Abstract: The present disclosure provides a Brevundimonas strain as an endosymbiont of Verticillium dahliae, which is named Brevundimonas olei dahliae olei (B. olei) and deposited with the accession number of CCTCC NO: M 2020392. Morphological identification and diversity sequencing analysis confirm that the symbiont is B. olei. The effect of B. olei fermentation broth on growth and microsclerotia of Verticillium dahliae is explored through a co-cultivation experiment. Observations through electron microscope find that, with the increase of culture time and fermentation broth concentration, the Verticillium dahliae forms fewer conidia, its hyphae swell, rupture, and become abnormal in shape, and its microsclerotia gradually decrease and even disappear.
