Reverse engineering of plant photosynthesis in harmonically modulated light

Popis výsledku v původním jazyce

Plant photosynthesis is performed by a complex, strongly regulated system with light serving as an energetic input and, indirectly, as a dominant regulatory signal. Harm. modulated light of a long period (typically tens of seconds) as an input that is expected to yield output signals highly sensitive to relatively slow regulatory processes. In the accompanying, we show that the harmonically modulated light elicits a highly non-linear fluorescence response with resonances appearing at characteristic frequencies and with strong upper harmonic modes.The light activation of ATP-ase or the activation of RUBISCO are known examples of positive feedback mechanisms where as the non-photochemical quenching or state transitions represent, in photosynthesis, the negative feedback regulation. In the present paper, we explore math. models assuming that the observed complex non-linear response of plants to harmonic forcing reflects a generalized feedback regulation by a sensor component.
