FIGURE 2.

Neighbor-joining (NJ) analysis revealing the phylogenetic relationships of endophytic fungi associated with Nervilia fordii. The NJ phylogenetic tree without outside groups includes a total of 169 fungal sequences, in which 85 sequences from our study, 84 reference sequences of close relatives from the NCBI database. Bootstrap support values are indicated for major nodes having values ≥50%. The names of 16 different groups are shown in bold letter such as: Glomerellales, Hypocreales, Diaporthales, Sordariales, Magnaporthales, Xylariales, Botryosphaeriale, Eurotiales, Cladosporiales, Muyocopronales, Chaetothyriales, Sordariomycetidae incertae sedis, Pleosporales, Polyporales, Corticiales, and Cantharellales. The solid square (■) represents the isolates with antimicrobial activity.
