Bacillus thuringiensis is an insect pathogen that is widely used as a biopesticide (E. Schnepf, N. Crickmore, J. Van Rie, D. Lereclus, J. Baum, J. Feitelson, D. R. Zeigler, and D. H. Dean, Microbiol. Mol. Biol. Rev. 62:775-806, 1998). Here we report the finished, annotated genome sequence of B. thuringiensis Al Hakam, which was collected in Iraq by the United Nations Special Commission (L. Radn...

We report here the complete annotated 6,035,547-bp draft genome sequence of Bacillus thuringiensis INTA Fr7-4. This strain contains three cry8 and two vip1 and vip2 insecticidal toxin genes.

We report the draft genome sequences of two insecticidal strains against lepidopteran pests, Bacillus thuringiensis serovar kurstaki strain BP865, an isolate from the South Korean phylloplane, and strain HD-133, a reference strain of B. thuringiensis serovar aizawai.

Bacillus thuringiensis NBIN-866, a Gram-positive bacterium, was isolated from soil in China. We announce here the draft genome sequence of strain B. thuringiensis NBIN-866, which possesses highly nematocidal factors, such as proteins and small molecular peptides.

We succeeded in hyperproduction of Bacillus thuringiensis phosphatidylinositol-specific phospholipase C (PIPLC), using a Bacillus brevis 47 expression system. The recombinant B. thuringiensis PIPLC was expressed under the control of the middle wall protein gene promoter in B. brevis expression vector pNU211. A large amount of recombinant PIPLC (0.4 g per liter culture) was secreted into the med...

Bacillus thuringiensis has been widely used as a biopesticide for a long time. Here we report the finished and annotated genome sequence of B. thuringiensis mutant strain BMB171, an acrystalliferous mutant strain with a high transformation frequency obtained and stocked in our laboratory.

Five original strains of entomopathogenic bacteria with insecticidal activity against mosquito larvae of the genera Aedes, Culex and Anopheles have been isolated from natural conditions in Armenia and characterized. According to morphological, physiological and biochemical parameters, all isolates were identified as Bacillus thuringiensis spp. israelensis (Bti). High larvicidal activity has bee...

Gram-negative bacteria can communicate with each other by N-acyl homoserine lactones (AHLs), which are quorum-sensing autoinducers. Recently, the aiiA gene (encoding an enzyme catalyzing the degradation of AHL) has been cloned from Bacillus sp. strain 240B1. During investigations in the course of the ongoing Bacillus thuringiensis subsp. morrisoni genome project, an aiiA homologue gene in the g...

The histochemical effects of the lethal concentration that kills 50% of larvae (LC50) of three biological agents, abamectin, Bacillus thuringiensis and spinosad on the carbohydrates (polysaccharides), proteins, nucleic acids and lipids content of the midgut and fat bodies of Culex pipiens 2nd instar larvae were studied. The results showed that the three tested compounds reduced the carbohydrate...

The nucleotide sequences of 3 homologous crystal protein genes (cry A1,A2,A3) from Bacillus thuringiensis subsp. kurstaki and subsp. thuringiensis have been reported previously (1, 2, 3, respectively). We report the nucleotide sequence of an additional crystal protein gene {cry hi) from B. thuringiensis subsp. thuringiensis strain HD2 that differs markedly in the aminoterminal region from the 3...
