ABSTRACT
Iran is the original source and one of the important places for diversity of Astragalus species. Astragalus gossypinus species, which is the producer of tragacanth, belongs to papilionaceae family, mostly is spread in Asia. Alborz and Zagros heights are the most important inhabits of the tragacantha in Iran. Astragalus's inhabits in Isfahan covers around 31/3% area of this province. The morphological and ecological aspects Astragalus gossypinus is well investigated. In the present study, genetic characteristics of Astragalus gossypinus subpopulations are considered for further evaluation. This comparative study can be used in selection of the generation, production of high quality of tragacanth based on Astragalus places of growth. Thus, Astragalus gossypinus's samples were collected from six sites of its inhabits in Isfahan province. The whole genome was extracted by CTAB method and the extracted DNA quality was examined on electrophorus gel. A part of CNGC4 gene from different samples was amplified for further sequencing. Multi-alignment analysis of the sequences indicated a genetic similarity among Astragalus gossypinus subpopulations. Data indicated that the genotypes of subpopulations are identical. Thus we concluded that any variation in quantity and quality of produced tragacanth is due to alteration in environment of these subpopulations.
