Root-knot nematode disease occurs frequently due to continuous monocropping and excessive water nitrogen input. The degree gall index are often used evaluate the damage of root-knot disease. However, weak correlation between these two indicators tobacco leaf dry weight has been reported. objective this study was verify whether use density (RKD)—the number per unit root or volume—as a new indica...

Parasitism genes expressed in the esophageal gland cells of root-knot nematodes encode proteins that are secreted into host root cells to transform the recipient cells into enlarged multinucleate feeding cells called giant-cells. Expression of a root-knot nematode parasitism gene which encodes a novel 13-amino-acid secretory peptide in plant tissues stimulated root growth. Two SCARECROW-like tr...

With the understanding of nematode-plant interactions at the molecular level, new avenues for engineering resistance have opened up, with RNA interference being one of them. Induction of RNAi by delivering double-stranded RNA (dsRNA) has been very successful in the model non-parasitic nematode, Caenorhabditis elegans, while in plant nematodes, dsRNA delivery has been accomplished by soaking nem...

Abstract Background Root-knot nematodes ( Meloidogyne spp.) are among the most important plant pathogens. Biological control is one of safety and effective methods for these nematodes. The aim present study was isolation identification endophytic bacteria from tomato fields in some areas Iran order to evaluate their biocontrol potential against root-knot nematode. In study, population collected...

Brassicas have been used frequently for biofumigation, a pest-management strategy based on the release of biocidal volatiles during decomposition of soil-incorporated tissue. However, the role of such volatiles in control of plant-parasitic nematodes is unclear. The goal of this study was to determine the direct localized and indirect volatile effects of amending soil with broccoli tissue on ro...

First Report of Root-Knot Nematode Meloidogyne hapla (Chitwood, 1949) (Nematoda: Meloidogynidae) on Petroselinum crispum (Mill.) Nym. ex A.W. Hill) in Turkey
 ABSTRACT
 Parsley (Petroselinum crispum), a vegetable whose leaves are consumed, is taxonomomically positioned the Apiaceae family. The origin parsley known as Mediterranean Region. In Turkey, it cultivated extensively and Aegea...

In this study conducted in 2020, three concentrations (1, 5 and 10 µM) of 24-epibrassinolide were applied to seedlings Lycopersicon esculentum Mill. (Solanales: Solanaceae) cv. H2274, which is susceptible root-knot nematodes, by immersion, spray irrigation, its effects against nematode Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949 (Tylenchida: Meloidogynidae) investigated. One-tho...
