Pathogenicity 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 کاملPathogenicity of the pinewood nematode, Bursaphelenchus xylophilus, to Japanese larch, Larix kaempferi, seedlings.
Pathogenicity of the pine wood nematode, Bursaphelenchus xylophilus, to Japanese larch, Larix kaempferi, seedlings was tested with inoculation experiments under nursery conditions. Water suspensions of nematodes (mixed stages cultured on Botrytis cinerea or dispersal fourth-stage juveniles (DJ4) extracted from the adult Japanese pine sawyer, Monochamus alternatus) were injected into the stems o...
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...
متن کاملGenetic diversity of ITS sequences of Bursaphelenchus xylophilus.
The sequence variation of internal transcribed spacer (ITS) regions of ribosomal DNA has been routinely used for species identification and species-level phylogeny of the pinewood nematode, Bursaphelenchus xylophilus. In this study, the intraspecies ITS genetic diversity of B. xylophilus was evaluated. Three pinewood nematode isolates from the United States, Japan, and Portugal were used for po...
