Paternal inheritance of mitochondria and chloroplasts in Festuca pratensis-Lolium perenne intergeneric hybrids
Organelle inheritance in intergeneric hybrids of Festuca pratensis andLolium perenne was investigated by restriction enzyme and Southern blot analyses of chloroplast DNA (cpDNA) and mitochondrial DNA (mtDNA). All F1 hybrids exhibited maternal inheritance of both cpDNA and mtDNA. However, examination...

Summary: | Organelle inheritance in intergeneric hybrids of Festuca pratensis andLolium perenne was investigated by restriction enzyme and Southern blot analyses of chloroplast DNA (cpDNA) and mitochondrial DNA (mtDNA). All F1 hybrids exhibited maternal inheritance of both cpDNA and mtDNA. However, examination of backcross hybrids, obtained by backcrossing the intergeneric F1 hybrids to L. perenne, indicated thatboth uniparental maternal organelle inheritance and uniparental paternal organelle inheritance can occur in different backcross hybrids. |
