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 ...

Temperature Alters Specificity in a Host–Parasite Interaction [PDF]
Ecology and EvolutionThe Red Queen Hypothesis proposes that genetic variation is maintained in populations through antagonistic coevolution of hosts and parasites. A major assumption of the Red Queen Hypothesis is tight genetic specificity for infection. However, it has been

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

Exploring Bacillus thuringiensis as a model for endospore adhesion and its potential to investigate adhesins in Pasteuria penetrans. [PDF]
J Appl Microbiol, 2022 Abstract Aims Phytonematodes are a constraint on crop production and have been controlled using nematicides; these are highly toxic and legislation in Europe and elsewhere is prohibiting their use and alternatives are being sought. Pasteuria penetrans is a hyperparasitic bacterium that form endospores and have potential to control root‐knot nematodes ...

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

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.

Pre-Crop Choice Shapes Nematode-Attached Bacterial Communities Associated With Reduced Pratylenchus penetrans Invasion of Barley Roots. [PDF]
Environ MicrobiolPlant species vary in how they shape nematode‐suppressive soil microbiomes, and these legacies influence the subsequent crop. Suppressive microbiomes contain specific bacterial taxa that attach to the nematode cuticle, leading to reduced nematode invasion into the root system of the host.

Master of Puppets: How Microbiota Drive the Nematoda Ecology and Evolution? [PDF]
Ecol EvolThe nematode microbiota can influence life‐history traits, thereby shaping the species' ecology and evolutionary trajectories. ABSTRACT In recent decades, the microbiota has emerged as a key driver of biological functions in metazoans, and nematodes are no exception.
