| Popis: | Restriction fragment length polymorphism, polymerase chain reaction-restriction fragment length polymorphism and simple sequence repeat (SSR or microsatellites) analyses were performed to detect chloroplast DNA polymorphisms between two ash species, Fraxinus excelsior and F. angustifolia. Only one SSR locus was found to be polymorphic, confirming the very close relatedness of these species. Inheritance of this marker was studied in hybrids obtained from controlled crosses between the two tree species. Results indicated, for the first time in Oleaceae, that chloroplasts are maternally inherited. This chloroplast SSR marker is now used concomitantly with nuclear markers to analyse ash populations in sympatric areas. |
