Phylogenetic tree of xyloglucan endotransglucosylase/hydrolases (XTHs) from different species. FvXTH9 and FvXTH6 protein sequences (indicated by arrows) were aligned with XTHs from Arabidopsis thaliana (At), Brachypodium distachyon (Bd), Equisetum fluviatile (Ef), Fragaria chiloensis (Fc), Fragaria vesca (Fv), Malus × domestica (Md), Populus tremula × Populus tremuloides (Ptt), Solanum lycopersicum (Sl) and Tropaeolum majus (Tm). EfHTG (hetero‐trans‐β‐glucanase) and BdXTH8 possess mixed‐linkage glucan:xyloglucan endotransglucosylase (MXE) activity, whereas AtXTH3 shows cellulose:xyloglucan endotransglucosylase (CXE) activity (indicated by asteriks). The phylogenetic tree was constructed by the neighbour‐joining method with 5000 bootstrap replications using mega 7. The GenBank accession numbers are indicated in the figure. Groups I/II, IIIA and IIIB show the different groups of XTHs.
