Abstract: | Summary The plastid DNAs of the species Daucus carota (ssp. sativus, libanotifolia, gingidium), D. maximus and D. muricatus were compared by restriction enzyme analysis. A number of restriction fragment length polymorphisms (RFLPs) were observed. As expected from taxonomic data the degree of plastid DNA homology between D. carota and D. maximus is significantly higher (97%) than between D. carota and D. muricatus (70%). On the basis of RFLPs of plastid DNA the mode of plastid inheritance in interspecific crosses between D. muricatus and D. c. sativus was analysed. The results clearly indicate paternal plastid inheritance. Thus Daucus is the second genus among angiosperms transmitting predominantly male plastids. |
