We report the applicability of the Hypoxanthine Guanine Phosphoribosyl Transferase (HGPRT) gene to test the potential mutagenic activity of Teucrium apollinis (TA).Genotoxicity of low dose (LD) 50µl and high dose (HD) 250µl of fixed oil extracted from TA were examined using asexual cell (oidia) of Coprinopsis cinerea.Surprisingly, survival of wild type cells was significantly decreased to 45.8 and...
