Rapid change in host specificity in a field population of the biological control organism Pasteuria penetrans [PDF]

Evolutionary Applications, 2019
In biological control, populations of both the biological control agent and the pest have the potential to evolve and even to coevolve. This feature marks the most powerful and unpredictable aspect of biological control strategies.

A diverse parasite pool can improve effectiveness of biological control constrained by genotype‐by‐genotype interactions [PDF]

Evolutionary Applications, 2022
The outcomes of biological control programs can be highly variable, with natural enemies often failing to establish or spread in pest populations. This variability has posed a major obstacle in use of the bacterial parasite Pasteuria penetrans for ...

Maternal Stress Reduces the Susceptibility of Root-Knot Nematodes to Pasteuria Penetrans [PDF]

Journal of Nematology, 2019
Pasteuria penetrans is an obligate parasite of root-knot nematodes (Meloidogyne spp.). Endospores of P. penetrans attach to the cuticle of second-stage juveniles (J2) and complete their life cycle within the nematode female body. Infected females will be

Do biological control agents adapt to local pest genotypes? A multiyear test across geographic scales [PDF]

Evolutionary Applications
Parasite local adaptation has been a major focus of (co)evolutionary research on host–parasite interactions. Studies of wild host–parasite systems frequently find that parasites paired with local, sympatric host genotypes perform better than parasites ...

A transcriptomic snapshot of early molecular communication between Pasteuria penetrans and Meloidogyne incognita [PDF]

BMC Genomics, 2018
Background Southern root-knot nematode Meloidogyne incognita (Kofoid and White, 1919), Chitwood, 1949 is a key pest of agricultural crops. Pasteuria penetrans is a hyperparasitic bacterium capable of suppressing the nematode reproduction, and represents ...

Meloidogyne incognita Fatty Acid- and Retinol- Binding Protein (Mi-FAR-1) Affects Nematode Infection of Plant Roots and the Attachment of Pasteuria penetrans Endospores [PDF]

Frontiers in Microbiology, 2017
Root-knot nematode (RKN) Meloidogyne incognita is an economically important pest of crops. Pasteuria penetrans, is a nematode hyperparasitic bacterium capable of suppressing the reproduction of RKN and thereby useful for its management.

ENDOSYMBIONT MICROBIOTA OF Meloidogyne javanica ADULT FEMALE INFECTED BY Pasteuria penetrans

Tropical and Subtropical Agroecosystems, 2022
Background: Pasteuria penetrans is a nonculturable bacterium that obligately parasitizes several species of phytopathogenic nematodes. Unknown endogenous female, plant or microbial reproductive factors are indispensable for multiplication and endospore ...

Phylogenetic analysis of Pasteuria penetrans by use of multiple genetic loci. [PDF]

J Bacteriol, 2005
ABSTRACT Pasteuria penetrans is a gram-positive, endospore-forming eubacterium that apparently is a member of the Bacillus-Clostridium clade. It is an obligate parasite of root knot nematodes ( Meloidogyne spp.) and preferentially grows on the developing ovaries ...
