Colonization pattern of Salmonella on roots. S. Typhimurium 14028s GFP on root of lettuce (A,B) and corn salad (C,D) grown under sterile conditions. Plants were inoculated with GFP-expressing Salmonella for 3 days. Maximum projection images (A,C) and orthogonal scalings (B,D) indicate nucleus in blue, cell walls in red and GFP-labeled Salmonella cells in green. Orthogonal scalings show S. Typhimurium 14028s GFP cells in the cavity between primary and secondary root (B,D). The scale bars indicate 30 μm (A,B) and 40 μm (C,D).
