Figure 2From: The type III protein secretion system contributes to Xanthomonas citri subsp. citri biofilm formation Confocal laser scanning microscopy analysis of X. citri and hrpB − strains grown statically. GFP-expressing X. citri and hrpB − strains cultured statically in vitro were analyzed by confocal laser scanning microscopy, serial images were taken at 0.5 μm distances (vertical z-stack). Z represents the ZX axis projected images. At the XY images, white arrows point to X. citri clusters of aggregated cells.Back to article page
