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...
Mitochondrial haplotypes reveal olive fly (Bactrocera oleae) population substru...
van Asch, Barbara; Pereira-Castro, Isabel; Rei, Fernando; Costa, LuisThe olive fly (Bactrocera oleae) is the most important olive tree (Olea europaea) pest. In the Mediterranean basin, where 98 % of its main hosts are concentrated,it causes major agricultural losses, due to its negative effect on production and quality of both olive and olive oil. Previous phylogeographic analyses have established that Mediterranean olive fly populations are distinct from other Old World populat...
