DNA FRAGMENT DETERMINING OGURA STERILITY AND ENCODING CYTOPLASMIC MALE STERILITY GIVEN IN MITOCHONDRIAL PLANT GENOME AND DNA PROBE FOR HYBRIDIZATION WITH THIS DNA FRAGMENT Russian patent published in 1998 - IPC

FIELD: molecular biology, biochemistry, genetics. SUBSTANCE: DNA fragment can be used for cytoplasmic male sterility making by its insertion into plant genome and for construction of transgenic plants exhibiting cytoplasmic male sterility. To isolate and detect this fragment DNA probe containing at least 10 successive nucleotides labeled with radioactive or nonradioactive agents is used. Nucleotide sequences of DNA fragment and DNA probe are given. EFFECT: improved method of preparing. 2 cl, 6 dwg, 2 tbl, 6 ex
