The genus Picea is located from temperate to Taiga (boreal) regions of
northern hemisphere from subtropical to high altitude with 34 species. Picea
orientalis is endemic to Eastern Black Sea Mountainous region of Turkey and
Western Caucasus.
To determine the genetic relatedness within Picea orientalis populations, as
well as the relationship between other Pinaceae species from database,
populations were sampled from 15 different locations within the natural range
of species and grouped into 5 depending on several criteria. In order to
evaluate the genetic structure of the taxon, non-coding trn and matK regions of
choloroplast DNA (cpDNA) were sequenced.
According to genetic diversity analysis of 15 Picea orientalis populations with
respect to trn and matK regions, there is not much variation among
populations. Among 3 non-coding trn and the matK region, there is only one
variable site which was parsimony informative.
The results indicated that the populations from Artvin had the highest
divergence. In this study, the genetic divergence of Picea orientalis from other Pinaceae species were also observed. According to the results obtained from
trnV region the studied Picea orientalis observed to display a close
relationship with Larix and distinct from other Pinaceae especially Pinus
genus. This result is unrepresentative due to the results of other studies.
Moreover, as a result of analysis with trncd-ef region, the studied Picea
orientalis populations possessed close relationship with species from clade
Picea. Moreover, based on molecular clock estimations the studied Picea
orientalis populations had close relationships with the species form Asia.
Finally, the relationship of Picea orientalis with other Picea species were
analyzed with respect to matK region. The result is consistent with the results
of trncd-ef region and also with other studies.
