Abstract
Mutants of Pseudomonas putida (Agg−) that lack the ability to agglutinate with components present in washes of bean and cucumber roots showed limited potential to protect cucumber plants against Fusarium oxysporum f. sp. cucumerinum. However, a higher level of protection was observed against Fusarium wilt in cucumber plants coinoculated with the parental bacterium (Agg+), which was agglutinable. The Agg− mutants did not colonize the roots of cucumber plants as extensively as the Agg+ parental isolate did. In competition experiments involving bean roots inoculated with a mixture of Agg+ and Agg− bacteria, the Agg+ strains colonized roots to a greater extent than the Agg− cells did. These data suggest that the Agg+ phenotype provides additional interactions that aid in the beneficial character of P. putida.
