Visualization of clusters of Burkholderia sensu lato spp. associated with secretory trichomes on leaf acumens of Dioscorea bulbifera (potato yam) by DOPE-FISH/CLSM microscopy. EUBmix and Burkho probes were applied onto leaf acumens sequentially and the upper surface of the acumen, which is densely covered with secretory trichomes, was visualized (A). Burkholderia s.l. spp. (white arrows), labeled with both EUBmix (green channel) and Burkho probes (yellow channel), can be observed clustering on the sides of, or in between, secretory trichomes (st, orange arrows) emerging from the upper epidermis (ue, green arrows) of the leaf acumen. In panel (B) a high-resolution image of a cluster on the side of a trichome can be seen, all bacterial cells shown are labeled with the Burkholderia s.l. specific probe.
