We report the first case of plastid chimera within the Actinidia genus, where plastid inheritance was believed to be paternal. The heterogeneity of chloroplast DNA observed in the hexaploid Actinidia deliciosa cultivar D uno involves the presence or absence of a particular MspI restriction site in the region between the psbC gene and the tRNA-Ser(UGA) gene. The heterogeneity was first observed using restriction fragment length polymorphism and then confirmed through cloning and sequencing. The analysis of the cloned fragments revealed the presence of two haplotypes: the most frequent type was found in 123 (88.5%) out of a total of 139 colonies screened. Partial sequences of the psbC-trnS fragment from both haplotypes revealed that the polymorphism occurs within the coding region of the psbC gene and consists of a synonymous transition. A contamination-free cross involving D uno as the male parent produced only plants characterized by the most frequent haplotype, indicating either selection bias against the rare type or more likely fixation of the frequent type in tissues leading to the formation of the male gametes. The MspI restriction profiles performed on various tissues suggest that the rarer type is absent from the histogenic layer LII and that D uno is a periclinal plastid chimera.
