Phylogenetic analysis based on EF1-a sequences from Beauveria bassiana. The MP tree was generated by parsimony analysis after heuristic searches (TBR option). A bootstrap full heuristic analysis, with bootstrap intervals from 1000 replications and nodes supported in >50% of bootstrap replicates, was generated using the PAUP 4.0 program. Branch lengths are proportional to the number of changes. Eleven sequence types identified from 56 B. bassiana isolates, of which 52 were sampled in Spain (bolded), were aligned with 18 GenBank B. bassiana s.s., B. brongniartii and B. cf. bassiana (clade C) sequences, indicated by accession numbers as in previous works [7,8]. B. bassiana s.s. EF1-α sequences representing European subgroups  are marked with an asterisk. Reference isolates from countries different to Spain, are referred to as: Eu-1 (KVL0376 from Denmark and ARSEF1628 from Hungary), Eu-3 (KVL0373 from Denmark and ARSEF1185 from France), Eu-4 (KVL03114 from Denmark and ARSEF1848 from Belgium), Eu-5 (KVL0392 and KVL03112 from Denmark), Eu-6 (KVL0384 from Denmark and 815 from France), Eu-7 (Bb45 from Portugal), Wd-1 (296 and 344 from USA), Wd-2 (681 from Romania, 792 from USA, Bb55 from Georgia and Bb56 from Greece), C1 (4933 from France and Bb57 from Poland), C2 (812 from France) and B. brogniartii (KVL0392 from Denmark and 4384 from China). Cordyceps cf. scarabaeicola (EFCC 2533) was the outgroup. Identifiers of EF1-α subgroups and intron configuration patterns are indicated.
