Fig. 2From: Bacteria of the genus Rhodopseudomonas (Bradyrhizobiaceae): obligate symbionts in mycelial cultures of the black truffles Tuber melanosporum and Tuber brumale PhyML phylogenetic tree based on nearly complete 16S rRNA (1330 bp) sequences of 12 Tuber spp. associated bacterial strains aligned with Rhodopseudomonas spp. type strains (T) and related strains, including uncultured Bradyrhizobium sp. clones from Tuber borchii and Tuber magnatum ascocarps. Only branch support probabilities (estimated with the approximate likelihood-ratio test) higher than 0.70 are given at the branching points. Gaps were not considered. Scale indicates 2 % sequence divergence. Blastochloris sulfoviridis was chosen as an outgroupBack to article page
