DNA 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 کاملInfluence of Root Knot Nematode (Meloidogyne spp.) on Phenolic Acid Profile in Root of Tomato (Solanum lycopersicum L.)
Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops worldwide, owing to its high nutritive value and diversified use. Plant parasitic nematodes are important pests of tomato and cause huge economic losses (Bird and Kaloshian, 2003). India is the second largest tomato growing country having cultivation area of 8.8 lakh ha with production of 18.23 mmt with productivity 20....
متن کاملTranscriptional Changes of the Root-Knot Nematode Meloidogyne incognita in Response to Arabidopsis thaliana Root Signals
Root-knot nematodes are obligate parasites that invade roots and induce the formation of specialized feeding structures. Although physiological and molecular changes inside the root leading to feeding site formation have been studied, very little is known about the molecular events preceding root penetration by nematodes. In order to investigate the influence of root exudates on nematode gene e...
متن کاملDNA Isolation and GC Base Composition of Four Root-knot Nematode (Meloidogyne spp.) Genomes.
Phenol extraction and cesium trifluoroacetate ultracentrifugation were compared for efficiency in the extraction of DNA from eggs and second-stage juveniles of four species of Meloidogyne. The second method proved to be more satisfactory in that it yielded larger amounts of DNA, shortened the extraction period, and reduced sample handling by eliminating phenol and ether extraction and RNAse tre...
متن کاملManagement of root knot nematode (Meloidogyne incognita ) in Indiana soybeans
Perla, David E. M.S., Purdue University, August, 2014. Management of Root Knot Nematode (Meloidogyne incognita) in Indiana Soybeans. Major Professors: Ricky Foster and Virginia Ferris. The aim of this project was to evaluate different strategies for management of Root Knot Nematode (RKN) on soybean and tomato in Indiana. Seed treatments were evaluated under field and greenhouse conditions, but ...
