[Abstract] The present protocol to visualize living bacteria at the pore level of cauliflower hydathodes is simple and trained users in confocal microscopy can execute it successfully. It can be easily adapted to capture images with other plant-microorganism interactions at the leaf surface and should be useful to obtain important information on pore and ...

[Abstract] Xanthomonads can scavenge iron from the extracellular environment by secreting the siderophores, which are synthesized by the proteins encoded by xss (Xanthomonas siderophore synthesis) gene cluster. The siderophore production varies among xanthomonads in response to a limited supply of iron where Xanthomonas ...

[Abstract] Gram-negative bacteria naturally release outer membrane vesicles (OMVs) to the surrounding environment. OMVs contribute to multiple processes, such as cell-cell communication, delivery of enzymes and toxins, resistance to environmental stresses and pathogenesis. Little is known about OMVs produced by plant-pathogenic bacteria, and their ...
