Plant parasitic nematodes associated with leatherleaf fern.
Seven species of plant parasitic nematodes were found to be associated with leatherleaf fern (Rumohra adiantiformis) in central Florida. Of these, Pratylenchus penetrans, Tylenchorhynchus claytoni, and Criconemoides curvatum were commonly encountered. Nematode communities generally included two or three species of plant parasitic nematodes, with greatest diversity in nematode species occurring ...
متن کاملsiRNAs Trigger Efficient Silencing of a Parasitism Gene in Plant Parasitic Root-Knot Nematodes
Expanding genomic data on plant pathogens open new perspectives for the development of specific and environment friendly pest management strategies based on the inhibition of parasitism genes that are essential for the success of infection. Identifying such genes relies on accurate reverse genetics tools and the screening of pathogen knock-down phenotypes. Root-knot nematodes are major cosmopol...
متن کاملThe dual effects of root-cap exudates on nematodes: from quiescence in plant-parasitic nematodes to frenzy in entomopathogenic nematodes
To defend themselves against herbivores and pathogens, plants produce numerous secondary metabolites, either constitutively or de novo in response to attacks. An intriguing constitutive example is the exudate produced by certain root-cap cells that can induce a state of reversible quiescence in plant-parasitic nematodes, thereby providing protection against these antagonists. The effect of such...
متن کاملParasitic plant responses to host plant signals: a model for subterranean plant-plant interactions.
The ability of plants to fulfill nutritional needs by parasitizing neighboring plants has originated several times in angiosperm evolution. Molecular tools are now being exploited to investigate the evolutionary origins of plant parasitism and to dissect the genetic mechanisms governing parasitic plant-host plant interactions. Investigating the nature of signal exchanges between parasitic plant...
متن کاملPlant-parasitic nematodes and fungi associated with root rot of peas on prince edward island.
Eight commercial pea fields on Prince Edward Island were sampled in June and July over a 2-year period (1986-87) to determine soil population densities and the incidence of nematodes and fungi associated with root rot of peas. Root lesion nematodes (Pratylenchus spp.) were the dominant endoparasitic nematodes recovered from roots and soil. Low populations of the northern root-knot nematode (Mel...
