摘要: A comparative analysis of the presence minicircular DNA CCCIB in 16 different lines and cultivars fertile Vicia faba L. plants was conducted. It found that copy number ranged from several copies per mitochondrial genome to — probably zero, depending on cultivar or line. Fertility these cases not altered. We chose 10 among analysed. Mitochondria five contained about two molecules one CCCIA. The sixth at times lower. In last four could be identified. Copy CCC2 ten chosen revealed eight quantitiy equal However, other lower quantity CCC2. Parallel we observed an increase sequence homologous CCC2, which first only minor quantities. Comparative restriction notable rearrangement events DNAs being investigated. did find any correlations between patterns fragments CCCIB. some cases, rearrangements genomes caused a duplication sequences Zea mays coxII gene.
