title: [Variation of the cytoplasm type in sugar beet (Beta vulgaris L.) upon inbreeding. The influence of hybridization].
abstract: Hybrid combinations of inbred sugar beet lines that undergo conversion of N-cytoplasm into S-state were screened for the marker mitochondrial genes atpA and atp6. The involvement of nuclear factors into cytoplasm conversion and possible identity of these factors in different lines have been studied. The cytoplasm conversion factor was localized to nucleus. In different lines with cytoplasm conversion, the nuclear conversion factors are not identical. The state of the mitochondrial genome is normalized after outcrosses with plants having the stable cytoplasm.
