The species of the genus Meloidogyne are globally distributed and generally induce formation galls or nodules in roots a wide variety plants, due to this; this nematode is known as "Root knot nematode". affected plants show loss turgidity leaves, chlorosis withering, which leads reduction crop yields. In Ecuador, presence several root has been registered, wild cultivated plants. For diagnosis, ...

The southern root-knot nematode, Meloidogyne incognita, is the most damaging pathogen of cotton in the USA. Host-plant resistance to root-knot nematodes is an effective means of reducing crop losses and reducing nematode population levels in a field. Resistance to plantparasitic nematodes refers to the suppressive effect of the plant on the nematode’s ability to reproduce; tolerance describes t...

Root-knot nematodes (Meloidogyne spp.) are a significant problem in potato (Solanum tuberosum) production. There is no potato cultivar with Meloidogyne resistance, even though resistance genes have been identified in wild potato species and were introgressed into breeding lines. The objectives of this study were to generate stable transgenic potato lines in a cv. Russet Burbank background that ...

the present study is based on the investigation of a soil hyphomyces, paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode meloidogyne javanica on tomato in greenhouse conditions. p. lilacinus, effectively promoted the growth of plants inoculated with m. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

Recent studies reveal an intimate connection between the quantum knot invariant and the “nearly modular form” especially with the half integral weight. In Ref. 8 Lawrence and Zagier studied an asymptotic expansion of the Witten–Reshetikhin–Turaev invariant of the Poincaré homology sphere, and they showed that the invariant can be regarded as the Eichler integral of the modular form of weight 3/...
