- Аннотация: The significance of the spectral composition of light for growth and other physiologicalfunctions of plants moved to the focus of “plant science” soon after the discovery of photosynthesis,if not earlier. The research in this field recently intensified due to the explosive development ofcomputer-controlled systems for artificial illumination and documenting photosynthetic activity.The progress is also substantiated by recent insights into the molecular mechanisms of photo-regulationof assorted physiological functions in plants mediated by photoreceptors and other pigment systems.The spectral balance of solar radiation can vary significantly, affecting the functioning and developmentof plants. Its effects are evident on the macroscale (e.g., in individual plants growing under theforest canopy) as well as on the meso- or microscale (e.g., mutual shading of leaf cell layers andchloroplasts). The diversity of the observable effects of light spectrum variation arises through (i)the triggering of different photoreceptors, (ii) the non-uniform efficiency of spectral components indriving photosynthesis, and (iii) a variable depth of penetration of spectral components into the leaf.We depict the effects of these factors using the spectral dependence of chloroplast photorelocationmovements interlinked with the changes in light penetration into (light capture by) the leaf and thephotosynthetic capacity. In this review, we unfold the history of the research on the photocontroleffects and put it in the broader context of photosynthesis efficiency and photoprotection under stresscaused by a high intensity of light.
