  • Descrição: Plants sense environmental signals by various sensory mechanisms distributed over all subcellular compartments. Plasma membrane integrated receptors sense pathogens, excess salinity, hormonal signals and light. Through membrane transporters, soluble environmental signals are imported into the cytosol, where the ion, redox and pH homeostasis is controlled. Endomembranes and microbodies form small cellular sub-compartments involved in environmental sensing and signal transduction. Light sensing, which strongly controls plant metabolism, is separated into qualitative light sensing by photoreceptor proteins at the plasma membrane and in the cytosol and quantitative light sensing through photosynthesis. Embedded into the cytosol, besides light sensing, the organelles mainly integrate environmental signals, respond to cytosolic changes and trigger metabolite fluxes, the energy supply and developmental programmes such as cell death. Covering a selection of environmental sensing mechanisms, recent insights into the diversity of subcellular sites and mechanisms of environmental sensing will be reviewed.
