A study of biodiversity using DSS method and seed storage protein comparison of populations in two species of Achillea L. in the west of Iran

Intarspecific and interspecific variations are the main reserves of biodiversity and both are important sources of speciation. On this basis، identifing and recognizing the intra and interspecific variations is important in order to recognition of biodiversity. This research was done to study biodiversity and electrophoresis comparison of seed storage proteins in the populations of the two species of the genus Achillea in Hamadan and Kurdistan provinces using of the method of determination of special station (DSS). For this purpose، 12 and 9 special stations were selected for the species A. tenuifolia and A. biebresteinii using the data published in the related flora. Seed storage proteins were extracted and then studied using electrophoresis techniques (SDS-PAGE). In survey of all special stations، 120 plant species were distinguished as associated species. The results of the floristic data for the both species determined six distinctive groups that indicated the existence of intraspecific diversity in this species. The result of analysis of ecological data and seed storage proteins for the two species was in accordance with the floristic data and showed six distinctive groups. The existence of the bands of no. 4، 5، 8، 12 and 13 in the special stations of A. tenuifolia and the bands of 14، 15 and 16 in the special stations of A. biebresteinii o separated the populations of the species in two quite different and distinctive groups.
