摘要: Resistance to root-knot nematodes in tomato is conferred by the Mi resistance gene three most important species of Meloidogyne: M. arenaria, incognita, and javanica. Nevertheless, unable inhibit reproduction selected naturally Mi-virulent populations nematodes. As pathogenicity assays are time consuming, molecular markers were developed for easy identification Meloidogyne. The sequence characterized amplified region-Meloidogyne virulence locus (MVC) marker reported differentiate Mi-avirulent from populations. This was used compare acquired javanica Spain. original develop MVC included as control reference. Results showed that this did not amplify genomic DNA extracted single juveniles or females any tested either Spain Japan. In silico analyses performed with recently published complete genome indicated correlated a eukaryotic organism but several betaproteobacteria genus family Comamonadaceae.
