Cowpea (Vigna unguiculata L. Walp) is an ancient crop widely known as Lobia, Vegetable crop, Black-eyed peas. used pulse, fodder, vegetable, and green manure crop. It to suffer from many diseases pests. Nematodes cause a severe damage cowpea production leading economic losses. Among the nematodes, root-knot nematodes (Meloidogyne spp.) Farmyard manure, spent mushroom compost, leaf waste of mari...

The tomato Mi-1.2 gene confers resistance against both root-knot nematodes and the potato aphid. Plants are resistant to nematodes early in root development. However, plants as old as 4 weeks are susceptible to aphid infestation. We monitored Mi-1.2 expression at the transcriptional level in resistant (Mi/Mi) and susceptible (mi/mi) tomato cultivars by means of RT-PCR. Mi-1.2 transcripts accumu...

Root-knot nematodes represent one of the most important plant pathogens in Pomegranate cultivation regions. By studying structure plant-parasitic community inhabiting rhizosphere fields, it was found that

root-knot nematodes (meloidogyne spp.) are one of the most important plant parasitic nematodes which cause damage to crops. in recent years, using of medicinal plants has been considered to many scientists as effective methods for controlling nematodes. in this study, essential oils of ecalyptus spp., dorema ammoniacum and ferula galbanifula were tested against the root-knot nematode (meloidogy...

Three closely related parthenogenetic species of root-knot nematodes, collectively termed the Meloidogyne incognita-group, are economically significant pathogens of diverse crop species. Remarkably, these asexual root-knot nematodes are capable of acquiring heritable changes in virulence even though they lack sexual reproduction and meiotic recombination. Characterization of a near isogenic pai...

Root-knot nematodes (Meloidogyne spp.) are the most common and destructive plant-parasitic nematode group worldwide and adversely influence both crop quality and yield. In this study, a total of 51 root-knot nematode populations from turfgrasses were tested, of which 44 were from North Carolina, 6 from South Carolina and 1 from Virginia. Molecular characterisation was performed on these samples...

Root-knot nematodes secrete effectors that manipulate their host plant cells so that the nematode can successfully establish feeding sites and complete its lifecycle. The root-knot nematode feeding structures, their "giant cells," undergo extensive cytoskeletal remodeling. Previous cytological studies have shown the cytoplasmic actin within the feeding sites looks diffuse. In an effort to study...

Carrot (Dacus carota var. sativus) is one of the top-ten most economically important vegetable crops produced worldwide, and the root-knot nematodes, Meloidogyne spp., are one of the most important pests in the carrot. In Korea, M. hapla and M. incognita are presumed to be the major root-knot nematodes distributing mostly in open carrot fields and greenhouses, respectively. In our study, curren...

The polyphagous parthenogenetic root-knot nematodes of the genus Meloidogyne are considered to be the most significant nematode pest in sub-tropical and tropical agriculture. Despite the crucial need for correct diagnosis, identification of these pathogens remains problematic. The traditionally used diagnostic strategies, including morphometrics, host-range tests, biochemical and molecular tech...
