“…Two pairs of specific primers (Supplemental Table 1S) were designed respectively according to the DNA sequences of the Cry218-pht304 plasmid and PHKT2 recipient expression vector [10]. These amplified DNA fragments were mixed at a ratio of 1:3 (100 ng vector to 300 ng DNA fragments), and transformed into E. coli XL-10 Gold cells [11]. The recombinant plasmid was DNA sequenced to confirm the construction by TakaRa (Dalian, China).…”

To expand the usage of endophytes in agriculture and in forestry, the insecticidal gene cry218 of Bacillus thuringiensis was introduced into a poplar bacterial endophyte Burkholderia pyrrocinia JK-SH007. The cry218 gene was cloned by polymerase chain reaction (PCR) and was inserted into a PHKT 2 expression vector that was introduced into the bacterial endophyte JK-SH007. By using sodium dodecyl sulphate polyacryl amide gel electrophoresis (SDS-PAGE) and western blotting, we confirmed that the engineered bacterial endophyte was successfully constructed, and it harboured insecticidal function after the bioassay in planta. The toxicity of the expressed insecticidal protein was analysed on second instar silkworm. The regression equation showed that the median lethal concentration (LC 50) of the insecticidal protein was 0.77 (0.57-1.04) g/L at 72 h. The insecticidal bacteria genetically modified in this study have laid the foundation for further exploitation of biocontrol bacteria.

For many years the Gram-positive bacterium Bacillus megaterium has been used for the production and secretion of recombinant proteins. For this purpose it was systematically optimized. Plasmids with different inducible promoter systems, with different compatible origins, with small tags for protein purification and with various specific signals for protein secretion were combined with genetically improved host strains. Finally, the development of appropriate cultivation conditions for the production strains established this organism as a bacterial cell factory even for large proteins. Along with the overproduction of individual proteins the organism is now also used for the simultaneous coproduction of up to 14 recombinant proteins, multiple subsequently interacting or forming protein complexes. Some of these recombinant strains are successfully used for bioconversion or the biosynthesis of valuable components including vitamins. The titers in the g per liter scale for the intra- and extracellular recombinant protein production prove the high potential of B. megaterium for industrial applications. It is currently further enhanced for the production of recombinant proteins and multi-subunit protein complexes using directed genetic engineering approaches based on transcriptome, proteome, metabolome and fluxome data.
