    Aims: To investigate the interaction between cauliflower and the isolate
    Verticillium Vt305, obtained from a field suppressive to Verticillium wilt of
    cauliflower, and to evaluate the ability of Verticillium Vt305 to control
    Verticillium wilt of cauliflower caused by V. longisporum.
    Methods and Results: Single and combined inoculations of Verticillium Vt305
    and V. longisporum were performed on cauliflower seedlings. Symptom
    development was evaluated, and fungal colonization was measured in the
    roots, hypocotyl and stem with real-time PCR. No symptoms were observed
    after single inoculation of Verticillium Vt305, although it colonized the plant
    tissues. Pre-inoculation of Verticillium Vt305 reduced symptom development
    and colonization of plant tissues by V. longisporum.
    Conclusions: Verticillium Vt305 is an endophyte on cauliflower plants and
    showed effective biological control of V. longisporum in controlled conditions.
    Significance and Impact of the Study: This work can contribute to the
    development of a sustainable control measure of V. longisporum in Brassicaceae
    hosts, which is currently not available. Additionally, this study provides evidence
    for the different roles of Verticillium species present in the agro-ecosystem.
