... 2004) Abstract – The possibility to use chloroplast microsatellites (cpSSRs) instead of restriction analysis of PCR-amplified DNA fragments to differentiate oak populations was tested in two ... The principle has been extended to the chloroplast genome in a vari- ety of species [18, 22]. The chloroplast genome is a useful source of markers for genetic studies of pl...
