Using thale cress, a small flowering plant, they showed that altering a particular gene could change the speed with which chloroplasts transform into other structures in plant cells, including those involved in the ripening of fruit.
The researchers' starting point was the calcium pump located in the cell membrane of the model plant thale cress (Arabidopsis thaliana), but the regulatory mechanism also applies to the corresponding calcium pump in humans and animals.
