Evolutionary profiles of β-glucan synthase (A) and XXT (B) genes in green plants. A: CSL C (β-glucan synthase) and CSL A (β-mannan and β-glucomannan synthases) PoGOs. The topologies were obtained by Neighbor-Joining method with genetic distances calculated by p-distance. The bootstrap values higher than 50% are shown for 1000 replicates along with Maximum-likelihood (ML) aLRT values higher than 0.50 (in the figure [NJ/ML]). Accession numbers for all genes in the trees are described in Additional File 12 for β-Glucan Synthase and Additional File 14 for XXT. The detailed trees are shown in Additional File 11 for β-Glucan Synthase and Additional File 13 for XXT.
