Abstrakt: In the course of their life, plants continuously experience a wide range of unfavourable environmental conditions in the form of biotic and abiotic stress factors. The perception of stress via various organelles and rapid, tailored cellular responses are essential for the establishment of plant stress resilience. Mitochondria as the biosynthetic sites of energy equivalents in the form of ATP-provided in order to enable a multitude of biological processes in the cell-are often directly impacted by external stress factors. At the same time, mitochondrial function may fluctuate to a tolerable extent without the need to activate downstream retrograde signalling cascades for stress adaptation. In this Focus Review, we summarise the current state of knowledge on the perception and processing of stress signals by mitochondria and show which layers of retrograde signalling, that is, those involving transcription factors, metabolites, but also enzymes with moonlighting functions, enable communication with the nucleus. Also, light is shed on signal integration between mitochondria and chloroplasts as part of retrograde signalling. With this Focus Review, we aim to show ways in which organelle-specific communication can be further researched and the collected data used in the long-term to strengthen plant resilience in the context of climate change.
