Vitamin E in stress sensing and signaling

Vitamin E is a potent antioxidant, essential for plants as it is involved in stress sensing and signaling.

Vitamin E is mainly found in photosynthetic tissues as one of its main functions is to prevent the production of reactive oxygen species (ROS) at photosystem level, as well as to avoid damage of chloroplastic membranes. Nevertheless, vitamin E can also be found in non-photosynthetic tissues, where its main action is to alleviate lipid peroxidation from cellular membranes.

Our research aims to relate the production of vitamin E with environmental and developmental cues. Identify the site of production, along with the different conditions and molecules which regulate the biosynthesis of vitamin E In this sense, it is also essential for the ANTIOX group to understand the mechanisms behind stress sensing and signaling by vitamin E.
