AB  - Plants are inevitably exposed to extreme climatic conditions that lead to a disturbed balance
between the amount of absorbed energy and their ability to process it. Variegated leaves with
photosynthetically active green leaf tissue (GL) and photosynthetically inactive white leaf tissue
(WL) are an excellent model system to study source–sink interactions within the same leaf under the
same microenvironmental conditions. We demonstrated that under excess excitation energy (EEE)
conditions (high irradiance and lower temperature), regulated metabolic reprogramming in both
leaf tissues allowed an increased consumption of reducing equivalents, as evidenced by preserved
maximum efficiency of photosystem II (φPSII) at the end of the experiment. GL of the EEE-treated
plants employed two strategies: (i) the accumulation of flavonoid glycosides, especially cyanidin
glycosides, as an alternative electron sink, and (ii) cell wall stiffening by cellulose, pectin, and lignin
accumulation. On the other hand, WL increased the amount of free amino acids, mainly arginine,
asparagine, branched-chain and aromatic amino acids, as well as kaempferol and quercetin glycosides.
Thus, WL acts as an important energy escape valve that is required in order to maintain the successful
performance of the GL sectors under EEE conditions. Finally, this role could be an adaptive value of
variegation, as no consistent conclusions about its ecological benefits have been proposed so far.
