Investigation of Genotoxic Potentials of Some Fungicides by Drosophila SMART and KOMET Methods

Abstract

Many new pesticides are produced for use every year. Fungicides, one of the important subgroups of pesticides, are used to protect agricultural products from fungal infections. However, studies on the genotoxic potential of fungicides are still very limited. In this study, the genotoxic potentials of four commonly used fungicides (metiram, kresoxim-methyl, propamocarb and hymexazol) were investigated using the Drosophila Somatic Mutation and Recombination Test (SMART) and the Drosophila Single Cell Gel Electrophoresis Test (Drosophila Comet Test). Drosophila, which has been widely used in genetic studies in recent years, provides a powerful system in the use of genetic and molecular approaches in human genetic diseases research. As a model organism, Drosophila is in many ways similar to human systems. According to the results obtained from the study, it was determined that 4 fungicides whose genotoxic effects were investigated by SMART method did not induce genotoxicity. In the KOMET experiment, it was determined that the studied fungicides caused DNA single strand breakage. This study provides new data on the potential effects of pesticides on human health and possible genetic diseases.

Bazı Fungusitlerin Genotoksik Potansiyellerinin Drosophila SMART ve KOMET Yöntemleri ile Araştırılması

Abstract

Her yıl birçok yeni pestisit kullanım amacıyla üretilmektedir. Pestisitlerin önemli alt gruplarından biri olan fungusitler, tarımsal ürünleri fungal enfeksiyonlardan korumak amacıyla kullanılmaktadır. Bununla birlikte fungusitlerin genotoksik potansiyelleri hakkındaki çalışmalar hala çok sınırlıdır. Bu çalışmada, yaygın kullanılan dört fungusit’in (metiram, kresoxim-methyl, propamocarb ve hymexazol) genotoksik potansiyelleri Drosophila Somatik Mutasyon ve Rekombinasyon Testi (SMART) ve Drosophila Tek Hücre Jel Elektroforezi Testi (Drosophila Komet Testi) kullanılarak araştırılmıştır. Son yıllarda genetik çalışmalarda yaygın olarak kullanılan Drosophila, insan genetik hastalıkları araştırmalarında, genetik ve moleküler yaklaşımların kullanılmasında güçlü bir sistem sağlamaktadır. Model organizma olarak Drosophila birçok açıdan insan sistemleri ile benzer yönler göstermektedir. Çalışmadan elde edilen sonuçlara göre genotoksik etkisi SMART yöntemi ile araştırılan 4 fungusitin genotoksisiteyi indüklemediği tespit edilmiştir. KOMET deneyinde ise çalışılan fungusitlerin DNA tek iplik kırığına yol açtığı belirlenmiştir. Bu çalışma pestisitlerin insan sağlığı ve olası genetik hastalıklar üzerine potansiyel etkileri hakkında yeni veriler sunmaktadır.
