Epigenetic and epiplastome variability in apozygotic progenies of sugar beet with 5-azacytidine

Soaking seeds in 5-azacytidine induced epigenetic and epiplastome variation in sugar beet. It hastens the early flowering of sugar beet, decreased the amount of not-flowering plants (flowerlcss, stemlcss), increased the number of second order branches in plants (epigenetic variability). 5-azacytidine influenced on the number of sub-cellular organelles in cytoplasm. It was also shown that 5-azacytidine reduces the chloroplasts number in stomata guard cells by 15–20% (epiplastome variability). It is possible that correlation exist between epiplastome and epigenetic variability in plants treated by 5-azacytidine.
