FIGURE 1

Attachment of Agrobacterium tumefaciens strain C58 (A,C,E,G) and a UPP-deletion mutant of C58 (B,D,F,H) to quartz sand (A,B), polyester thread (C,D), yeast (Saccharomyces cerevisiae; C,F), and tomato root hairs (G,H) in a 1/10 dilution of MS medium containing a 1/20 dilution of AB minimal medium. Note the copious attachment of wild-type cells and the large decrease in attachment in a UPP deletion mutant. Approximately 106 bacteria per ml were incubated with the substrate for 24 h.
