Interspecific hybridization between Bursaphelenchus xylophilus and Bursaphelenchus mucronatus

Journal of Forestry Research, 2018
Bursaphelenchus xylophilus is the pathogen that causes pine wilt disease, which has greatly damaged forests and ecosystems in countries of East Asia and Europe. Bursaphelenchus mucronatus is closely related to B. xylophilus in morphology and host plant specificity.

Embryology and Cytology of Bursaphelenchus xylophilus

2008
Because of their small size, availability, simple and transparent body, and reproducible development nematodes have been popular organisms for studying animal development since the nineteenth century. The many important events in embryogenesis, such as fertilization, meiosis, pronuclear meeting, and chromosome-based sex-determination were discovered as

Population Ecology of Bursaphelenchus xylophilus

2008
Population ecology is the study of biological populations, and it includes diverse subfields: population dynamics concerns the size and structure of a population and examines the effects of environmental factors on it. In the study of population genetics, the changes of allele frequencies within populations and their distribution are especially ...

Developmental Biology and Cytogenetics of Bursaphelenchus xylophilus

2008
The pinewood nematode, Bursaphelenchus xylophilus, reproduces bisexually: a haploid sperm fertilizes a haploid oocyte, and the two pronuclei rearrange, move together, fuse, and begin diploid development. Early embryonic events taking place in the B. xylophilus embryo are similar to those of Caenorhabditis elegans, although the anterior-posterior axis ...

Satellite DNA as a Versatile Genetic Marker for Bursaphelenchus xylophilus

2008
Bursaphelenchus xylophilus is causal agent of the pine wilt disease, one of the major conifer diseases worldwide. This nematode is a quarantine organism in the European Union, where it has recently been discovered in a restricted area in Portugal. In our laboratory, research has been developed to characterize the genetic diversity of the nematode, and ...

First report of Bursaphelenchus xylophilus in Portugal and in Europe

Nematology, 1999
AbstractA survey of aphelenchid nematodes (Nematoda: Aphelenchida) associated with maritime pine, Pinus pinaster, was conducted in Portugal in 1996 and 1999. A Bursaphelenchus species has been identified for the first time in the Iberian Peninsula. B. xylophilus is reported for the first time in Europe.

The pinewood nematode, Bursaphelenchus xylophilus

2012
According to the European Plant Protection Organization, the pinewood nematode (PWN), Bursaphelenchus xylophilus is a quarantine organism at the top of the list of the pathogenic species. PWN may be found in North America (Canada, USA and Mexico) and in East Asia (Japan, Korea, China and Taiwan) and has a highly destructive capability towards conifers,

Behavioural features of Bursaphelenchus xylophilus in the mating process

Nematology, 2014
The pine wood nematode (PWN), Bursaphelenchus xylophilus, is able to produce hundreds of thousands of offspring in a short time. Its mating behaviour might play a basic role in this marked fecundity. We investigated the features of the mating behaviour of B. xylophilus using long-time microscope video and repeated observations.

The Enlargement of the xylophilus Group in the Genus Bursaphelenchus

2008
The xylophilus group of the genus Bursaphelenchus can be clearly distinguished from other species of the genus by the presence of four lateral lines, the presence of a vulval flap in females, a characteristic shape of the male spicules and the arrangement of the seven caudal papillae.
