Abstract
It is shown by electron microscopy and biochemical methods that mitochondrial DNA (mtDNA) of Beta vulgaris L. is multicomponent and consists of high molecular DNA (~500 kb) and minicircular plasmid-like DNA molecules (1.3, 1.4 and 1.6 kb). High molecular mtDNA when not entirely free of proteins is presented by resembling chro-momers of globular and rosette-like structures. The typical rosette has a protein core and stemming from it DNA loops. The globules and rosettes are interconnected between themselves by thick and thin DNA fibrils along which nucleosome- and nucleomere-like structures are regularly distributed. The plasmid-like DNA molecules are in super-coiled forms
