Integration of light and plastid signals.

Light and plastid signals promote chloroplast biogenesis and are among the most potent inducers and repressors of photosynthesis-related gene expression, respectively. These signals can be likened to a 'gas and brake system' that promotes efficient chloroplast biogenesis and function. Recent findings indicate that a particular plastid signal can 'rewire' a light signaling network, converting it from an inducer into a repressor of particular photosynthesis-related genes. Therefore, a plastid signal appears to be an endogenous regulator of light signaling rather than a signal acting independently from light. This integration of light and plastid signals may allow plants to proactively manage chloroplast dysfunction when performing chloroplast biogenesis and maintenance in adverse light conditions.
