Desiccation and stress responses

Main research interests

Redox signaling mechanisms are known to be implicated in plant adaptation to environmental conditions and stress. One of the main actors involved in the regulation of the cellular redox state is a multigenic family of ubiquitous oxidoreductases named thioredoxins (TRXs). The team is expert on plastidial TRXs and has characterized the functional relationships between TRXs and numerous TRX targets. We have studied the expression profiles of A. thaliana TRXs showing that a specific class of plastidial TRXs is expressed in non-photosynthetic organs, including seeds. Our recent findings underscore the physiological importance of some TRXs and their targets in plant responses to environmental stresses.
