Photosynthetic Processes and Mechanisms

Specialisation of photosynthetic biochemistry in C4 chloroplasts potentiates distinct cell-specific functionality of different chloroplast-to-nucleus retrograde signalling pathways.

The paper shows that chloroplast-to-nucleus retrograde signalling pathways are cell-specific in C4 plants, correlating with photosynthetic specialisation in mesophyll and bundle sheath cells.
