How #plants adjust their #photosynthesis to changing #light.
Photosynthesis is the central process by which plants build up biomass using light, water, and carbon dioxide from the air. Gaining a detailed understanding of this process makes it possible to modify and thus optimize it—for example, with a view to increasing food production or stress tolerance.

The oldest evidence of photosynthetic structures reported to date has been identified inside a collection of 1.75-billion-year-old microfossils, a Nature paper reveals. The discovery helps to shed light on the evolution of oxygenic photosynthesis.

The cells of living organisms are equipped with proteins that are involved in the shaping and remodeling of cellular membranes, thereby performing important tasks. The cell membrane encloses the cell interior, but is constantly remodeled, for example, due to membrane budding, invagination, or fusion processes. This also involves various proteins that were long assumed to be present exclusively or predominantly in higher organisms.
