How chloroplasts maintain energy efficiency

All life on earth ultimately relies on energy from the sun, and photosynthesis is the vital link. Photosynthesis generates adenosine triphosphate (ATP), which is the universal molecular fuel in living organisms. An international team of researchers developed an approach to visualize ATP in living plants and observed that mature plant chloroplasts manage their ATP largely in isolation from other cellular spaces. The results pinpoint a strategy of plants to use their energy efficiently that could inform future crop breeding.
