Abstract

Rhizobium leguminosarum quorum-sensing mutants are enhanced for biofilm production whereas a protein secretion mutant is defective for biofilm formation. This proposal will use the R. leguminosarum genome sequence to identify candidate genes predicted to be involved in bacterial attachment and growth on surfaces. Targeted and random mutagenesis will identify mutants defective for, and enhanced for biofilm formation. The expression pattern of the identified genes will be analysed in situ on inert surfaces and on legume roots using promoter-gfp fusions. Genes and proteins induced specifically in biofilms will be identified. Analysis of mutant phenotypes on inert surfaces and legume roots will determine the factors required for root attached growth.
