Potentiation of Catalase-Mediated Plant Thermotolerance by N-Terminal Attachment of Solubilizing/Thermostabilizing Fusion Partners.

Catalase (CAT) plays a crucial role in plant responses to environmental stresses and maintaining redox homeostasis. However, its putative heat lability might compromise its activity and function, thus restricting plant thermotolerance. Herein, we verified Arabidopsis CAT3 was of poor thermostability that was then engineered by fusion expression in .
