Artificial induction of third-stage dispersal juveniles of Bursaphelenchus xylophilus using newly established inbred lines
The pine wood nematode, Bursaphelenchus xylophilus, is the causal agent of pine wilt disease. This nematode has two developmental forms in its life cycle; i.e., the propagative and dispersal forms. The former is the form that builds up its population inside the host pine. The latter is specialized for transport by the vector. This form is separated into two dispersal stages (third and fourth); ...
متن کاملNeutral Storage Lipid and Exit Behavior of Bursaphelenchus xylophilus Fourth- stage Dispersal Juveniles from their Beetle Vectors.
The J4 dispersal juvenile is a specialized life stage of the pinewood nematode, Bursaphelenchus xylophilus (Steiner &Buhrer) Nickle, that is transported by cerambycid beeries in the genus Monochamus. The nlediafion of J4 exit fronl beetle vectors is poorly understood. We hypothesized that decreasing neutral storage lipid in B. xylophilus J4 was related to behaviors leading to their exit from th...
متن کاملPathogenicity of Aseptic Bursaphelenchus xylophilus
Pine wilt is a disease of pine (Pinus spp.) caused by the pine wood nematode (PWN), Bursaphelenchus xylophilus. However, the pathogenic mechanism of pine wilt disease (PWD) remains unclear. Although the PWN was thought to be the only pathogenic agent associated with this disease, a potential role for bacterial symbionts in the disease process was recently proposed. Studies have indicated that a...
متن کاملPathotypes of the Pinewood Nematode Bursaphelenchus xylophilus.
An isolate of Bursaphelenchus xylophilus from Pinus sylvestris in Missouri infected and reproduced in 2-3-year-old seedlings of P. sylvestris and to some extent in seedlings of P. nigra. Wilting, however, occurred only in P. sylvestris. B. xylophilus isolated from P. strobus in Vermont infected and reproduced only in P. strobus seedlings. P. taeda seedlings were resistant to both of these isola...
متن کاملGenomic Differences among Pathotypes of Bursaphelenchus xylophilus.
Total genomic DNA from Bursaphelenchus xylophilus pathotypes MPSy-1 and VPSt-1 and from B. mucronatus was digested with restriction endonucleases. DNA fragments were electrophoretically separated, Southern blotted to nitrocellulose, and hybridized to genomic DNA from one of the isolates. The resulting hybridization patterns indicate genomic differences in repetitive DNA sequences among these po...
