Figure F1. Neighbor-joining phylogenetic tree based on partial 28S rRNA gene sequences (464 bp) showing the position of the isolate NPf1 among representative species of the order Chaetothyriales. Bootstrap analyses were performed (100 replicates), and only bootstrap values >50% are shown. Solid dots = spp. which are reported to be isolated from terrestrial rocks (Ruibal et al., 2008).
