Bursaphelenchus fungivorus from Pinus pinaster bark in Portugal
Fonseca, L.; Cardoso, J. M. S.; Moron-Lopez, J.; Abrantes, I. M. O.Bursaphelenchus fungivorus is reported for the first time in Portugal, identified as associated with Pinus pinaster bark and characterized on the basis of morphological and morphometrical characters for this species. Species identification was confirmed using restriction fragment length polymorphism analysis and sequencing of the internal transcribed spacer (ITS) regions of ribosomal DNA. Intraisolate genetic v...
Assessment of the Geographic Origins of Pinewood Nematode Isolates via Single N...
Figueiredo, Joana; Simões, Maria José; Gomes, Paula; Barroso, Cristina; Pinho, Diogo; da Conceição, I. L. P. M.; Fonseca, Luís; Abrantes, I. M. O.The pinewood nematode, Bursaphelenchus xylophilus, is native to North America but it only causes damaging pine wilt disease in those regions of the world where it has been introduced. The accurate detection of the species and its dispersal routes are thus essential to define effective control measures. The main goals of this study were to analyse the genetic diversity among B. xylophilus isolates from different...
Nematicidal Bacteria Associated to Pinewood Nematode Produce Extracellular Prot...
Paiva, Gabriel; Proença, Diogo Neves; Francisco, Romeu; Veríssimo, P.; Santos, Susana S.; Fonseca, Luís; Abrantes, I. M. O.; Morais, P. V.Bacteria associated with the nematode Bursaphelenchus xylophilus, a pathogen of trees and the causal agent of pine wilt disease (PWD) may play a role in the disease. In order to evaluate their role (positive or negative to the tree), strains isolated from the track of nematodes from infected Pinus pinaster trees were screened, in vitro, for their nematicidal potential. The bacterial products, from strains more ...
