Our recent graphical review in Redox Biology highlights oxylipins roles in plastidial retrograde signaling

Chloroplasts are important hubs for the integration of developmental and stress signals in plant cells, but mechanisms related to reception and transmission of these signals are still poorly understood. In this context, the international journal Redox Biology has recently published a graphical review article entitled Oxylipins in plastidial retrograde signaling by our ANTIOX members Dr. Paula Muñoz and Prof. Sergi Munné-Bosch, where they highlight the relevant role of these compounds derived from the oxidation of polyunsaturated fatty acids in plastidial retrograde signaling to highlight future avenues for research.

In the mentioned review, our ANTIOX members emphasize plastid diversity regarding developmental stage, plant organ or stressful conditions, where the production of oxylipins might be affected and become intermediate signals or hormonal elicitors to facilitate acclimation or developmental responses. The review article also describes the latest knowledge related to signal transduction of reactive electrophilic species as secondary lipid peroxidation products which have been long overlooked when describing oxylipin-related signal transduction and the problems associated with the study and interpretation of the production of these molecules in plant cells.
