Novel Bacillus thuringiensis Binary Insecticidal Crystal Proteins Active on Western Corn Rootworm, Diabrotica virgifera virgifera LeConte
ABSTRACT A new family of insecticidal crystal proteins was discovered by screening sporulated Bacillus thuringiensis cultures for oral activity against western corn rootworm (WCR) larvae. B.Expand
Insecticidal proteins from Bacillus thuringiensis protect corn from corn rootworms
Field tests of corn co-expressing two new delta-endotoxins from Bacillus thuringiensis (Bt) have demonstrated protection from root damage by western corn rootworm (Diabrotica virgifera virgiferaExpand
Nucleotide sequence and transcriptional analysis of the redD locus of Streptomyces coelicolor A3(2).
Previous genetic evidence suggested that the redD gene product might be involved in the regulation of undecylprodigiosin (Red) biosynthesis in Streptomyces coelicolor. The redD+ gene was subcloned onExpand
Mechanism and DNA-based detection of field-evolved resistance to transgenic Bt corn in fall armyworm (Spodoptera frugiperda)
Evolution of resistance threatens sustainability of transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt). The fall armyworm (Spodoptera frugiperda) is aExpand
Bacillus thuringiensis Cry34Ab1/Cry35Ab1 Interactions with Western Corn Rootworm Midgut Membrane Binding Sites
Background Bacillus thuringiensis (Bt) Cry34Ab1/Cry35Ab1 are binary insecticidal proteins that are co-expressed in transgenic corn hybrids for control of western corn rootworm, Diabrotica virgiferaExpand
Characterization of Cry34/Cry35 Binary Insecticidal Proteins from Diverse Bacillus thuringiensis Strain Collections
ABSTRACT Bacillus thuringiensis crystal proteins of the Cry34 and Cry35 classes function as binary toxins showing activity on the western corn rootworm, Diabrotica virgifera virgifera LeConte. WeExpand
Reduced stability and intracellular transport of dsRNA contribute to poor RNAi response in lepidopteran insects
ABSTRACT RNA interference (RNAi) has become a widely used reverse genetic tool to study gene function in eukaryotic organisms and is being developed as a technology for insect pest management. TheExpand
Binary Insecticidal Crystal Protein from Bacillus thuringiensis, Strain PS149B1: Effects of Individual Protein Components and Mixtures in Laboratory Bioassays
Abstract A family of novel binary insecticidal crystal proteins, with activity against western corn rootworm, Diabrotica virgifera virgifera LeConte, was identified from Bacillus thuringiensisExpand
Functional characterization of Vip3Ab1 and Vip3Bc1: Two novel insecticidal proteins with differential activity against lepidopteran pests
In this work, we characterized 2 novel insecticidal proteins; Vip3Ab1 and Vip3Bc1. These proteins display unique insecticidal spectra and have differential rates of processing by lepidopteranExpand
Long dsRNA but not siRNA initiates RNAi in western corn rootworm larvae and adults
Transgenic maize plants expressing dsRNA targeting western corn rootworm (WCR, Diabrotica virgifera virgifera LeConte) v‐ATPase subunit C mRNA for RNAi provided significant root protection from WCRExpand
