Detection of Pasteuria penetrans infection in Meloidogyne arenaria race 1 in planta by polymerase chain reaction.
We report on the development of a PCR-based assay to detect Pasteuria penetrans infection of Meloidogyne arenaria in planta using specific primers for recently sequenced sigE, spoIIAB and atpF genes of P. penetrans biotype P20. Amplification of these genes in crude DNA extracts of ground tomato root galls using real-time kinetic PCR distinguished infected from uninfected M. arenaria race 1 by a...
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 کاملPopulation dynamics of Meloidogyne arenaria and Pasteuria penetrans in a long-term crop rotation study.
The endospore-forming bacterium Pasteuria penetrans is an obligate parasite of root-knot nematodes (Meloidogyne spp.). The primary objective of this study was to determine the effect of crop sequence on abundance of P. penetrans. The experiment was conducted from 2000 to 2008 at a field site naturally infested with both the bacterium and its host Meloidogyne arenaria and included the following ...
متن کاملPasteuria penetrans for Control of Meloidogyne incognita on Tomato and Cucumber, and M. arenaria on Snapdragon.
Meloidogyne incognita and Meloidogyne arenaria are important parasitic nematodes of vegetable and ornamental crops. Microplot and greenhouse experiments were conducted to test commercial formulations of the biocontrol agent Pasteuria penetrans for control of M. incognita on tomato and cucumber and M. arenaria on snapdragon. Three methods of application for P. penetrans were assessed including s...
متن کاملEffect of organic amendment on organic metabolites in root knot nematode (Meloidogyne Incognita) infested spinach
The Nematodes are roundworms that are found in every environment of the earth. While some species are harmful parasites, others play a vital role in nutrient cycle and medical research. Nematode infestation in the fields is poly-specific; however, depending on the agro-climatic conditions, one or two species are dominant over the rest. The present studies attempts to observe and control the roo...
