The amino- and carboxyl-terminal fragments of the Bacillus thuringensis Cyt1Aa toxin have differential roles on toxin oligomerization and pore formation
The Cyt toxins produced by the bacteria Bacillus thuringiensis show insecticidal activity against some insects, mainly dipteran larvae, being able to kill mosquitoes and black flies. However, they also possess a general ... -
Bacillus thuringiensis Cyt proteins as enablers of activity of Cry and Tpp toxins against Aedes albopictus
Aedes albopictus is a species of mosquito, originally from Southeast Asia, that belongs to the Culicidae family and the Dipteran insect order. The distribution of this vector has rapidly changed over the past decade, making ... -
Bacillus thuringiensis toxins: an overview of their biocidal activity
Bacillus thuringiensis (Bt) is a Gram positive, spore-forming bacterium that synthesizes parasporal crystalline inclusions containing Cry and Cyt proteins, some of which are toxic against a wide range of insect orders, ... -
Binding of Bacillus thuringiensis subsp. israelensis Cry4Ba to Cyt1Aa has an important role in synergism
Bacillus thuringiensis subsp. israelensis (Bti) produces at least four different crystal proteins that are specifically toxic to different mosquito species and that belong to two non-related family of toxins, Cry and ... -
Domain shuffling between Vip3Aa and Vip3Ca: chimera stability and insecticidal activity against European, American, African, and Asian pests
The bacterium Bacillus thuringiensis produces insecticidal Vip3 proteins during the vegetative growth phase with activity against several lepidopteran pests. To date, three different Vip3 protein families have been identified ... -
Draft genome sequence of Bacillus thuringiensis serovar tolworthi strain Na205-3, an isolate toxic for Helicoverpa armigera
We report here the complete annotated 6,510,053-bp draft genome sequence of Bacillus thuringiensis serovar tolworthi strain Na205-3, which is toxic for Helicoverpa armigera. This strain potentially contains nine insecticidal ... -
Draft genome sequences of two bacillus thuringiensis strains and characterization of a putative 41.9-kDa insecticidal toxin
In this work, we report the genome sequencing of two Bacillus thuringiensis strains using Illumina next-generation sequencing technology (NGS). Strain Hu4-2, toxic to many lepidopteran pest species and to some mosquitoes, ... -
Molecular and insecticidal characterization of a novel cry-related protein from bacillus thuringiensis toxic against Myzus persicae
This study describes the insecticidal activity of a novel Bacillus thuringiensis Cry-related protein with a deduced 799 amino acid sequence (~89 kDa) and ~19% pairwise identity to the 95-kDa-aphidicidal protein (sequence ... -
Multifunctional properties of a bacillus thuringiensis strain (BST-122): beyond the parasporal crystal
Chemical products still represent the most common form of controlling crop pests and diseases. However, their extensive use has led to the selection of resistances. This makes the finding of new solutions paramount to ... -
Potential of Cry10Aa and Cyt2Ba, two minority δ-endotoxins produced by Bacillus thuringiensis ser. israelensis, for the control of Aedes aegypti larvae
Bacillus thuringiensis ser. israelensis (Bti) has been widely used as microbial larvicide for the control of many species of mosquitoes and blackflies. The larvicidal activity of Bti resides in Cry and Cyt δ-endotoxins ... -
Potential of the Bacillus thuringiensis toxin reservoir for the control of Lobesia botrana (Lepidoptera: tortricidae), a major pest of grape plants
The potential of Bacillus thuringiensis Cry proteins to control the grape pest Lobesia botrana was explored by testing first-instar larvae with Cry proteins belonging to the Cry1, Cry2, and Cry9 groups selected for ... -
A strain of Bacillus thuringiensis containing a novel cry7Aa2 gene that is toxic to Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae)
The genome of the Bacillus thuringiensis BM311.1 strain was sequenced and assembled in 359 contigs containing a total of 6,390,221 bp. The plasmidic ORF of a putative cry gene from this strain was identified as a potential ... -
Use of Bacillus thuringiensis toxins for control of the cotton pest earias insulana (Boisd.) (Lepidoptera: Noctuidae)
Thirteen of the most common lepidopteran-specific Cry proteins of Bacillus thuringiensis have been tested for their efficacy against newly hatched larvae of two populations of the spiny bollworm, Earias insulana. At a ... -
Vip3C, a novel class of vegetative insecticidal proteins from Bacillus thuringiensis
Three vip3 genes were identified in two Bacillus thuringiensis Spanish collections. Sequence analysis revealed a novel Vip3 protein class (Vip3C). Preliminary bioassays of larvae from 10 different lepidopteran species ...
