Abstract
The Arasbaran forest is one of the genetic hotspots of the biosphere due to its high species diversity, and the white oak species plays a special role in the composition and diversity of the biological elements of Arasbaran forests. In this regard, it is necessary and important to evaluate the genetic diversity of the identified seed production area of white oak. In this research, the genetic diversity within and between seven different white oak populations, including 49 different trees, was investigated using the SCoT molecular marker. A total of 129 alleles were observed for these markers, and 100% of the produced alleles were polymorphic. The number of alleles varied from 16 to 29, with marker SCoT41 having the highest number at 29 alleles and marker SCoT7 having the lowest number at 16 alleles. Analysis of molecular variance (AMOVA) showed that 90% of the observed genetic diversity was distributed within populations, while 10% occurred among populations, suggesting that genetic variability within populations was more significant than that among populations. Based on the UPGMA dendrogram, individuals were partitioned into six distinct clades, and according to the UPGMA and PCA patterns, geographical proximity has not played an important role in the formation of the genetic structure of these populations. This research has provided initial insight into the genetic diversity within and between different populations of the Arasbaran white oak species. As a result, it is suggested that, by studying other markers, useful information for conservation and management measures for this valuable species can be obtained.
