Summary Starch, the most abundant storage carbohydrate in plants, has been a major feedstock for first‐generation biofuels. Growing fuel demands require, however, that the starch yields of energy crops be improved. Leaf starch is synthesised during the day and degraded at night to power nonphotosynt...
