Inheritance of the chloroplast genome in Sorbus aucuparia L. (Rosaceae).
Chloroplast DNA (cpDNA) inheritance was investigated in Sorbus aucuparia using progenies obtained from six controlled crosses between individuals of known haplotype. Polymerase chain reaction (PCR) amplification, followed by restriction analysis, was used to characterize 248 offspring for either of two polymorphic cpDNA fragments. All offspring exhibited the maternal haplotype, which indicates maternal inheritance of chloroplasts in S. aucuparia. Power analysis of the test showed that the frequency of paternal transmission of chloroplasts, if any, should not exceed 1.84% (with 99% confidence).
