Secreted proteins coded by parasitism genes expressed in esophageal gland cells mediate infection and parasitism of plants by root-knot nematodes. An essential parasitism gene, designated as 16D10, encodes a conserved root-knot nematode secretory peptide that stimulates root growth and functions as a ligand for a plant transcription factor. Plants were engineered to silence this parasitism gene...

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...

The potential of 13 Paecilomyces lilacinus isolates from various geographic regions as biocontrol agents against Meloidogyne incognita, the effects of temperature on their growth, and the characterization of the impact of soil temperature on their efficacy for controlling this nematode were investigated. Maximum fungal growth, as determined by dry weight of the mycelium, occurred from 24 to 30 ...

Root-knot nematode, Meloidogyne incognita, is one of the main problems in vegetable-growing regions, decreasing yield quality and quantity worldwide. Root-knot nematode management tactics mostly involve chemical control which is a threat to the environment, consequences to human health. Biological control of nematodes is considered to be one of the best alternatives to the chemical control. In ...

Restrictions on the use of conventional nematicides have increased the need for new methods of managing plant-parasitic nematodes. Consequently, nematode-antagonistic microbes, and active compounds produced by such organisms, are being explored as potential additions to management practices. Programs in this area at the USDA Agricultural Research Service investigate applied biocontrol agents, n...

systemic induction of peroxidase and polyphenoloxidase in tomato roots and stem followed by application of split root system method was investigated. root system of tomato seedling in the sixth growth stage were divided in two equal sections after washing and replanted in two adjacent pots and then inoculated with nematode and fungus as fallowing treatments. the second treatment was inoculation...

root-knot nematodes, meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. the most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. in the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. in the supplementary studie...
