摘要

Roundup Transorb® (RDT) 是农业中最常用的草甘膦类除草剂 (GHB)，其影响波及非目标生物。一年生鳉鱼 Austrolebias charrua 是南美洲南部特有的濒危物种，栖息于临时池塘中。本研究评估了滴滴涕浓度（0.065 和 5 毫克/升 GAE）对暴露 96 小时的 A. charrua 的影响，并评估了肝脏和鳃中 cat、sod2、gstα、gclc 和 ucp1 的基因表达。结果表明，即使在巴西法律允许的低浓度条件下，RDT 也会对 A. charrua 产生不利影响。

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 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.
