Photosynthesis in the dark? Unraveling the mystery of algae evolution

A recent study by Waseda University researchers indicated that the effect of respiration on photosynthesis in the glaucophyte Cyanophora paradoxa is surprisingly similar to the interaction between respiration and photosynthesis in cyanobacteria. These results suggest that cyanelles retain many of the characteristics observed in their ancestral cyanobacteria.

“From the view point of metabolic interactions, C. paradoxa is the primary symbiotic algae most similar to cyanobacteria,” says Kintake Sonoike, a professor of plant and cell physiology at Waseda University. “Our findings provide valuable information for revealing how photosynthetic organisms evolved.”

This research is published in Scientific Reports.
