GENOME VARIABILITY IN PLANT SOMATIC CELLS. 2. NATURAL VARIABILITY

V. A. Kunakh

Literature data on the genome variability in intact plant somatic cells to occur naturally and resultant from various influences were reviewed. Occurrence, reasons for appearence and biological implication of chimeric and mixoploid forms, peculiarities of the genome variability among hybrids, haploids and polyploids, variability during injuries, graftings and other stress challenges were estimated. Analysis was focused upon putative reasons, mechanisms and ways for control of this variability. Key role of hormonal system in control and regulation of levels and trends in genome variability of somatic plant cells, genetic structure of organism's cell populations is substantiated.
