Ecotype-specific responses of Typha domingensis to microplastics: Antioxidant defense and biochemical adaptations in wetland ecosystems

Environmental Chemistry and Ecotoxicology
The inherent ability of plants to withstand microplastic (MP) stress is primarily governed by complex structural and physio-biochemical adaptations. In this study, the MP tolerance mechanisms of six naturally occurring ecotypes of Typha domingensis Pers.
