Fig. 1 Phylogenetic relationships among the 26 in A multigene phylogeny demonstrates that Tuber aestivum and Tuber uncinatum are conspecific

Fig. 1 Phylogenetic relationships among the 26 Tuber aestivumuncinatum isolates inferred using maximum likelihood (ML) and Bayesian inference (BI) from the concatenated nine-gene data set (4,722 bp total). The same topology was obtained for both phylogenetic analyses after 1,000 bootstrap replicates for ML and 2,000,000 generations for BI using the GTR+G model for both analyses. The tree is rooted with T. macrosporum and T. magnatum (in italics). Only bootstrap values higher than 70 % (number above) and posterior probabilities higher than 0.95 (number below) are indicated. The two pre-assigned types T. aestivum and T. uncinatum are indicated by A (boldface) and U, respectively. The geographic origin is indicated after for each sample ID
