The seed of Vigna angularis has long been cultivated as a food or a folk medicine in East Asia. Genistein (4',5,7-trihydroxyisoflavone), a dietary phytoestrogen present in this plant, has been known to possess various biological properties. In this study, we investigated the possible lifespan-extending effects of genistein using Caenorhabditis elegans model system. We found that the lifespan of...
A summer-planted crop of alyceelover significantly (P < 0.05) increased the soil abundance of Meloidogyne arenaria race 2 juveniles by 3.7-fold when measured in the following spring. Maize, sorghum, and soybean had no significant effects on residual nematode numbers over the same period. Summer plantings of aeschynomene, cotton, hairy indigo, tespedeza, millet, peanut, and sorghum-sudangrass we...
Activation of the mucosal immune system of the gastrointestinal tract in nematode infection results in altered intestinal physiology, which includes changes in intestinal motility and mucus production. These changes are considered to be under direct immunological control rather than a non-specific consequence of the inflammatory reaction to the infective agent. However, little is known about th...
beet cyst nematode (heterodera schachtii schmidt). spreads extensively in different regions of sugar beet cultivation, and therefore many efforts are accomplished to prevent decrease of sugar and root yield caused by the disease. the most appropriate control method of this disease is improvement of resistant varieties. wild species of procumbentes in beta are very important because they contain...
a computer software was designed to facilitate identification of nematode species. the first section of the computer program was prepared to identify the species of the genus criconemoides. nemidsoft can be easily installed on personal computers with a minimal requirements. the software can be edited by users and developed and generalized to other genera of the nematodes. by having the morpholo...
During taxonomic investigations of nematodes that parasitize millipedes, we reviewed the literature on the nematode genus Robertia Travassos & Kloss, 1961. This literature search also revealed the existence of two other identical genusgroup names for taxa in Chordata and Arthropoda: Robertia Boonstra, 1948 (extinct Permian non-mammalian synapsid) and Robertia Saaristo, 2006 (theridiid spider fr...
Meloidogyne incognita, Hoplolaintus galeatus, and North Carolina and Georgia populations of Belonolaimus longicaudatus were introduced singly and in various combinations with Fusarium oxysporum f. sp. vasinfectum on wilt-susceptible 'Rowden' cotton. Of all the nematodes, the combination of the N. C. population of B. longicaudatus with Fusarium promoted greatest wilt development. H. galeatus had...
Nematode-trapping fungi are "carnivorous" and attack their hosts using specialized trapping devices. The morphological development of these traps is the key indicator of their switch from saprophytic to predacious lifestyles. Here, the genome of the nematode-trapping fungus Arthrobotrys oligospora Fres. (ATCC24927) was reported. The genome contains 40.07 Mb assembled sequence with 11,479 predic...
In this study, we sequenced mt Cox 1 gene sequences of five nematode spp. that were infective to arthropod, Gryllotalpa africana. The nematode belongs to Thelastomatoidea, a group of pinworms that parasitizes only invertebrates. Currently, in India spp. of this group are distinguished mainly on the basis of morphological characters that present possible confusions. Therefore, we identified the ...
Abamectin is nematicidal to Meloidogyne incognita and Rotylenchulus reniformis, but the duration and length of cotton taproot protection from nematode infection by abamectin-treated seed is unknown. Based on the position of initial root-gall formation along the developing taproot from 21 to 35 d after planting, infection by M. incognita was reduced by abamectin seed treatment. Penetration of de...
