STRUCTURAL AND FUNCTIONAL CHARACTERS OF PLASMID-LIKE MITOCHONDRIAL MAIZE DNA

Summary

    Hybrid plasmids of two types containing SI 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. Re-combinant 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.
