Sequencing and functional analysis of the genome of a nematode egg-parasitic fungus, Pochonia chlamydosporia.
Pochonia chlamydosporia is a worldwide-distributed soil fungus with a great capacity to infect and destroy the eggs and kill females of plant-parasitic nematodes. Additionally, it has the ability to colonize endophytically roots of economically-important crop plants, thereby promoting their growth and eliciting plant defenses. This multitrophic behavior makes P. chlamydosporia a potentially use...
متن کاملChitosan Increases Tomato Root Colonization by Pochonia chlamydosporia and Their Combination Reduces Root-Knot Nematode Damage
The use of biological control agents could be a non-chemical alternative for management of Meloidogyne spp. [root-knot nematodes (RKN)], the most damaging plant-parasitic nematodes for horticultural crops worldwide. Pochonia chlamydosporia is a fungal parasite of RKN eggs that can colonize endophytically roots of several cultivated plant species, but in field applications the fungus shows a low...
متن کاملThe Pochonia chlamydosporia Serine Protease Gene vcp1 Is Subject to Regulation by Carbon, Nitrogen and pH: Implications for Nematode Biocontrol
The alkaline serine protease VCP1 of the fungus Pochonia chlamydosporia belongs to a family of subtilisin-like enzymes that are involved in infection of nematode and insect hosts. It is involved early in the infection process, removing the outer proteinaceous vitelline membrane of nematode eggs. Little is known about the regulation of this gene, even though an understanding of how nutrients and...
متن کاملActivity of nematophagous fungi Pochonia chlamydosporia and Paecilomyces lilacinus on Dipylidium caninum egg capsules Atividade dos fungos nematófagos Pochonia chlamydosporia e Paecilomyces lilacinus sobre cápsulas de ovos de Dipylidium caninum
Nematophagous fungi are potential agents to be employed for biological control of helminthes. The ovicidal activity of the nematophagous fungi Pochonia chlamydosporia (isolates VC1 and VC4) and Paecilomyces lilacinus on egg capsules of Dipylidium caninum, a cestoda parasite of dogs, cats and men, was evaluated on Petri dishes cultures. One thousand of D. caninum egg capsules were placed onto Pe...
متن کاملExpression of serine proteases in egg-parasitic nematophagous fungi during barley root colonization.
Nematophagous fungi Pochonia chlamydosporia and P. rubescens colonize endophytically barley roots. During nematode infection, serine proteases are secreted. We have investigated whether such proteases are also produced during root colonization. Polyclonal antibodies against serine protease P32 of P. rubescens cross-reacted with a related protease (VCP1) of P. chlamydosporia, but not with barley...
