Molecular characterization of Portuguese populations of the pinewood nematode B...
Valadas, Vera; Laranjo, Marta; Mota, Manuel; Oliveira, SolangeBursaphelenchus xylophilus is the causal agent of pine wilt disease and a worldwide pest with high economic impact. Since its first diagnosis in Portugal in 1999, it has been subjected to quarantine measures with impact on forest health and ecosystem stability, significantly affecting international trade of wood products. The disease was detected in the north and centre of continental Portugal and, since 2008, ...
Efficacy of sulfuryl fluoride against the pinewood nematode, Bursaphelenchus xy...
Bonifacio, Luis; Sousa, Edmundo; Naes, Pedro; Inacio, Maria; Henriques, Joana; Mota, Manuel; Barbosa, Pedro; Drinkall, Mike; Buckley, StanislasBACKGROUND: The pinewood nematode (PWN) Bursaphelenchus xylophilus is an important conifer disease worldwide. It is the direct cause of the death of millions of pines in south-east Asia (mainly Japan, China and Korea) and has been established in Portugal since 1999. The phasing out of methyl bromide has created an urgent need for alternative treatment of wood packagingmaterials. The effect of sulfuryl fluoride ...
Survey of the genus Bursaphelenchus Fuchs, 1937 (Nematoda: Aphelenchoididae) in...
Calin, M; Vieira, Paulo; Costache, C; Braasch, H; Gu, J; Wang, J; Mota, ManuelAn overview of the occurrence of species of the genus Bursaphelenchus in Romania is presented. The data is based on recent surveys conducted for the first time throughout the country, to monitor and evaluate the potential entry of the pine wood nematode, Bursaphelenchus xylophilus. Wood samples were collected from declining trees, woodprocessing companies and imported wood packaging material. Of the 895 wood sa...
On the genus Bursaphelenchus Fuchs, 1937 (Nematoda: Parasitaphelenchinae) assoc...
Cermák, V; Vieira, Paulo; Gaar, V; Cudejková, M; Foit, J; Zouhar, M; Douda, O; Mota, ManuelAn overview of the genus Bursaphelenchus in the Czech Republic is presented, based on a recent survey for monitoring the presence of the pinewood nematode, Bursaphelenchus xylophilus, as well as on previous reports of this genus in the country. In addition, we provide a morphological and molecular characterization of four Bursaphelenchus species (B. eremus, B. pinophilus, B. vallesianus and B. borealis) found d...
Bioactivity against Bursaphelenchus xylophilus: Nematotoxics from essential oil...
Faria, Jorge; Barbosa, Pedro; Bennett, Richard; Mota, Manuel; Figueiredo, CristinaThe Portuguese pine forest has become dangerously threatened by pine wilt disease (PWD), caused by the pinewood nematode (PWN), Bursaphelenchus xylophilus. Synthetic chemicals are the most common pesticides used against phytoparasitic nematodes but its use has negative ecological impacts. Phytochemicals may prove to be environmentally friendly alternatives. Essential oils (EOs) and decoction waters, isolated fr...
First Insights into the Genetic Diversity of the Pinewood Nematode in Its Nativ...
Mallez, Sophie; Castagnone, Chantal; Espada, Margarida; Vieira, Paulo; Eisenback, Jonathan D.; Mota, Manuel; Guillemaud, ThomasThe pinewood nematode, Bursaphelenchus xylophilus, native to North America, is the causative agent of pine wilt disease and among the most important invasive forest pests in the East-Asian countries, such as Japan and China. Since 1999, it has been found in Europe in the Iberian Peninsula, where it also causes significant damage. In a previous study, 94 pairs of microsatellite primers have been identified in si...
The mitochondrial genome of the pinewood nematode (Bursaphelenchus xylophilus) ...
Moreira, Claudia; Asch, Barbara; Fonseca, Luis; Pereira-Castro, Isabel; Silva, Raquel; Azevedo, Luísa; Mota, Manuel; Abrantes, Isabel; Amorim, AntónioThe pinewood nematode (PWN) Bursaphelenchus xylophilus is the causative agent of pine wilt disease and the greatest biological threat to conifer forests worldwide. Here we describe the near-complete mitochondrial DNA (mtDNA) sequence (12,945 bp) of the PWN lineage recently introduced in Europe. The absence of polymorphisms across the mtDNA of three Portuguese isolates suggests that a single mitochondrial lineag...
New Insights into the Phylogeny and Worldwide Dispersion of Two Closely Related...
Pereira, Filipe; Moreira, Claudia; Fonseca, Luis; Asch, Barbara; Mota, Manuel; Abrantes, Isabel; Amorim, AntónioThe 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 conifers has bee...
On the track of Bursaphelenchus pinophilus Brzeski and Baujard, 1997 (Nematoda:...
Vieira, Paulo; Mota, ManuelThis is the first report and characterization of Bursaphelenchus pinophilus in Portugal. This species was isolated from a young dying Pinus pinaster tree located in Valverde, in the Alentejo region. Nematodes were identified using several morphological diagnostic characters for this species (male spicule structure, number of lateral incisures, number and distribution of the male papillae, presence of female vul...
Ectopic expression of Kip-related proteins restrains root-knot nematode-feeding...
Vieira, Paulo; Escudero, Carmen; Rodiuc, Natalia; Boruc, Joana; Russinova, Eugenia; Glab, Nathalie; Mota, Manuel; Veylder, Lieven; Abad, PierreThe development of nematode feeding sites induced by root-knot nematodes involves the synchronized activation of cell cycle processes such as acytokinetic mitoses and DNA amplification. A number of key cell cycle genes are reported to be critical for nematode feeding site development. However, it remains unknown whether plant cyclin-dependent kinase (CDK) inhibitors such as the Arabidopsis interactor/inhibitor ...
