Characterization of the putative antigenic determinants on Pasteuria endospore surface using Bacillus thuringiensis as a comparative tool
Srivastava, Arohi; Mohan, Sharad; Davies, Keith (2016-08-28)Biological control agents are emerging as potential environmentally benign means of combating phytonematodes across the world. Some species of Pasteuria are endospore forming bacterial hyperparasites of nematodes associated ... -
Evidence for diversifying selection of genetic regions of encoding putative collagen-like host-adhesive fibers in Pasteuria penetrans
Srivastava, Arohi; Mohan, Sharad; Mauchline, Tim H.; Davies, Keith (2019-01-01)Pasteuria spp. belong to a group of genetically diverse endospore-forming bacteria (phylum: Firmicutes) that are known to parasitize plant-parasitic nematodes and water fleas (Daphnia spp.). Collagen-like fibres form the ... -
Exploiting genomics to improve the biological control potential of Pasteuria spp., an organisms with potential to control plant-parasitic nematodes
Srivastava, Arohi; Hall, Avice; Graeme-Cook, Kate; Davies, Keith (2014-11)The Pasteuria group of Gram positive bacteria are invertebrate parasites with the potential to be developed into biological control agents of plant-parasitic nematodes. A key step in the infection process is the attachment ... -
Exploring Bacillus thuringiensis as a model for endospore adhesion and its potential to investigate adhesins in Pasteuria penetrans
Srivastava, Arohi; Mohan, Sharad; Davies, Keith (2022-06-01)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. ... -
Exploring the endospore coat of Pasteuria penetrans, the bacterial hyperparasite of plant-parasitic nematodes, using Bacillus spp.
Srivastava, Arohi; Mauchline, Tim H.; Davies, Keith (2016-04-19)Pasteuria penetrans, previously named as Bacillus penetrans, belong to a group of Gram positive endospore forming bacteria (phylum: Firmicutes; family: Pasteuriaceae) that are hyperparasites of plant-parasitic nematodes. ... -
Exploring the mechanisms of host-specificity of a hyperparasitic bacterium (Pasteuria spp.) with potential to control tropical root-knot nematodes (Meloidogyne spp.): insights from Caenorhabditis elegans
Davies, Keith; Mohan, Sharad; Phani, Victor; Srivastava, Arohi (2023-12-20)Plant-parasitic nematodes are important economic pests of a range of tropical crops. Strategies for managing these pests have relied on a range of approaches, including crop rotation, the utilization of genetic resistance, ... -
The importance of being adhesive
Davies, Keith; Srivastava, Arohi (2019-06-19)Phytonematodes cause annual crop losses of $100 billion per year. Pasteuria penetrans is a bacterium that has potential to be developed into a biological control agent as an alternative to nematicides. This poster is an ... -
The Molecular Basis of Pasteuria-nematode Interactions Using Closely Related Bacillus spp.
Srivastava, Arohi (2017-07-24)Phytonematodes are known to cause substantial losses in crop yields across the world. Since the middle of the last century, these pests have been adequately controlled by chemical nematicides. However, due to increasing ... -
Understanding nematode suppressive soils: molecular interactions between Pasteuria endospores and the nematode surface coat
Davies, Keith; Srivastava, Arohi; Kumar, Kiran; Mohan, Sharad (Association of Applied Biologists, 2015-09-07)The knowledge that the plant-parasitic nematode hyperparasite Pasteuria penetrans is important in nematode suppressive soils has long been recognised. The ability to mass produce this organism in vitro circumvents one of ...
