25. Transcriptome analysis of resistant soybean roots infected by Meloidogyne javanica
Soybean is an important crop for Brazilian agribusiness. However, many factors can limit its production, especially root-knot nematode infection. Studies on the mechanisms employed by the resistant soybean genotypes to prevent infection by these nematodes are of great interest for breeders. For these reasons, the aim of this work is to characterize the trans

28. Reação de genótipos de feijão-mungo a Meloidogyne javanica e Pratylenchus brachyurus em condições de campo.
RESUMO: Foram avaliados 10 genótipos de feijão-mungo (Vidna radiata L.) quanto à infecção por nematóide-das-galhas, Meloidogyne javanica e por nematóide-das-lesões, Pratylenchus brachyurus na área experimental da Embrapa Cerrados. A população inicial dos nematóides (Pi) no solo, por parcela, foi avaliada antes do plantio (novembro de 1985). Aos 7

29. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion

30. Reprodução e patogenicidade de Meloidogyne javanica no híbrido EC-2-0 de maracujá-azedo.
RESUMO: O nematóide formador de galha das raízes, Meloidogyne javanica (Treub) Chitwood constitui-se ameaça para a cultura do maracujá-azedo, Passiflora edulis f. flavicarpa na Região do Cerrado. O híbrido EC-2-0 (cultivar Marília Sul Brasil x Roxo Australiano) tem grande potencial de produção no Cerrado e maior tolerância às doenças da parte aé

31. Nematicidal activity of leaf extracts from Lantana camara L. against Meloidogyne incognita (kofoid and white) chitwood and its use to manage roots infection of Solanum melongena L.
Various concentrations of aqueous leaf extract of Lantana camara were assessed in vitro conditions against second stage juveniles (J2) of Meloidogyne incognita. The standard concentration 'S' of leaf extract was found to be highly nematostatic, where nematodes were completely paralyzed after 12 h and after 48 h of exposure, 96% of juveniles were killed at sa

32. "Reação de famílias de cana-de-açúcar (Saccharum sp.) em relação a Meloidogyne incognita (Kofoid &White, 1919) Chitwood, 1949" / Reaction of sugarcane families (Saccharum sp.) to Meloidogyne incognita (Kofoid &White, 1919) Chitwood,1949
The sugarcane crop has a special significance to the Brazilian economy that is a leading producing country. This crop is attacked by several pathogens and, amongst them are the nematodes of the genera Meloidogyne, that reduces the sugarcane yield. The use of chemical control, crop rotation, use of antagonistic plants and genetic control by introducing resist

33. RESISTÃNCIA DE CULTIVARES DE FEIJÃO E FEIJÃO-VAGEM AOS NEMATOIDES DAS GALHAS / Resistance of bean and snap bean cultivars to root-knot nematodes.
The objective of this work was to assess the reaction of field and snap bean cultivars to the infestation by Meloidogyne incognita races 1 and 3 and Meloidogyne javanica. Three independent experiments to each species and race of Meloidogyne with four replicates and four plants per plot were conducted. In each block, a plot with the susceptible tomato cultiva

34. Utilização de matéria orgânica no controle de nematóide das galhas em alface sob cultivo protegido
This research was carried out aiming to evaluate the effect of organic manure in the control of root-knot nematodes in lettuce cv. Verônica. Organic cattle and chicken manure were evaluated; they are both used for vegetable production in the region. The experiment was carried out at Estação Experimental de Biologia, University of Brasilia, from July to No

35. Reação de culturas de cobertura utilizadas no sistema de plantio direto ao nematóide das lesões Pratylenchus brachyurus e ao nematóide das galhas, Meloidogyne incognita / Host status of cover crops used in no tillage system to lesion nematode Pratylenchus brachyurus and to root-knot nematode Meloidogyne incognita
Na região dos cerrados, as principais culturas de cobertura utilizadas para a produção de palha no sistema de plantio direto são o milheto (Pennisetum glaucum R. BR.) e as aveias (Avenas spp.). No entanto, a resposta dessas espécies vegetais frente ao nematóide das lesões (Pratylenchus brachyurus) e o das galhas (Meloidogyne incognita) são escassas.

36. Agronomic characteristics and silage production of sweet potato clones / CARACTERÃSTICAS AGRONÃMICAS E PRODUÃÃO DE SILAGEM DE CLONES DE BATATA-DOCE
Two assays were developed to evaluate sweet potato clones to yield, root quality, silage yield and quality and resistance to the root-knot nematode Meloidogyne incognita race 1, in the municipality of Ijaci, Minas Gerais State, Brazil. In the first assay, twenty accessions from a breeding program from the state of Tocantins, Brazil, together with five commer
