Fig. 3

Alignment of isolated and characterized cysteine-rich antifungal proteins from filamentous ascomycetes (a). Based on the amino acid similarity they are separated into three different groups (PAF-, BP-, and NFAP2-cluster proteins), and further four different subgroups are distinguishable in the PAF-cluster proteins. Maximum likelihood tree of isolated PAF- and BP-cluster proteins, and NFAP2 and its homologs detected through BLAST searches in published fungal genomes (b). ML bootstrap values >50 % are shown next to branches, all bootstrap values are available on Additional file 1: Fig. S3. The antifungal proteins included in the phylogenetic analyses separated into three major clades, Group 1 (BP-cluster proteins, blue), Group 2 (PAF-cluster proteins, yellow) and Group 3 (NFAP2 and its homologs, green). The presence of four different subgroups of PAF-cluster proteins is also supported by the phylogenetic tree. Abbreviations of isolated and characterized proteins: AcAFP, Aspergillus clavatus VR1 antifungal protein (Acc. No.: A1CSS4), AcAMP, Aspergillus clavatus ES1 antimicrobial peptide (Acc.

No.: D4YWE1); NFAP2, Neosartorya fischeri NRRL 181 antifungal protein 2 (Acc. No.: A1DBL3); PAF, Penicillium chrysogenum Q176 antifungal protein (Acc.
