Genome diversity in the genera Fructobacillus, Leuconostoc and Weissella determ...
Chelo, Ivo M.; Zé-Zé, Líbia; Tenreiro, RogérioPulsed-field gel electrophoresis analysis of chromosomal single and double restriction profiles of 17 strains belonging to three genera of ‘Leuconostocaceae’ was done, resulting in physical and genetic maps for three Fructobacillus, six Leuconostoc and four Weissella strains. AscI, I-CeuI, NotI and SfiI restriction enzymes were used together with Southern hybridization of selected probes to provide an assessmen...
Species of Bursaphelenchus Fuchs, 1937 (Nematoda: Parasitaphelenchidae) associa...
Penas, Ana Catarina; Correia, Petra; Bravo, Maria Antónia; Mota, Manuel; Tenreiro, RogérioSummary – Species of Bursaphelenchus associated with maritime pine, Pinus pinaster, from Portugal – within and outside the quarantine restricted demarcated zone of B. xylophilus – are described and characterised both morphologically (LM and SEM) and with the use of molecular biology (ITS-RFLP).A new staining method for spicules is proposed. Species include B. hellenicus, B. hylobianum, B. leoni, B. pinophilus, ...
