“…possess excellent characteristics and are extremely efficient for many agricultural, environmental and industrial applications. In agricultural (green) biotechnology, they exhibited superior pesticidal ability (Merritt et al 1989;Turner and Backman 1991;Powell and Jutsum 1993;Dingman 1994;Osburn et al 1995;Emmert and Handelsman 1999;Greene et al 2001;Nunez-Valdez et al 2001). In environmental applications they are used in enzyme immunoassays for the detection of specific pesticides (Zherdev et al 1997) or their mutagenic activity (Shiau et al 1981).…”

Plasmid transformation is an efficient and crucial biotechnological tool that enables the enhancement of many important microbial characters that would be beneficial in a lot of industrial, agricultural and environmental applications. In the present study, five Bacillus species (B. subtilis, B. cereus, B. alvei, B. circulans and B. pumilus) were investigated. They were isolated from agricultural soils of different local arid environments of the Kingdom of Saudi Arabia, identified and characterized for their plasmid content. The main objective of the present study was to enhance the production of alkaline protease in Bacillus circulans (the recipient strain) through plasmid transformation from B. subtilis (the donor strain). All the tested Bacillus strains successfully produced unique multiple (3, 4 and 5) spontaneous antibiotic resistant mutants against chloramphenicol, neomycin, rifampicin, streptomycin, kanamycin and tetracycline and all of which were mutated to Rif r strains. B. pumilus showed the highest resistance against five of the six tested antibiotics while both of B. alvei and B. circulans showed the lowest resistance to only three of the tested antibiotics. Results revealed that B. subtilis was the best among the tested species concerning the production of alkaline protease (90.2 U/ml) while B. pumilus was the lowest in activity (40.3 U/ml). Screening of plasmid content revealed the presence of one or two mega indigenous plasmids in all the tested species. The four transformant strains BC 1 , BC 2 , BC 3 and BC 4 resulting from plasmid transformation exhibited significant increases in the activity of alkaline protease and recorded 2.31-to 3-fold increases compared to the parent B. circulans cells and 2.11-to 2.75-fold increases compared to the donor cells of B. subtilis. They also acquired antibiotic resistance to tetracycline and chloramphenicol that was completely absent in the parent cells of B. circulans. Results revealed that plasmid transformation among the tested Bacillus spp. is a powerful technique that can be efficiently exploited to enhance alkaline protease production in the transformed Bacillus spp. compared to their wild strains and we recommend using the improved transformant strains for commercial and industrial purposes.

“…However, the sap-sucking hemipteran pests are not particularly susceptible to the Bt-derived toxins (4)(5)(6). Indeed, in some cases, chemical insecticides have to be applied to curtail damage caused by hemipteran pests on Bt transgenic crops, such that the benefit of using the insect resistant transgenic varieties is lost (7)(8)(9).…”

Although transgenic crops expressing Bacillus thuringiensis (Bt) toxins have been used successfully for management of lepidopteran and coleopteran pest species, the sap-sucking insects (Hemiptera) are not particularly susceptible to Bt toxins. To overcome this limitation, we demonstrate that addition of a short peptide sequence selected for binding to the gut of the targeted pest species serves to increase toxicity against said pest. Insertion of a 12-aa pea aphid gut-binding peptide by adding to or replacing amino acids in one of three loops of the Bt cytolytic toxin, Cyt2Aa, resulted in enhanced binding and toxicity against both the pea aphid, Acyrthosiphon pisum, and the green peach aphid, Myzus persicae. This strategy may allow for transgenic plant-mediated suppression of other hemipteran pests, which include some of the most important pests of global agriculture.aphid management | biotechnology | insect resistance
