Temporal Formation and Immunolocalization of an Endospore Surface Epitope During Pasteuria penetrans Sporogenesis.
The synthesis and localization of an endospore surface epitope associated with the development of Pasteuria penetrans was determined using a monoclonal antibody (MAb) as a probe. Nematodes, uninfected or infected with P. penetrans, were harvested at 12, 16, 24, and 38 days after inoculation (DAI) and then examined to determine the developmental stage of the bacterium. Vegetative growth of P. pe...
متن کاملTransfer and Development of Pasteuria penetrans.
Pasteuria penetrans isolate P-20 has been attributed as the cause of soil suppressiveness to peanut root-knot nematode in Florida. In this study, P. penetrans was transferred from a suppressive site to a new site and established by growing susceptible hosts to the peanut root-knot nematode during both summer and winter seasons. When two soil fumigants, 1,3-dichloropropene (1,3-D) and chloropicr...
متن کاملMinimal Growth Temperature of Pasteuria penetrans.
Pasteuria penetrans is an obligate, mycelial, and endospore-forming bacterial parasite of Meloidogyne spp. with promise for the management of root-knot nematodes. Our objective was to use regression analysis of developmental time (days) to various temperatures to determine the minimal temperature for growth and development of P. penetrans in Meloidogyne spp. The data set for regression originat...
متن کاملGenetic and immunological comparison of the cladoceran parasite Pasteuria ramosa with the nematode parasite Pasteuria penetrans.
Pasteuria penetrans, an obligate endospore-forming parasite of Meloidogyne spp. (root knot nematodes), has been identified as a promising agent for biocontrol of these destructive agricultural crop pests. Pasteuria ramosa, an obligate parasite of water fleas (Daphnia spp.), has been shown to modulate cladoceran populations in natural ecosystems. Selected sporulation genes and an epitope associa...
متن کاملReview of Pasteuria penetrans: Biology, Ecology, and Biological Control Potential.
Pasteuria penetrans is a mycelial, endospore-forming, bacterial parasite that has shown great potential as a biological control agent of root-knot nematodes. Considerable progress has been made during the last 10 years in understanding its biology and importance as an agent capable of effectively suppressing root-knot nematodes in field soil. The objective of this review is to summarize the cur...
