Identity verification of Cercospora beticola isolates sequenced in this study. The phylogeny was constructed by Bayesian inference based on the sequences of five loci; ITS, act, cmd, his and tef1-α. Sequence alignments were produced using MAFFT v. 7 (Katoh & Standley 2013) (MrBayes v. 3.1.2; Ronquist & Huelsenbeck, 2003). Branches with posterior probability of 1.00 are thickened. The tree was rooted to C. zeaemaydis (CBS 117757).
