Genetic Determinants of Antagonistic Interactions and the Response of New Endophytic Strain Serratia quinivorans KP32 to Fungal Phytopathogens.

ABSTRACT: Fungal phytopathogens are challenging to control due to their penetration into plant tissues. Therefore, plant-colonizing bacteria could serve as an excellent weapon in fighting fungal infections. In this study, we aim to determine the biocontrol potential of the new endophytic strain Serratia quinivorans KP32, isolated from the roots of Petroselinum crispum L.; identify the related mechanisms; and understand the basis of its antagonistic interaction with taxonomically diverse fungi at the molecular level. The KP32 strain presented biological activity against Rhizoctonia solani, Colletotrichum dematium, Fusarium avenaceum, and Sclerotinia sclerotiorum, and its ability to inhibit the growth of the phytopathogens was found to be mediated by a broad s
