A Pilot Study of Gene Expression Modulation from Antioxidant System of Killifish Austrolebias charrua After Exposure to Roundup Transorb

Roundup Transorb ® (RDT) is the most popular glyphosate-based herbicide (GHB) used in agriculture, and its impact extends to non-target organisms. The annual killifish Austrolebias charrua is an endangered species endemic to southern South America and inhabits temporary ponds. This study evaluates t...

Zusammenfassung:	Roundup Transorb ® (RDT) is the most popular glyphosate-based herbicide (GHB) used in agriculture, and its impact extends to non-target organisms. The annual killifish Austrolebias charrua is an endangered species endemic to southern South America and inhabits temporary ponds. This study evaluates the effects of RDT concentrations (0.065 and 5 mg/L GAE) on A. charrua exposed for 96 h. Gene expression of cat , sod2 , gstα , gclc , and ucp1 was evaluated on the liver and gills. Highlighting that even at low concentrations permitted by Brazilian legislation, the RDT can have adverse effects on A. charrua .
