Unrooted phylogenetic trees showing differences in gene expansion in D. stenobrocha and A. oligospora. A) Subtilisins (peptidase S08); B) Chitinases (GH18); C) Lectins. Red branches in file A and B identify genes only present in A. oligospora genome. Red branches in file C identify the fungal-fucose lectin coding genes and blue branches identify GalNAc-type lectin coding genes. Secreted enzymes are marked with red circles and differently expressed genes during nematode-trapping are marked with purple stars.
