Maruyama Lab
Machine-translated · View original
A lab exploring the origins and diversity of symbiosis involving photosynthetic organisms.

AboutAbout the lab
Tracing the origins of symbiosis.
The Maruyama Lab studies photosymbiosis, in which photosynthetic organisms live together with other organisms.
As in the case of corals and their symbiotic algae (Symbiodiniaceae, or zooxanthellae), symbiosis can give rise to new ways of living, and plant chloroplasts are thought to be one such example.
The lab approaches its research from two directions: elucidating how symbiosis began, and understanding the diversity of symbioses that are occurring today.
Key terms
- Zooxanthellae (Symbiodiniaceae)
- Small algae (zooxanthellae) that live inside the cells of corals and sea anemones. They pass nutrients made by photosynthesis to their host.
- Chloroplast
- A small organelle in the cells of plants and algae where photosynthesis takes place. It is thought to have originally been a separate organism.
- Photosymbiosis
- Photosymbiosis: a symbiosis in which a photosynthetic organism lives together with another organism, giving rise to a new way of living.
ResearchResearch themes
Almost all organisms on Earth live in symbiosis with other organisms. The lab investigates the mechanisms of symbiosis involving photosynthetic organisms, from the perspectives of gene function and cellular function, in order to shed light on biodiversity and the history of evolution.
*Illustrative imageOrigin and evolution of chloroplasts
Chloroplasts are thought to have originated when an ancestral organism took a photosynthetic bacterium into its cell. By studying the feeding apparatus of bacteria-eating algae and the light-harvesting apparatus, the lab aims to clarify how the first chloroplasts evolved.
*Illustrative imageEvolution and diversity of coral–Symbiodiniaceae symbiosis
Some corals and sea anemones grow using nutrients produced by symbiotic algae (zooxanthellae) living inside their cells. Using the sea anemone Exaiptasia (Aiptasia) and Symbiodiniaceae, the lab investigates the genes and cellular processes involved in the maintenance and breakdown of symbiosis.
