▪ Abstract This review examines potential impacts of transgenic cultivars on insect
population dynamics and evolution. Experience with classically bred, insecticidal cultivars …

Bacillus thuringiensis (Bt) is a gram-positive spore-forming soil microorganism. Because the
insecticidal activities of Bt are well known, it has been used as a tool for insect pest control …

Members of the genus Bacillus are widely used as sources of industrial enzymes, fine
biochemicals, antibiotics, and insecticides (for a review, see reference 27). One of these …

Bacillus thuringiensis, known as Bt, is a spore-forming bacterium that occurs naturally in soil
and that produces highly specific insecticidal proteins called Cry proteins. These proteins …

Three species of the Bacillus cereus group (Bacillus cereus, Bacillus anthracis, and Bacillus
thuringiensis) have a marked impact on human activity. Bacillus cereus and B. anthracis are …

The classification of Bacillus thuringiensis strains has been revised and updated based on
flagellar antigens which have been in use for many years. Sixty‐nine serotypes and 13 sub …

Over the years it has been important for humans to control the populations of harmful insects
and insecticides have been used for this purpose in agricultural and horticultural sectors …

The polymerase chain reaction (PCR) is a molecular tool widely used to characterize the
insecticidal bacterium Bacillus thuringiensis. This technique can be used to amplify specific …

Transcription of the Bacillus thuringiensis cryIIIA toxin gene is initiated at nucleotide
position− 558 (relative to the cryIIIA start codon). However, the major cryIIIA transcript is an …

The promoter region of the cryIIIA toxin gene of Bacilius thuringiensis is composed of at least
three domains: an upstream region extending from nucleotide positions‐635 to‐553 (with …
