Phylogenetic tree constructed using the maximum likelihood method based on concatenated sequences of ITS, GAPDH, RPB2, TEF1, Alt a 1, EndoPG, and OPA10-2 from Alternaria spp. Bootstrap support values (BS) and Bayesian posterior probability (PP) are given at the nodes (BS/PP). The strains from this study are marked in bold. Ex-type strains are indicated with ‘T’, representative strains are indicated with ‘R’. Alternaria alternantherae CBS 124392 is used as the outgroup taxon.
