Back to primary endosymbiosis: from plastids to artificial photosynthetic life-forms

Throughout evolution, only two known primary photosynthetic endosymbiosis occurred, which originated the Archaeplastida and the Paulinella spp. Fundamental questions regarding primary endosymbiosis remain unsolved, but may now be addressed with the recent development of chimeric photosynthetic life-form. Cournoyer et al. could establish artificial photosynthetic endosymbiosis between yeast and cyanobacteria.

Automated summary

Only two primary photosynthetic endosymbiosis are known to have occurred throughout evolution, resulting in the formation of Archaeplastida and Paulinella spp. The fundamental questions surrounding primary endosymbiosis remain unanswered, but recent advancements in chimeric photosynthetic life-forms offer new opportunities for studying them. Cournoyer et al. have successfully established artificial photosynthetic endosymbiosis between yeast and cyanobacteria.
