Resistance to root-knot nematode in tomato roots expressing a nematicidal Bacillus thuringiensis crystal protein.
Our laboratory has demonstrated previously that Bacillus thuringiensis (Bt) crystal (Cry) proteins present in the Cry5 and Cry6 subclades intoxicate free-living nematodes. In this study, we tested whether the expression of nematicidal Cry6A in transgenic plants provided protection against plant-parasitic nematodes. As bacterial codon usage is incompatible with expression in plants, two differen...
متن کاملInterrelationships between Ethylene Production, Gall Formation, and Root-knot Nematode Development in Tomato Plants Infected with Meloidogyne javanica.
Ethylene production was determined in excised tomato (Lycopersicon esculentum) root cultures of Meloidogyne javanica susceptible and resistant cultivars infected with M. javanica. Uninfected cultivars produced very low amounts of ethylene. Relatively high amounts of ethylene were produced by the infected susceptible cultivars. Peak production of 1.6 n moles * g root(1) * h(1) occurred between 9...
متن کاملEffect of Oryzalin and 1,1-Dimethylpiperidinium Chloride on Cotton and Tomato Roots Infected with the Root-knot Nematode, Meloidogyne incognita.
Oryzalin (3,5-dinitro-N4,N4-dipropyl-sulfanilamide) and BAS 083 (l,l-dimethylpiperdinium chloride) reduced root-knot infection in tomato roots when respectively applied as a soil drench at 20 ppm and 10,000 ppm. Oryzalin reduced knot counts with various intervals between treatment and inoculation. BAS 083 reduced knot counts only when applied before inoculation. Oryzalin was shown not to be a c...
متن کاملGreen Nanoparticles Engineering on Root-knot Nematode Infecting Eggplant plants and Their Effect on Plant DNA Modification
Background: Root-knot nematodes are known to cause significant damage to eggplants. New approaches by green silver nanoparticles (GSN) are used to control plant-parasitic nematode to avoid chemical nematicide hazards.Objectives: Analyses of the incorporation of different concentrations of nanoparticles on two different algae (Ulva lactuca and Turbinaria turbinata) were carried out. Fureth...
متن کاملThe Nematicidal Effect of Camellia Seed Cake on Root-Knot Nematode Meloidogyne javanica of Banana
Suppression of root-knot nematodes is crucially important for maintaining the worldwide development of the banana industry. Growing concerns about human and environmental safety have led to the withdrawal of commonly used nematicides and soil fumigants, thus motivating the development of alternative nematode management strategies. In this study, Meloidogyne javanica was isolated, and the nemati...
