Here, we describe some recent insights into how ROIs and RNIs are synthesized and how these small, redox active molecules help orchestrate the plant defence response.
The reviewed data highlights the growing importance of ROIs and RNIs in orchestrating the development of plant immunity and provides insights into the molecular mechanisms underpinning their function.
Signalling via small, redox active molecules is a key feature underpinning a diverse series of signal transduction networks in eukaryotic cells. Therefore, insights into the mechanisms that support the activity of these molecules may have potentially wide significance.
