Bt protein

Ebook "Biocontrol of lepidopteran pests: Use of soil microbes and their metabolites (Soil biology, Volume 43)" describes the various applications of entomopathogenic soil microorganisms in the management and control of the devastating lepidopteran pest. An introduction describes the insecticidal properties of viruses, bacteria, fungi, nematodes and their metabolites, as well as their applications in the context of crop improvement.

Resistance of pest insect species to insecticides, including B. thuringiensis (Bt) pesticidal proteins expressed by transgenic plants, is a threat to global food security. Despite the western corn rootworm, Diabrotica virgifera virgifera, being a major pest of maize and having populations showing increasing levels of resistance to hybrids expressing Bt pesticidal proteins, the cell mechanisms leading to mortality are not fully understood.

We previously demonstrated that 6-benzylthioinosine (6-BT) could induce the differentiation of a subset of acute myeloid leukemia (AML) cell lines and primary AML cells regardless of their cytogenetics. In this study we investigated whether Wnt signaling pathways played roles in 6-BT-induced differentiation of AML cells.

Insecticidal δ-endotoxins of Bacillus thuringiensis have acquired great significance in recent years because of their specificity to target insects and toxicity at very low concentrations. Genes from B. thuringiensis have been the most successful group of genes identified for use in genetic transformation of crops for pest control on a commercial scale. Successes of plant transformation include most of major economic and vegetable crops. Polymerase chain reaction (PCR) is commonly used technique for the presence of transgene in the putative transformants by DNA amplification.

Bacillum thuringiensis (Bt) toxin produced in Cry1-expressing genetically modified rice (Bt rice) is highly effective to control lepidopteran pests, which reduces the needs for synthetic insecticides. Non-target organisms can be exposed to Bt toxins through direct feeding or trophic interactions in the field.

Pardosa pseudoannulata is a prevailing spider species, and has been regarded as an important bio-control agent of insect pests in farmland of China. However, the available genomic and transcriptomic databases of P. pseudoannulata and their venom are limited, which severely hampers functional genomic analysis of P. pseudoannulata.

Insect pests caused the yield loss in agricultural crops and forestry plants world widely. Commercial biopesticides based on Bacillus thuringiensis (Bt) have been used for pest management. The most important factor that makes Bt as commercial biopesticides is its remarkable ability to produce large quantities of larvicidal proteins (known as Cry protein or delta-endotoxin) that form crystalline inclusion bodies during sporulation.

Field experiments were conducted at Krishi Vigyan Kendra, Veterinary College and Research Institute, Namakkal during winter irrigated season of 2015- 2016 and 2016-2017 to study the different fertilizer levels in Bt cotton based annual legume fodder intercropping systems. The treatments comprised of intercropping systems in the main plot (C1- Bt cotton alone; C2- Bt cotton + fodder cowpea; C3-Bt cotton + horse gram; C4- Bt cotton + moth bean; C5- Bt cotton + pillipesera) and different fertilizer levels in sub plot (F1-100% RDF; F2- 125% RDF; F3-150% RDF).

Cotton yield losses due to insect pests are estimated to be around 10 to 14 per cent every year. These insect protected cotton varieties contain a naturally occurring substance, Bacillus thuringiensis (Bt) protein which has been used as an ingredient in safe and effective biological sprays for more than 50 years.

The two year experiments were conducted under field and in the laboratory with fifteen cotton cultivars as treatments replicated thrice. Observation on major sucking pest viz., aphid, leafhopper, whitefly and thrips were recorded on five plants and biochemical constituent viz., crude protein, total phenols and total soluble sugar were estimated from the leaves of cotton cultivars collected at 45 and 60 days after emergence. The biochemical were estimated by standard methods and correlated with sucking pests.

Bacillus thuringiensis is produced crystalline proteins, these proteins were used in transgenic cotton to control insect pest. During present study, two trials were with 09 treatments plots of Bt cotton plants viz., 7, 14 and 21gm/m.sq.

A gene encoding thermostable Lon protease fromBrevi-bacillus thermoruberWR-249 was cloned and characterized. TheBr. thermoruberLon gene (Bt-lon) encodes an 88 kDa protein characterized by an N-terminal domain, a central ATPase domain which includes an SSD (sensor- and sub-strate-discrimination) domain, and a C-terminal protease domain. The Bt-lon is a heat-inducible gene and may be controlled under a putativeBacillus subtilisr A -dependent promoter, but in theabsenceofCIRCE(controlling inverted repeat of chaperone expression)....

Bacillus Thuringiensis (Bt): A pest control product that is made from beneficial bacteria and applied as a spray to kill caterpillars. Sold under a variety of names such as Thuricide, Dipel, and Bio-Worm and others. Use Bacillus thuringiensis ëIsraelensisí (Bti) in water for the control of mosquito larvae and for control of fungus gnats in pot plants in office buildings. Use Garrett Juice with Bt for extra effect. Molasses also helps. It provides protein and keeps insect-killing bacteria alive on the foliage longer ñ even during rain.
