  • Agricultural soils can host bacterial strains able to interfere with pathogenesis by protecting plant roots from fungal attack. Several Pseudomonas spp. produce a wide range of antibiotic compounds that can limit the growth of fungal pathogens. In this work, fluorescent pseudomonad strains isolated from different soils were identified according to a polyphasic approach. Molecular identification of the isolates was achieved by phylogenetic analyses of recA gene, while physiological profiles were evaluated by using API20NE and Biolog tests. All bacterial strains were characterized for antagonism by scoring the production of lytic exoenzymes, siderophores and antibiotics and by evaluating in vitro the inhibition of mycelial growth of four plant-pathogenic fungi. The ability to colonize plant surfaces was also assessed using swimming and swarming motility tests. The production of quorum-sensing signals was investigated, by using several bioreporter strains such as Chromobacterium violacearum strain CV026 and Agrobacterium tumefaciens strain NTL4. Five strains were evaluated for the control of Fusarium oxysporum f.sp. lycopersici and F. oxysporum f.sp. radicis lycopersici on tomato plantlets by using a predictive in vivo approach. Only those strains able to produce antibiotics and quorum-sensing signals performed well in protection of tomato plantlets. (literal)
