✦ Synopsis
Previous RFLP-analysis of mtDNA isolated from different lines and cultivars of Vicia faba with respect to variability of the coxII gene revealed two types of mitochondrial genome: one with a normal coxII gene and the other with both normal coxII and chimeric coxII-orf192 genes. In this study we analyzed other regions of these two types of mitochondrial genome and found significant differences in the arrangement of regions around the coxII, coxIII, cob, rrn26 and atpA genes. More detailed analysis of the rrn26 and atpA gene regions showed that these genes are associated with recombinationally active repeats. Restriction maps of the rrn26 and atpA gene regions in different recombinative variants are presented.
