Abstract

Changes in environmental conditions such as light intensity or temperature result in an imbalance between the light energy absorbed throughphotochemistry versus the energy utilized through metabolism. Such anenergy imbalance is sensed through alterations in photosystem II excitation pressure, which reflects the relative reduction state of the photosystem. Modulation of this novel, chloroplastic redox signal eitherby excess light or by low temperature initiates a signal transductionpathway. This appears to coordinate photosynthesis-related gene expression and to influence the nuclear expression of a specific cold-acclimation gene, plant morphology and differentiation in cyanobacteria. Thus, in addition to its traditional role in energy transduction, the photosynthetic apparatus might also be an environmental sensor.
