Mapping the redox regulatory landscape: a bit of history and a look to the future

Redox exchanges are the beating heart of plant growth. Through photosynthetic and respiratory electron transfer, as well as numerous other oxidoreduction processes, plants generate reducing compounds and energy essential to their development and survival. Thus, it is hardly surprising that systems have evolved to control and monitor the status of key redox components, and to use this information as an indicator of environmental conditions. Such information is crucial in plant adaptation and acclimation to ongoing modifications in atmospheric composition and associated changes in climate, which are predicted to exacerbate the intensity of stress conditions.
