"2022 August 27, Michael Le Page, Genetic tweaking increases soy yield by upgrading photosynthesis, New Scientist, Issue 3401, page 16, When a leaf is in full sunshine, it absorbs more light energy than its photosynthetic machinery can handle. This damages cells unless they turn on a mechanism known as quenching to dissipate the excess energy. When a leaf is shaded, however, quenching has to be turned off to avoid dissipating energy that could be used."
