Hybrid plasmids of two types containing S1 and S2-sequences of mitochondrial maize var. BUP 44 MC are obtained. The first type contains fragments, and the second one – the full sequences with the inverted repeated sequences in the centre of molecules. Recombinant plasmids of the second type have been shown not to be ARS-elements for yeast cells. While introducing hybrid plasmid into intact maize plants the low-weight fractions are found in mitochondrial DNA.
