Identification and Characterization of a Bursaphelenchus xylophilus (Aphelenchida: Aphelenchoididae) Thermotolerance-Related Gene: Bx-HSP90

Temperatures directly influence the distribution and intensity of pine wilt disease caused by the pine wood nematode, Bursaphelenchus xylophilus. To date, however, little is known about the causation and mechanism of this influence. The molecular chaperone HSP90 is a key component that contributes to survival in the abiotic stress response. In this study, we investigated the relationship betwee...

Bursaphelenchus xylophilus and B. mucronatus secretomes: a comparative proteomic analysis

The pinewood nematode, Bursaphelenchus xylophilus, recognized as a worldwide major forest pest, is a migratory endoparasitic nematode with capacity to feed on pine tissues and also on fungi colonizing the trees. Bursaphelenchus mucronatus, the closest related species, differs from B. xylophilus on its pathogenicity, making this nematode a good candidate for comparative analyses. Secretome profi...

Carbohydrate Catabolism in Populations of Bursaphelenchus xylophilus and in B. mucronatus.

Genotypically different host specific pathotypes of Bursaphelenchus xylophilus have been identified. These pathotypes elicit different responses in pines depending on susceptibility, tolerance, or resistance. Continued passage of some of these pathotypes on fungal cultures leads to conversion to nonparasitic populations. These populations metabolize carbon substrates to ethanol by an anaerobic ...

Temperature-mediated Behavioral Relationships in Bursaphelenchus xylophilus, B. mucronatus, and Their Hybrids.

The influence of temperature on reproduction and movement was examined for seven geographic isolates of Bursaphelenchus xylophilus, three of B. mucronatus, and two of their interspecific hybrids. All nematode isolates tended to be more active and fecund the higher the temperature, with the isolates of B. xylophilus reaching a reproductive peak at higher temperatures than isolates of B. mucronat...

New Insights into the Phylogeny and Worldwide Dispersion of Two Closely Related Nematode Species, Bursaphelenchus xylophilus and Bursaphelenchus mucronatus

The pinewood nematode, Bursaphelenchus xylophilus, is one of the greatest threats to coniferous forests worldwide, causing severe ecological damage and economic loss. The biology of B. xylophilus is similar to that of its closest relative, B. mucronatus, as both species share food resources and insect vectors, and have very similar morphological characteristics, although little pathogenicity to...
