Deciphering Plant-Induced Responses toward and Attacks in Two Grapevine Cultivars Colonized by the Root Biocontrol Oomycete, .

Two major diseases that affect grapevine leaves and berries are controlled by the oomycete . As the efficacy of biocontrol agents strongly depends on factors such as the trophic behaviors of pathogens and cultivar susceptibility, a two-disease approach was implemented to evaluate the activity of against (the necrotrophic fungus of gray mold) and (the biotrophic oomycete of downy mildew) on two grapevine cultivars with different susceptibilities to these two pathogens. The results show that grapevine root inoculation with significantly reduced and infection on the leaves of the two cultivars, but with differences.

The Biocontrol Root-Oomycete, , Triggers Grapevine Resistance and Shifts in the Transcriptome of the Trunk Pathogenic Fungus, .

The worldwide increase in grapevine trunk diseases, mainly esca, represents a major threat for vineyard sustainability. Biocontrol of a pioneer fungus of esca, , was investigated here by deciphering the tripartite interaction between this trunk-esca pathogen, grapevine and the biocontrol-oomycete, . When colonizes grapevine roots, it was observed that the wood necroses caused by were significantly reduced.

Draft Genome Sequence of the Root-Colonizing Fungus B97.

is one of the most beneficial microorganisms applied on diverse crops against biotic and abiotic stresses and acts also as a plant growth-promoting fungus. Here, we report the genome of B97, originating from a French agricultural soil and used as a biofertilizer that can tolerate abiotic stresses.

Draft Genome Sequence of Biocontrol Agent Pythium oligandrum Strain Po37, an Oomycota.

The oomycotaPythium oligandrumPo37 is used as a biocontrol agent of plant diseases. Here, we present the first draft of theP. oligandrumPo37 genome sequence, which comprises 725 scaffolds with a total length of 35.
