Molecular diagnosis of meloidogyne species.
نویسنده
چکیده
Genetic variation within nuclear and mitochondrial DNA of Meloidogyne species and host races has been evaluated for the development of root-knot nematode molecular diagnostics. This review summarizes the distinctive features of several useful DNA-based assays for plant-parasitic nematodes, focusing upon the direct application of these procedures for Meloidogyne detection, identification, and systematics.

Molecular Characterisation and Diagnosis of Root-Knot Nematodes (Meloidogyne spp.) from Turfgrasses in North Carolina, USA
Root-knot nematodes (Meloidogyne spp.) are the most common and destructive plant-parasitic nematode group worldwide and adversely influence both crop quality and yield. In this study, a total of 51 root-knot nematode populations from turfgrasses were tested, of which 44 were from North Carolina, 6 from South Carolina and 1 from Virginia. Molecular characterisation was performed on these samples...

Root-knot nematodes belonging to the genus Meloidogyne are the most economically important group of plant-parasitic nematodes. Thei r worldwide distribution, extensive host ranges, and interaction with other plant pathogens in diseas e complexes rank them among the top plant pathogens affecting the world's food supply (5). Even though only four Meloidogyne species M. incognita, M. javanica, M. ...
متن کاملThe threat of root-knot nematodes (Meloidogyne spp.) in Africa: a review
Meloidogyne species pose a significant threat to crop production in Africa due to the losses they cause on a wide range of agricultural crops. The direct and indirect damage caused by various Meloidogyne species results in delayed maturity, toppling, reduced yields and quality of crop produce, high costs of production and therefore loss of income. In addition, emergence of resistance-breaking M...
متن کاملAn early record of Meloidogyne fallax from Ireland
Root-knot nematodes, Meloidogyne spp., cause huge economic losses worldwide. Currently, three Meloidogyne spp. are present on the quarantine A2 list of EPPO, Meloidogyne chitwoodi, Meloidogyne fallax and Meloidogyne enterolobii. As a quarantine organism, Meloidogyne fallax has been detected in England and Northern Ireland on sport turf in 2011, and in England on leek in 2013. However, its prese...
متن کاملMolecular polymorphism and phylogenetic relationship in some Meloidogyne spp.: application to the taxonomy of Meloidogyne.
Proteins and various isozymes were investigated by direct analysis of single specimens in order to check molecular genetic variability, which is not rare in Meloidogyne species in spite of parthenogenetic reproduction. Variability was found in esterases, ocglycerophosphate, malate dehydrogenases, and some other proteins. Other loci appear monomorphic in the genus (for example, catalase), Distin...
