Abstract
To evaluate mutagenicity of Phosphinotricin Acetyltransferase(PAT) which is expressed by the glufosinate-resistance gene pat, in vitro reverse mutation test using Salmonella typhimurium, chromosome aberration test using chinese hamster lung(CHL) cells and in vivo micronucleus test of mice were performed. In the reverse mutation, the PAT did not induce mutagenicity in Salmonella typhimurium TA 98, TA 100, TA 1535, TA 1537 with and without metabolic activation at $5000{\mu}g/plate$. In the chromosome aberration test, the results showed no incidence of increased structural and numerical chromosome aberrations at any doses tested(100, 10, $1{\mu}g/mL$). In micronucleus test, the ratio of micronuclei was measured in polychromatic erythrocytes of bone marrow of male ICR mice intraperitoneally administrated with PAT(1250, 625, and 313 mg/kg), the results showed no incidence of increased micronucleated polychromatic erythrocytes (MNPCE). These results indicate that PAT might not have mutagenic potential in vitro and vivo systems.
