dc.description.abstractIn the present study, the combination of the micronucleus test with analysis of the activity of the rRNA genes in mutagen-treated Hordeum vulgare (barley) by maleic hydrazide (MH) cells was performed. Simultaneously fluorescence in situ hybridization (FISH) with 25S rDNA as probes and an analysis of the transcriptional activity of 35S rRNA genes with silver staining were performed. The results showed that transcriptional activity is always maintained in the micronuclei although they are eliminated during the next cell cycle. The analysis of the transcriptional activity was extended to barley nuclei. MH influenced the fusion of the nucleoli in barley nuclei. The silver staining enabled detection of the nuclear bodies which arose after MH treatment. The results confirmed the usefulness of cytogenetic techniques in the characterization of micronuclei. Similar analyses can be now extended to other abiotic stresses to study the response of plant cells to the environmentpl_PL
