Nematicidal Bacteria Associated to Pinewood Nematode Produce Extracellular Proteases
Bacteria associated with the nematode Bursaphelenchus xylophilus, a pathogen of trees and the causal agent of pine wilt disease (PWD) may play a role in the disease. In order to evaluate their role (positive or negative to the tree), strains isolated from the track of nematodes from infected Pinus pinaster trees were screened, in vitro, for their nematicidal potential. The bacterial products, f...
متن کاملBacteria can mobilize nematode-trapping fungi to kill nematodes
In their natural habitat, bacteria are consumed by bacterivorous nematodes; however, they are not simply passive preys. Here we report a defensive mechanism used by certain bacteria to mobilize nematode-trapping fungi to kill nematodes. These bacteria release urea, which triggers a lifestyle switch in the fungus Arthrobotrys oligospora from saprophytic to nematode-predatory form; this predaciou...
متن کاملInhibition of Tea Root Lesion Nematode, Pratylenchus Loosi, by rhizospher bacteria
Root-lesion disease, which is caused by Pratylenchus loosi , is one of the most important diseases currently impacting Iran tea plantations. This disease causes great economic crop impacts. Northern provinces, which supply much of Iran’s tea production, have been especially hard impact by root-lesion disease.The purpose of this study was to biological control the nematodes as one of the main se...
متن کاملCharacterization of Bacteria Associated with Pinewood Nematode Bursaphelenchus xylophilus
Pine Wilt Disease (PWD) is a complex disease integrating three major agents: the pathogenic agent, the pinewood nematode Bursaphelenchus xylophilus; the insect-vector Monochamus spp.; and the host pine tree, Pinus sp. Since the early 80's, the notion that another pathogenic agent, namely bacteria, may play a role in PWD has been gaining traction, however the role of bacteria in PWD is still unk...
متن کاملFeeding of the Nematode Acrobeloides nanus on Bacteria.
Information on the effect of bacteria-feeding nematodes on bacterial populations in the soil is sparse. We have isolated, cultured, and microscopically examined bacteria and nematodes coexisting within an agricultural soil and have studied their feeding relationship. The bacterium Pseudomonas corrugata isolate 2140R is a biocontrol agent against the pathogenic fungus Gaeumannomyces graminis var...
