How plants adjust their photosynthesis to changing light

How plants adjust their photosynthesis to changing light

Recent research reveals more details about how plants quickly up- or down-regulate photosythesis based on brightness levels.

Plants live in often rapidly changing light conditions. To make optimum use of this light, the modules must be closely synchronised. There has been little scientific research into this synchronisation in particular to date.
If it is too bright, the plant cannot convert all the light energy; this is a potentially harmful situation. To ensure that no damage is caused by the excess light energy -- which can result in the formation of e.g. highly reactive oxygen species -- the plant activates a protective mechanism: The so-called energy-dependent quenching (for short: "qE") ensures that excess energy is discharged in the form of heat.
