Ethyl methanesulfonate ems

WebEthyl methanesulfonate (EMS) is a monofunctional ethylating agent that has been found to be mutagenic in a wide variety of genetic test systems from viruses to mammals. It has also been shown to be carcinogenic in mammals. Alkylation of cellular, nucleophilic sites by EMS occurs via a mixed SN1/SN2 reaction mechanism. While ethylation of DNA ... WebEthyl methanesulfonate (EMS) is a widely used chemical mutagen in plants as it gives a high frequency of point mutations. Hence, this study aimed to determine the lethal concentration 50 (LC 50 ) of EMS and the mutagenic effects of EMS on growth characteristics and morphological variations of N. cadamba derived from nodal explants.
