Abstract

In this study, the possible genotoxic effects of ethyl methanesulfonate (EMS) which are one of alkylating agent and genoprotective effects of Rosa canina L. fruit water extract (RCwtr) was studied with Drosophila wing somatic mutation and recombination test (SMART). Five different application groups (distilled water, 1 mM EMS, 1% RCwtr, 3% RCwtr and 5% RCwtr) were formed with preliminary studies. 3-day-old transheterozygous larvae of mwh/flr3 genotype of Drosophila melanogaster were fed chronically on the Drosophila instant medium (DIM) including the application groups. The wing slides of normal wing (mwh/flr3) phenotype individuals were prepared and examined under light microscope (400X). As a result of experiments, the total clone frequencies of distilled water control group, 1 mM EMS, 1% RCwtr, 3% RCwtr and 5% RCwtr application groups were determined as 0.15, 3.55, 2.58, 2.78 and 2.20, respectively. The difference between distilled water control group and 1 mM EMS application group is statistically significant (P
