Influence 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 کاملMolecular characterization and functional analysis of the Nep1-like protein-encoding gene from Phytophthora capsici.
Phytophthora capsici is an aggressive plant pathogen that affects solanaceous and cucurbitaceous hosts. Nep1-like proteins (NLPs) are a group of effectors found particularly in oomycetes and considered important virulence factors. We identified an NLP gene (phcnlp1) from the highly virulent P. capsici strain Phyc12 that had an encoded polypeptide of 476-amino acid residues and a predicted molec...
متن کاملOligandrin. A proteinaceous molecule produced by the mycoparasite Pythium oligandrum induces resistance to Phytophthora parasitica infection in tomato plants.
A low-molecular weight protein, termed oligandrin, was purified to homogeneity from the culture filtrate of the mycoparasitic fungus Pythium oligandrum. When applied to decapitated tomato (Lycopersicon esculentum Mill. var. Prisca) plants, this protein displayed the ability to induce plant defense reactions that contributed to restrict stem cell invasion by the pathogenic fungus Phytophthora pa...
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...
