The biocontrol agent Pseudomonas chlororaphis subsp. aureofaciens M71 originates natural mutants impaired in the ability to control Fusarium oxysporum f. sp. radicis-lycopersici on tomato

Abstract: Pseudomonas chlororaphis subsp. aureofaciens M71 differentiated three natural mutants distinguishable for morphological traits. P. chlororaphis subsp. aureofaciens M71 mutants were impaired in persisting on tomato roots and controlling tomato crown rot. Mutants were characterised by a reduced ability in production of autoinducer signals and antibiotics.
