Abstract
The invention is a method for identifying and cloning bacterial genes that are responsive to the presence of a plant host, comprising mutating a bacterial culture with a transposon containing a promoterless marker gene, exposing the bacterial mutants to root exudates, other plant-derived substances or plants, and identifying mutants that have a transposon-associated gene inducible by the plant. These mutants may be used to clone and characterize the promoters and the associated wild-type bacterial genes responsive to the plant.
