On the Cover

Reactive oxygen species (ROS) are molecules generated by the metabolism of mitochondria, peroxisomes, chloroplasts, endoplasmic reticulum, glyoxysomes, and apoplast. The plant cell takes advantage of ROS to send signals and to induce changes in the nucleus (i.e., retrograde). The signal can be carried out directly by ROS or indirectly as a consequence of membrane lipids oxidation. The physiological role of retrograde signal is to alert the nucleus about the development and physiological status of the different organelles.
