Abstract excerpt
Two cytoplasmic male-sterile plants (CMSI and CMSII) were obtained by protoplast culture in Nicotiana sylvestris. Both plants showed large deletions (up to 50 kb) in their mitochondrial DNA. Restriction maps of the reorganized regions suggested that the deletions occurred via two homologous recombination events (rec. 1 and rec. 2) in the parental mitochondrial genome. With the exception of nad5, no mitochondrial...
