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...
The replication region of the Bacillus thuringiensis plasmid, pHT1030, was treated with hydroxylamine. Various copy-number mutants were selected and subsequently used to construct shuttle vectors with multiple cloning sites. These recombinant plasmids are very stable and allowed the cloning of a delta-endotoxin-encoding gene in B. thuringiensis. Comparison between gene expression level and vect...
Bacillus thuringiensis subsp. israelensis produces a potent mosquitocidal protein, Cry4A. We have identified a 15-bp catabolite responsive element (cre), overlapping the -35 element of the cry4A promoter. Changing a guanine to adenine at position -49 in the promoter abolished glucose catabolite repression of cry4A and enhanced promoter activity two- to threefold. This cis regulatory element is ...
