Adhesion of ectomycorrhizal bacteria to plant cells: an in vitro evidence.

In this study we have investigated, by combining microbial and microscopical techniques, the adhesion ability of bacteria present in Tuber borchii ectomycorrhizosphere. Our data demonstrate that a common pool of bacteria - Pseudomonas, Bacillus, Micrococcus and Moraxella - occurs in all ectomycorrhizal homogenates and that most of these bacteria are able to attach in vitro to plant cells.
