Özet
An improved protocol for the isolation of DNA from dry material of some Hesperis specimens is described. The isolated DNA is suitable for random amplification of polymorphic DNA (RAPD) analysis. Different DNA extraction protocols were examined to determine which might yield DNA from dry leaf tissue of Hesperis specimens. The methods examined include the protocols with hexadecyltrimethylammonium bromide (CTAB) described by Doyle and Doyle (1987); sodium dodecyl sulfate (SDS) by Dellaporta et al. (1983); and CTAB and SDS, the modified minipreparation, by Dellaporta et al (1983). None of these procedures yielded DNA of suitable purity for RAPD assay. We established an improved procedure involving CTAB and enzymatic digestion of proteins and RNA. The recovery of DNA with an average yield of 25 mg/g of leaf material was possible with this procedure. RAPD bands, which could be used to distinguish among Hesperis specimens, were generated.
