AbstractHigher plant photosystem II (PS II) generates superoxide anion radicals (O(2)((center dot) over bar)) under strong illumination, in which the O(2)((center dot) over bar) plays a pivotal role in reactive oxygen species (ROS) metabolism during higher plant photosynthesis. The photosystem of Chlamydomonas reinhardtii Is highly similar to that of higher plants. The generation of O(2)((center dot) over bar) in C. reinhardtii thylakoid membranes and PS R particles has been firstly proved by means of spin trapping-ESR technique and NBT-mediated spectral assay. Referring to the spin trapping-ESR evidences in spinach, the mechanisms of O(2)((center dot) over bar) generation both in C. reinhardtii and spinach look identical. Compared to higher plant, C. reinhardtii has several irreplaceable advantages: simpler structure; clearer genetic background and genomic sequencing has been finished; easy to introduce mutations in photosystem. As a result, the study concerning the O(2)((center dot) over bar) generation in C. reinhardtii introduces a new promising model for further investigation of ROS metabolism in higher plant photosynthesis.
