DOI: 10.1007/s11120-018-0485-0
Abstract: The cytochrome b6f complex of oxygenic photosynthesis produces substantial levels of reactive oxygen species (ROS). It has been observed that the ROS production rate by b6f is 10–20 fold higher than that observed for the… read more here.

DOI: 10.1042/bcj20220124
Abstract: In oxygenic photosynthesis, the cytochrome b6f (cytb6f) complex links the linear electron transfer (LET) reactions occurring at photosystems I and II and generates a transmembrane proton gradient via the Q-cycle. In addition to this central… read more here.

DOI: 10.1093/plphys/kiad185
Abstract: Photosynthetic organisms frequently experience abiotic stress that restricts their growth and development. Under such circumstances, most absorbed solar energy cannot be used for CO2 fixation and can cause the photoproduction of reactive oxygen species (ROS)… read more here.

DOI: 10.1126/sciadv.add9688
Abstract: Plants use solar energy to power cellular metabolism. The oxidation of plastoquinol and reduction of plastocyanin by cytochrome b6f (Cyt b6f) is known as one of the key steps of photosynthesis, but the catalytic mechanism… read more here.
