Abstract :
[en] In vivo experiments on tomato (Lycopersicon esculentum) roots have been performed: drench of 10-day hydroponic cultures with bacterial suspensions. A second identical treatment was applied one week later and after 30 days of culture, the plants were collected and the bacteria detached from a precise weight of roots were diluted, plated and counted. The mutant devoid of both GalM and PBP4a (encoded by the galM and dacC operon) is affected in its capacity to colonize the tomato roots.
