Arabidopsis thaliana Oxoprolinase 1 (AtOXP1) maintains glutamate homeostasis, promotes arsenite and mercury tolerance, and reduces accumulation in plants.

The Plant journal : for cell and molecular biology - 1 Apr 2025

Abstract excerpt

Glutathione (GSH) plays a crucial role in cellular redox regulation and enhancing plant survival under heavy metal toxicity. In plants, GSH homeostasis is managed through the γ-glutamyl cycle, though the genes involved in GSH degradation and recycling are not fully understood. Here, we have characterized the Arabidopsis oxoprolinase 1 (AtOXP1) gene for its role in providing tolerance to arsenite (AsIII) and...
