ABSTRACT

Reactive oxygen species are produced metabolically when excessive energy input exceeds the reducing potential. It is now widely recognized that plants adopted fluctuating perturbations in hydrogen peroxide (H2O2) homeostasis as a first line alerting and signaling system to adjust organellar and cellular metabolism during stress conditions. Unfortunately, our understanding of the signaling network that governs H2O2 sensing, transduction and eventually trigger transcriptional response remains fragmentary. Earlier transcriptomic and genomic-centered studies, provided us first with extra insights in the regulatory networks that govern the oxidative stress response. Recently, tailoring various proteomics technologies allowed us to assess oxidative stress dependent changes at the posttranslational level. Through combined multi-omics efforts, we aim towards a better understanding of how cells interpret the oxidative signals that arise from developmental cues and stress conditions.
