摘要

The influence of environmental xenobiotics leads to an increase in the frequency of gene mutations and chromosomal aberrations, as well as to a higher level of fluctuating asymmetry in Viciafaba, Arabidopsis thaliana, cultivated Ligustrum japonicum Thund., and Olea europea L. used as test systems. These alterations manifest themselves as arbitrary variations in ontogenesis. It has been found out in model experiments that damages to genetic structures with chemical toxicants causes chromosomal rearrangements, together with an increase in the fluctuating asymmetry of bilaterally represented characters in leaves, as a result of disturbances in regulatory functions. Fluctuating asymmetry is an informative and easily available test for quantitative estimation of the level of alterations in regulatory genome function. The parameters of asymmetry in leaves can be used as criteria to reveal the degree of ecological risk to generational and regulatory functions of genetic apparatus.
