Popis: Development of modern agriculture and biotechnology is closely connected with the use of novel and effective genetic engineering methods. Presently, non-viral nanoparticle-mediated plant transformation methods gain more attention because of their stability, safety, and convenience of performance. In this work, new polymeric dimethylaminoethyl metacrylate (DMAEM)-based polymers were synthesized and investigated for their properties in gene delivery. Formation of stable complexes between TN 83/6, TN 84/5, DLM-9-DM and LM-8-DM polymers and plasmid DNA, as well as the DNA protection by the PDMAEM polymers against nuclease degradation were confirmed by electrophoresis in agarose gel. In addition, model organisms Allium cepa and Nicotiana tabacum L. were studied to evaluate cytotoxic effect of the PDMAEM carriers. The created PDMAEM-based carriers were effective in delivery of plasmid DNA into moss and tabacco protoplasts (obtaining stable transformants of Ceratodon purpureus moss, as well as in transient expression of the reporter yfp gene product in N. tabacum protoplasts). Thus, novel PDMAEM-based polymers were shown to be promising carriers for delivery of DNA into plant cells, and carriers possess high potential for further applications in this field.
