Genetic features of the formed population of the genus Eisenia worms

Abstract

It is known that molecular genetic methods can provide researchers with new, more accurate means for differentiating species of earthworms and determining phylogenetic distances among them. Therefore, using neutral molecular markers, ISSR (Inter-Simple Sequence Repeat) examined the internal genetic polymorphism of genus Eisenia rainworms from the vermiculture array of the Biotechnology Department of the Ukrainian State Chemical Technology University, the parent forms of which were irradiated with an LGN-208B laser for different temporary exposures and cultivated on different organic substrates. Studies have shown that the line of animals has a fairly high level of heterogeneity despite the fact that it was bred from six individuals of the same array. The laser radiation action and the hard substrate during cultivation (bottom deposits) appeared as powerful factors of selective pressure.
