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...
متن کاملWorldwide dissemination and importance of the root-knot nematodes, Meloidogyne spp.
Root-knot nematodes are widely distributed throughout the world. Their distribution and economic importance are purported to be related to biological and environmental factors favorable to Meloidogyne spp. A scheme for comparing Meloidogyne spp. with two other genera of diverse biological characteristics is presented to support this hypothesis. It is further suggested that a probability index c...
متن کاملDNA Complexity of the Root-knot Nematode (Meloidogyne spp.) Genome.
Cot curves derived from renaturation kinetics of sheared denatured DNA indicated that the genome of six populations representing the four most common root-knot nematode species (Meloidogyne incognita, M. arenaria, M. javanica, and M. hapla) is composed of 20% repetitive and 80% nonrepetitive sequences of DNA. Cot curves were almost identical, indicating that all populations had a haploid genome...
متن کاملModelling Movements of Root-knot Nematodes Meloidogyne spp. Juveniles when Encumbered with Spores of Pasteuria penetrans
A system for monitoring movement of the free-living second stage juveniles of root-knot nematodes (Meloidogyne spp.) using digital image analysis is described. The method is based on the analysis of video sequences of movement of individual random nematodes encumbered with or without Pasteuria penetrans endospores. Software packages were used to grab video images, to process images and to monit...
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...
