An M2e peptide of the H5N1 A/Chicken/Kurgan/05/2005 avian influenza virus has successfully been synthe­sized in transgenic tobacco plants. The N-terminal segment of M2 protein, 22, 30 or 43 amino acids in length including the M2e peptide (М122, М130 and М143 variants, respectively), was translationally fused with the N-terminus of β-glucuronidase in the plant expression vector of pBI121. The nucleotide sequence of the target fragment was synthesized by ligation from synthetic oligonucleotides, its codon composition being previously adapted for the expression in plants. Tobacco plants were successfully transformed with the obtained vectors (pBIM122, -130 и -143, respectivily). In the plants transformed with pBIM143, the fused protein М143-β-glucuronidase was not produced which is possibly a result of the occurrence of an M2 protein transmembrane domain (25—43 aa of M2) in this construct. In the pBIM122- and pBIM130-transformed plants, the target peptide M2e was expressed as a part of the fused proteins of М122-β-glucuronidase and М130-β-glucuronidase, respectively, as was detected by Western-blot analysis. These proteins occurred as bands of the expected size without apparent degradation. As a result, the M2e peptide of the H5N1 avian influenza virus was successfully synthesized for the first time in nuclear-transformed transgenic plants. The obtained results will be used in designing of transgenic plants-based edible anti-influenza vaccine.
