After 15 years of cultivation of Panax ginseng, transgenic cell cultures were shown to express rolC gene at a high level. We determined that the rolC gene underwent mutagenesis. In particular, from one to four nucleotides were changed for the whole gene sequence (540 bp). These substitutions were synonymous in half of the cases or resulted in the modification of single amino acids in the rolC-encoded protein. With the example of B-1,3-glucanases we showed that long cultivation and the observed changes in nucleotide sequences of the transgene did not inhibit the activating effect of rolC on enzymatic activity of B-1,3-glucanases.
