Abstract: | We used PCR-RFLP analysis of the chloroplast DNA of the genus Abies (family Pinaceae), to determine if the method could be employed to detect inter-specific variation in this genus and to study how the variation
was distributed in different regions of the genome. Ten different chloroplast DNA regions, consisting of coding and non-coding
DNA sequences, were amplified with specific primers in ten different Abies taxa. The amplification products were digested with several restriction enzymes. The results showed that the chloroplast
genome is highly variable in most of the investigated taxa and contains multiple variable regions that appear to be distributed
throughout the whole genome. Species-diagnostic markers were found for four of the ten investigated species. Unexpectedly,
intra-specific variation was also detected in four species. It is likely that further studies, including larger sample sizes
and/or more powerful methods for the detection of chloroplast DNA variation, will reveal additional variation for this genus.
