Glycoside Hydrolase Genes Are Required for Virulence of Agrobacterium tumefaciens on Bryophyllum daigremontiana and Tomato.

ABSTRACT: Agrobacterium tumefaciens is a rhizosphere bacterium that can infect wound sites on plants. The bacterium transfers a segment of DNA (T-DNA) from the Ti plasmid to the plant host cell via a type IV secretion system where the DNA becomes integrated into the host cell chromosomes. The expression of T-DNA in the plant results in tumor formation. Although the binding of the bacteria to plant surfaces has been studied previously, there is little work on possible interactions of the bacteria with the plant cell wall. Seven of the 48 genes encoding putative glycoside hydrolases (Atu2295, Atu2371, Atu3104, Atu3129, Atu4560, Atu4561, and Atu4665) in the genome of A. tumefaciens C58 were found to play a role in virulence on tomato and
