A 2-Cys peroxiredoxin in response to oxidative stress in the pine wood nematode, Bursaphelenchus xylophilus
The pine wood nematode, Bursaphelenchus xylophilus, is the causal agent of pine wilt disease that has devastated pine forests in Asia. Parasitic nematodes are known to have evolved antioxidant stress responses that defend against host plant defenses. In this study, the infestation of whitebark pine, Pinus bungean, with B. xylophilus led to a significant increase in plant hydrogen peroxide (H2O2...
متن کاملFunctional analysis of the cellulose gene of the pine wood nematode, Bursaphelenchus xylophilus, using RNA interference.
Cellulases are pathogenic substances suspected to be responsible for the development of the early symptoms of nematode disease. The pine wood nematode, Bursaphelenchus xylophilus (Parasitaphelenchidae), is the causal agent of pine wilt disease, which kills millions of pine trees. We used RNA interference (RNAi), a reverse genetic tool, to analyze the function of the endo-β-1,4-glucanase ge...
متن کاملPurification and characterization of recombinant endoglucanases from the pine wood nematode Bursaphelenchus xylophilus.
A family of endoglucanases belonging to glycoside hydrolase family (GHF) 45 have been isolated from the pine wood nematode Bursaphelenchus xylophilus. Here we describe the purification and characterization of the recombinant enzymes, named Bx-ENG-1, 2, and 3, expressed in Pichia pastoris. The respective molecular masses of purified Bx-ENG-1, 2, and 3 were estimated to be 18, 33-39, and 100-140 ...
متن کاملDeciphering the Molecular Variations of Pine Wood Nematode Bursaphelenchus xylophilus with Different Virulence
Bursaphelenchus xylophilus is the causative agent of pine wilt disease which has caused huge economic losses in many countries. It has been reported that two forms of pine wood nematodes existed in its native region, i.e., with strong virulence and weak virulence. However, little is known about the molecular differences between the two forms. To better understand their molecular variations, tra...
متن کاملObservations on the Morphology of the Pine Wood Nematode, Bursaphelenchus xylophilus.
Scans of slash pine wood chips infested with pine wood nematodes showed coiled aggregates of 5-10 nematodes in the axial resin canals, and 1-2 nematodes folded in the radial resin canals. Observations of the pine wood nematode by SEM showed the head to be offset with six labial lobes. A smaller circle of six inner lobes surrounded the stoma. A single labial sensillum was observed on each of the...
