Researchers discover two redox cascades that regulate chloroplast function and contribute to plant survival

A fundamental challenge of the plant life cycle is how to manage fluctuating environmental conditions. To preserve the integrity and efficiency of photosynthesis, chloroplasts have evolved multiple adaptive strategies to changes in light environments. The thiol-based redox regulation system is important for controlling chloroplast functions in response to light signal. This system has been traditionally considered to be supported only by ferredoxin-thioredoxin reductase (FTR)/thioredoxin (Trx) redox cascade. However, emerging genomics and proteomics data indicate that chloroplasts have a complex redox network, not a simple one-directional cascade.
