbers above branches refer to bootstrap values. Values that were below 50 were not reported. Brackets highlight the three classes of CAD/CAD-like genes.Back to article page
