摘要/ Abstract摘要:瘦肉毒霉(Leptinotarsa decemlineata, Ld)对化学和生物杀虫剂均产生抗药性。寻找能增加植物适应潜力的微生物共生体是很重要的。结果表明，苏云金芽孢杆菌B-5351的内生细胞能提高马铃薯Ld幼虫的死亡率，激活蛋白酶抑制剂及其蛋白产物基因的转录，而“低内生”的苏云金芽孢杆菌B-5659则能产生高效的虫毒素。

Producing Cry-Toxins Endophytic Bacteria as an Alternative to Transgenic Plants to Protect Potato Plants against Colorado Potato Beetle

Abstract Leptinotarsa decemlineata ( Ld ) can develop resistance to chemical and biological insecticides. It is important to search for microbial symbionts of plants that increase their adaptive potential. It was shown that the endophytic cells of Bacillus thuringiensis B-5351 increases Ld larvae mortality and activates the transcription of genes of proteinase inhibitors and their protein products in potato plants after pest damage, in contrast to the “low endophytic” B. thuringiensis B-5659, which produces highly effective insectotoxins.

期刊介绍： Molecular Genetics, Microbiology and Virology is a journal that covers most topical theoretical and applied problems of molecular genetics of pro- and eukaryotic organisms, molecular microbiology and molecular virology. An important part the journal assigns to investigations of the genetic apparatus of microorganisms, searching for forms of genetic exchange, genetic mapping of pathogenic causative agents, to ascertainment of the structure and functions of extrachromosomal factors of heredity and migratory genetic elements, to theoretical studies into the mechanisms of genetic regulation. The journal publishes results of research on molecular and genetic bases of an eukaryotic cell, functioning of chromosomes and chromatin, nature of genetic changes in malignization and a set of hereditary diseases. On the pages of the journal there is covered the formulation of molecular bases of virology including issues of integration of viral and cellular genomes, and issues of persistence. The journal plans to put materials on genetic engineering, envisaging synthesis and isolation of genes from natural reservoirs, creation of plasmid- and virus-based vector, production of recombinant DNA molecules, the creation of Gene Banks for Microbes, animals, and human; and also on biotechnological production of hormones, components of antiviral vaccines, diagnostic and therapeutic preparations.
