The genus Onobrychis Mill. is one of the most economically important members of the family Fabaceae, which has a complicated infrageneric taxonomy. The genus has been traditionally divided into two subgenera, in which species of each subgenus have been classified in some sections. In the present study, the macro- and micro-morphological characteris...

... Forests are considered complex ecosystems with high levels of biodiversity that play an important role in carbon sequestration and soil and water management. They have a critical role in economic, aesthetic and cultural values (Pourhosseini et al. 2020;Guo et al. 2023;Azizi et al. 2023). Unfortunately, human activities, such as deforestation and climate change are destroying forest ecosystems around the world. ...
Quercus brantii var. persica and Quercus infectoria are two economically and ecologically important oak species widespread in the Zagros forest, located in the northwestern and southwestern parts of Iran. An effective study of the genetic diversity and population structure of these genetic resources is still unexplored. In the present study, 48 accessions of the mentioned oak species collected from different regions of Kermanshah province were subjected to a study of genetic diversity and population structure using two sets of markers (inter-simple sequence repeats [ISSR] and CAAT-box derived polymorphism [CBDP]). CBDP markers showed greater efficiency in detecting polymorphism in the oak individuals studied. The analysis of molecular variance [AMOVA] showed that the genetic variation within species, as well as within regions per species, was higher than between species. Quercus brantii var. persica had the highest values for all indicators of genetic variability. Moreover, at the regional level, the Dalahoo populations in both species showed the highest genetic diversity using the ISSR markers. This population, along with Gilan-e-Gharb had the highest genetic diversity using the CBDP markers. The results indicate a high level of genetic diversity in isolated regions, which in turn promotes the formation of population structure. Therefore, this may contribute to further conservation and genetic improvement of Iranian oak germplasm.
