Reação de genótipos de pessegueiro a Meloidogyne incognita
… são os gêneros Mesocriconema, Pratylenchus, e Meloidogyne, conhecido como nematoide-das-galhas, considerado um dos principais problemas para a cultura no Brasil. O objetivo deste trabalho foi avaliar os genótipos de pessegueiro desenvolvidos pelo Programa de Melhoramento Genético de pessegueiro …

Patogenicidade de populações de Meloidogyne incognita, provenientes de Minas Gerais e São Paulo, ao cafeeiro
As quatro raças de Meloidogyne incognita apesar de presentes em outras culturas e plantas daninhas em Minas Gerais, não são detectadas em cafeeiros no Estado, diferentemente do que ocorre em outras áreas produtoras de café no Brasil, onde esta espécie de nematóide das galhas é um dos principais …

Uso de resíduos vegetais para o controle dos nematóides das galhas Meloidogyne javanica (Treub) e Meloidogyne incognita (Kofoid e White)
Os nematóides das galhas, gênero Meloidogyne, são considerados os de maior importância agrícola, pois parasitam mais de 2000 espécies de plantas, causando perdas significativas. O controle desses nematóides é muito difícil devido à escassez de cultivares resistentes, dificuldade da adoção de …

Investigating the role of neuropeptides in plant parasitic nematodes
… which induce aberrant behaviours in Meloidogyne incognita and Globodera pallida conferring resistance to tomato seedlings. This thesis demonstrated Bacillus subtilis signal peptide optimisation using NLP-15b. NLP-15b showed a potent effect during initial studies conferring host …

An investigation into the potential of crude and partially separated material of selected non–crop plant species as control agents of root–knot nematodes (Meloidogyne incognita) in tomato
… effect on the plant-parasitic nematode (PPN) (Meloidogyne incognita) on tomato. Subsequent assessments in microplots and in the field supported the glasshouse results in terms of suppression of root-knot nematode numbers with crudely milled soil amendments of C. cactiformis, M. angolensis and …

The development of gene silencing strategies for plant parasitic nematodes
… Globodera pallida and the root knot nematode Meloidogyne incognita. Much of the work contributing to this project has advanced our understanding of RNAi in these nematodes, and may also have broader implications for other parasitic nematode species. Although RNAi has been used widely to probe …

Intercropping with resistant cultivars reduces early blight and root knot disease on susceptible cultivars of tomato (Lycopersicon esculentum)
… in the spread of the parasitic nematode Meloidogyne incognita to 'Brandywine' when interplanted with root knot disease resistant cultivar 'Celebrity' was observed in the greenhouse. Results suggest that intercropping with resistant cultivars is effective in reducing diseases on …

Reproduction of a root-knot nematode population on flue-cured tobacco homozygous for Rk1 and/or Rk2 resistance genes and the effect of soil temperature on resistance gene efficacy
… gene, providing resistance to races 1 and 3 of Meloidogyne incognita and race 1 of M. arenaria. This initiated a shift in root-knot populations to other species and races, creating a need for resistance to those populations. Numerous cultivars possess a second resistance gene, Rk2. Greenhouse …

Análise proteômica de raízes de soja em resposta à inoculação com nematoides de galha
… resposta à inoculação com nematoides de galha (Meloidogyne javanica e Meloidogyne incognita). Foram avaliadas amostras de raízes de soja, da cultivar resistente Conquista, coletadas 12, 24 e 48 horas após a inoculação tendo como controle raízes de plantas não inoculadas. As proteínas foram …

Nature of the root-knot resistance introduced into Lycopersicon esculentum by interspecific crosses with Lycopersicon peruvianum
… resistant and susceptible lines of tomato to Meloidogyne incognita, M. incognita var. acrita, M. javanica, M. hapla and M. arenaria and to determine the mode of inheritance of nematode resistance and the number of genetic factors controlling resistance to the root-knot nematodes. Four …

The Effects of European corn borer on whole-plant yieldand root knot nematode fitness in corn
… and belowground herbivory by root knot nematode, Meloidogyne incognita Chitwood (Tylenchida: Heteroderidae), in corn. Two experiments were conducted to measure belowground herbivory by M. incognita in juvenile penetrations and eggs/root system. In the first experiment, the main effects interaction …

Developmental biology of heterodera glycines (soybean cyst nematode) and other plant - parasitic nematodes
… site, sedentary nematodes females (H. glycines, Meloidogyne incognita, and Rotylenchulus reniformis) become immobile. Interestingly, loss of mobility after infection is reversed in adult (H. glycines and Meloidogyne incognita) males while females never regain mobility. In C. elegans, contraction …
