Distinctive features of photosynthetic carbon metabolism in secondary endosymbiotic algae
Tsuji, Yoshinori; Shiraiwa, Yoshihiro
Abstract Current knowledge of photosynthetic carbon metabolism has primarily been documented through studies of green algae and higher plants, which have evolved through primary endosymbiotic lineages originating from cyanobacteria. Secondary endosymbiotic lineages, on the other hand, have evolved through the process of engulfment of primary endosymbiotic red or green algae by non-photosynthetic eukaryotes. Recent studies have reported distinct features of photosynthetic carbon metabolism in secondary endosymbiotic algae compared to that in primary symbiotic algae. The present study focuses on recent advances in the characterization of photosynthetic primary carbon metabolism in secondary endosymbiotic algae, such as coccolithophores and diatoms.
