A novel plant hairpin-like defense polypeptide named EcAMP3 was isolated from latent barnyard grass (Echinochloa crusgalli L.) seeds. The native peptide and its recombinant analogue were characterized.

DNA samples obtained from the populations of the Red Data Book species Bellevalia sarmatica (Georgi) Worovow from Volgograd oblast were examined using RAPD and AFLP analyses. DNA marking revealed considerable differences in the levels of interpopulation and intraspecific polymorphism of the Bellevalia. Furthermore, RAPD analysis, despite of lower levels of interpopulation polymorphism identified, made it possible to obtain clearer data on population subdivision upon statistical treatment of the results.

Three novel antimicrobial peptides designated ToAMP1, ToAMP2 and ToAMP3 were purified from Taraxacum officinale flowers. Their amino acid sequences were determined. The peptides are cationic and cysteine-rich and consist of 38, 44 and 42 amino acid residues for ToAMP1, ToAMP2 and ToAMP3, respectively.

We have analyzed genetic effects of heterologous plant genes insertion on genome functioning of higher plants, belonging to different systematic groups (tobacco, Arabidopsis). Plants of different species were responding differently to the insertion of the same transgene, which is likely to be associated with the location of alien DNA insertion and could manifest in morphological changes spectrum and target gene expression level.

The possibility of using RAPD and AFLP methods for genetic monitoring of populations of Matthiola fragrans (Bunge), a species included in the Red Book of the USSR, was shown for the first time. An analysis of inter- and intrapopulation and interspecies genome polymorphism was performed. Differences in the genetic structure of Matthiola populations from various geographical collection points were revealed.
