The teneurin C-terminal domain possesses nuclease activity and is apoptogenic. [PDF]

open access: yes, 2018
Teneurins are type 2 transmembrane proteins expressed by developing neurons during periods of synaptogenesis and apoptosis. Neurons expressing teneurin-1 synapse with other teneurin-1-expressing neurons, and neurons expressing teneurin-2 synapse with ...

Cry1 holotype toxins of Bacillus thuringiensis

open access: yesJournal of Pharmacy Research, 2013
Abstract Bacillus thuringiensis is a gram-positive bacterium which produces insecticidal parasporal crystal proteins (ICPs) during stationary phase of its growth cycle. Cry1 halotype toxins form the largest class of insecticidal crystal proteins which are produced as protoxins (130 kDa).

Mode of Action and Specificity of Bacillus thuringiensis Toxins in the Control of Caterpillars and Stink Bugs in Soybean Culture

open access: yesISRN Microbiology, 2014
The bacterium Bacillus thuringiensis (Bt) produces delta-endotoxins that possess toxic properties and can be used as biopesticides, as well as a source of genes for the construction of transgenic plants resistant to insects.

Bt Toxin Modification for Enhanced Efficacy

open access: yesToxins, 2014
Insect-specific toxins derived from Bacillus thuringiensis (Bt) provide a valuable resource for pest suppression. Here we review the different strategies that have been employed to enhance toxicity against specific target species including those that ...

A bacterial binary toxin system that kills both insects and aquatic crustaceans: Photorhabdus insect-related toxins A and B.

open access: yesPLoS Pathogens, 2023
Photorhabdus insect-related toxins A and B (PirA and PirB) were first recognized as insecticidal toxins from Photorhabdus luminescens. However, subsequent studies showed that their homologs from Vibrio parahaemolyticus also play critical roles in the ...

Histopathological effects of cypermethrin and Bacillus thuringiensis var. israelensis on midgut of Chironomus calligraphus larvae (Diptera: Chironomidae) [PDF]

open access: yes, 2018
Pesticides are extensively used for the control of agricultural pests and disease vectors, but they also affect non-target organisms. Cypermethrin (CYP) is a synthetic pyrethroid used worldwide. Otherwise, bioinsecticides like Bacillus thuringiensis var.

A Pilot Study for the Characterization of Bacillus spp. and Analysis of Possible B. thuringiensis/Strongyloides stercoralis Correlation

open access: yesMicroorganisms
Differentiating between Bacillus species is relevant in human medicine. Bacillus thuringiensis toxins might be effective against Strongyloides stercoralis, a nematode causing relevant human morbidity. Our first objective was to evaluate genomic and MALDI-

Microorganisms and their byproducts, nematodes, oils and particle films have important agricultural uses

open access: yesCalifornia Agriculture, 2005
The insect and mite control potential of natural and biological toxins has been recognized for several centuries. Bacteria, viruses, protozoa and fungi are the primary groups of microorganisms known to reduce insect populations; they often occur ...
