Function
Mediates tolerance to oxidative stresses (e.g. hydrogen peroxide H(2)O(2), diamide, menadione and tert-butyl hydroperoxide) by minimizing the negative effects of oxidation and monitoring photosynthesis during stress (PubMed:17092320). Promotes root development. Prevents premature aging (e.g. senescence and flowering). Involved in resistance against compatible pathogens such as Botrytis cinerea and Pseudomonas syringae pv. tomato (PubMed:21736589).
