Species identification and population structure analysis in Geranium subg. Geranium (Geraniaceae)
AbstractSpecies identification is fundamentally important within the fields of biology, biogeography, ecology and conservation. The genusGeraniumL. (Geraniaceae) comprises about 430 species distributed throughout most parts of the world. According to the most recent treatments, subg.Geraniumis the largest subgenus with over 370 species classified in ten sections. The subg.Geraniumis represented in Iran by 13 species. These species are grouped 3 sections. In spite vast distribution of manyGeraniumspecies that grow in Iran, there are not any available report on their genetic diversity, mode of divergence and patterns of dispersal.Therefore, we performed molecular (ISSR markers) and morphological studies of 102 accessions from 13 species ofGeranium(subg.Geranium) that were collected from different habitats in Iran. The aims of present study are: 1) can ISSR markers identifyGeraniumspecies, 2) what is the genetic structure of these taxa in Iran, and 3) to investigate the species inter-relationship? The present study revealed that combination of morphological and ISSR data can identify the species.
