Bacillus thuringiensis crystal (Cry) proteins are the most widely used biological insecticides in the world. Their value in safely controlling insects that destroy crops and transmit human diseases is well established.Here, we reviewB. thuringiensisCry proteins as novel anthelmintics with a unique mode of action. In laboratory studies, Cry proteins are highly effective against a broad range of ...
Bacillus thuringiensis (Bt) crops, genetically modified to express insecticidal toxins that target key pests of corn, cotton, rice, potato, and other crops, have been rapidly adopted and have become dominant fixtures in agroecosystems throughout the world. Due to the constitutive nature of Bt toxin expression, insecticidal proteins may be found in nearly all plant tissues, presenting multiple s...
Sichuan basin, situated in the west of China, is the fourth biggest basin in China. In order to describe a systematic study of the cry2-type genes resources from Bacillus thuringiensis strains of Sichuan basin, a total of 791 Bacillus thuringiensis strains have been screened from 2650 soil samples in different ecological regions. The method of PCR-restriction fragment length polymorphism (PCR-R...
The draft genome sequences of six Bacillus strains, isolated from the International Space Station and belonging to the Bacillus anthracis-B. cereus-B. thuringiensis group, are presented here. These strains were isolated from the Japanese Experiment Module (one strain), U.S. Harmony Node 2 (three strains), and Russian Segment Zvezda Module (two strains).
The genetic relationships of Bacillus cereus and of the Bacillus thuringiensis serovars were assessed from measurements of DNA reassociation. A study of 8 to 10 strains each of 13 of the most commonly encountered serovars revealed that the levels of intragroup DNA relatedness for most serovars ranged from 90 to 100%. In contrast, B. thuringiensis serovars canadensis and kenyae consisted of two ...
In 2010, H14 influenza A viruses were recovered from clinically normal sea ducks in the United States. These are the first H14 isolates recovered in the Western Hemisphere and represent the only documented H14 influenza A viruses isolated since the original isolates were recovered from near the Caspian Sea during 1982.
Soil from George Town, Grand Cayman Island, yielded the bacteriophage Belinda, isolated on Bacillus thuringiensis DSM 350. We present here the analysis of the complete genome sequence of 162,308 bp, with 298 predicted genes. The genome also contains three tRNA genes. Belinda belongs to the C1 cluster of Bacillus phages.
Verticillium wilt causes severe yield losses in a broad range of economically important crops worldwide. As many soil fumigants have a severe environmental impact, new biocontrol strategies are needed. Members of the genus Bacillus are known as plant growth-promoting bacteria (PGPB) as well as biocontrol agents of pests and diseases. In this study, we isolated 267 Bacillus strains from root-ass...
Inclusion bodies isolated from Spo Cr mutants of Bacillus thuringiensis were toxic for larvae of the European corn borer. Probit analysis revealed comparable toxicity between wild-type crystals (isolated from B. thuringiensis subsp. kurstaki) and crystals produced from two spore-free mutants of the same subspecies. Death of the larvae was due to starvation, presumably through delta-endotoxin-in...
