Figure 5From: Cultivation reveals physiological diversity among defensive ‘Streptomyces philanthi’ symbionts of beewolf digger wasps (Hymenoptera, Crabronidae) Phylogenetic tree of opportunistic bacteria isolated from different beewolf samples. Low-abundance bacteria (first dilution) were isolated from (i) males’ antennae (blue boxes) and (ii) females’ antennae (green boxes); high-abundance bacteria (102-104 CFU/sample) isolated from females’ antennae are shown in red boxes. The tree was reconstructed based on an alignment of 725 bp of 16S rRNA genes using Neighbour-Joining within MEGA version 5. Numbers at nodes indicate bootstrap values greater than 50%.Back to article page
