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 35.9 Mb and 11,695 predicted protein-coding genes.

متن کاملInfluence of Pythium oligandrum biocontrol on fungal and oomycete population dynamics in the rhizosphere.
Fungal and oomycete populations and their dynamics were investigated following the introduction of the biocontrol agent Pythium oligandrum into the rhizosphere of tomato plants grown in soilless culture. Three strains of P. oligandrum were selected on the basis of their ability to form oospores (resting structures) and to produce tryptamine (an auxin-like compound) and oligandrin (a glycoprotei...
متن کاملCharacterisation of the early events in atypical tomato root colonisation by a biocontrol agent, Pythium oligandrum.
The specific oomycete-plant relationship established between a biological agent, Pythium oligandrum, and tomato (Lycopersicon esculentum Mill.) plants was examined over the first 48 h after inoculation of tomato roots with the antagonist. One of the most significant effects was the quick colonisation of cortical and vascular root areas by P. oligandrum (until 9 h post-inoculation); it was simil...
متن کاملCytological effects of cellulases in the parasitism of Phytophthora parasitica by Pythium oligandrum.
The ubiquitous oomycete Pythium oligandrum is a potential biocontrol agent for use against a wide range of pathogenic fungi and an inducer of plant disease resistance. The ability of P. oligandrum to compete with root pathogens for saprophytic colonization of substrates may be critical for pathogen increase in soil, but other mechanisms, including antibiosis and enzyme production, also may play...
