Dual-Transcriptomic, Microscopic, and Biocontrol Analyses of the Interaction Between the Bioeffector Pythium oligandrum and the Pythium Soft-Rot of Ginger Pathogen Pythium myriotylum.

ABSTRACT: Biological control is a promising approach to suppress diseases caused by Pythium spp. such as Pythium soft rot of ginger caused by P. myriotylum. Unusually for a single genus, it also includes species that can antagonize Pythium plant pathogens, such as Pythium oligandrum. We investigated if a new isolate of P. oligandrum could antagonize P. myriotylum, what changes occurred in gene expression when P. oligandrum (antagonist) and P. myriotylum (host) interacted, and whether P. oligandrum could control soft-rot of ginger caused by P. myriotylum. An isolate of P. oligandrum, GAQ1, recovered from soil could antagonize P. myriotylum in a plate-based confrontation assay whereby P. myriotylum became non-vi
