Abstract A survey of Meloidogyne in La Vera (Spain) was carried out during October 1995 and 1997. Isozyme electrophoresis (A-EST, MDH, CAT, GPI, DIA, GOT and SOD) was performed for each nematode isolate, each of which was cultured from an egg mass. In 1995 seven isolates of M. incognita, two of M. javanica and 75 of M. arenaria were found,...

Tandemly repeated sequences known as satellite DNA (satDNA) generally exhibit complex evolutionary patterns of concerted evolution in which mutations are homogenized and fixed in a stochastic process of molecular drive. Here, the nucleotidic variability of the Mspl satDNA family of the pinewood nematode Bursaphelenchus xylophilus is analyzed in...

The Pine Wood Nematode (PWN) Bursaphelenchus xylophilus is a severe forest pathogen in countries where it has been introduced and is considered a worldwide quarantine organism. In this study, protein markers for differentiating populations of this nematode were identified by studying differences among four selected Iberian and one American...
