“…These parameters indicate that the redox environment was shifted into more reducing directions, which can ensure the appropriate function of many proteins. The involvement of FRL in the activation of AsA-GSH cycle enzymes during the cold acclimation process was shown in wheat, too [ 92 ]. Interestingly, RL increased sensitivity to Cd stress, while BL triggered the opposite effect through increasing the expression and activity of APX, CAT, SOD, and GR, as well as GSH content in cucumbers ( Cucumis sativus L.) [ 93 ].…”

“…This hypothesis was not confirmed in wheat since the reduction in the GSSG/GSH ratio by FRL was not accompanied by changes in the recovery after drought in a drought-tolerant wheat genotype [ 91 ]. Similarly, the growth of wheat seedlings in supplementary FRL also affected the redox state of the glutathione pool during cold treatment, but it did not alter the recovery of the plants compared to their cultivation in WL [ 92 ]. The change in the redox state of the glutathione pool may not derive from the transcriptional regulation of the genes involved in GSH synthesis as observed in wheat and Arabidopsis [ 170 ].…”

Both light intensity and spectrum (280–800 nm) affect photosynthesis and, consequently, the formation of reactive oxygen species (ROS) during photosynthetic electron transport. ROS, together with antioxidants, determine the redox environment in tissues and cells, which in turn has a major role in the adjustment of metabolism to changes in environmental conditions. This process is very important since there are great spatial (latitude, altitude) and temporal (daily, seasonal) changes in light conditions which are accompanied by fluctuations in temperature, water supply, and biotic stresses. The blue and red spectral regimens are decisive in the regulation of metabolism because of the absorption maximums of chlorophylls and the sensitivity of photoreceptors. Based on recent publications, photoreceptor-controlled transcription factors such as ELONGATED HYPOCOTYL5 (HY5) and changes in the cellular redox environment may have a major role in the coordinated fine-tuning of metabolic processes during changes in light conditions. This review gives an overview of the current knowledge of the light-associated redox control of basic metabolic pathways (carbon, nitrogen, amino acid, sulphur, lipid, and nucleic acid metabolism), secondary metabolism (terpenoids, flavonoids, and alkaloids), and related molecular mechanisms. Light condition-related reprogramming of metabolism is the basis for proper growth and development of plants; therefore, its better understanding can contribute to more efficient crop production in the future.

“…Changes in light spectrum and intensity can alter the stress response of plants. For instance, growing wheat seedlings at low R:FR ratios changed the antioxidant enzymes involved in the ASA-GSH cycle's response to cold treatment [182]. The detrimental effects of salt stress were reduced by a low R:FR ratio in tomato since it reduced the levels of H2O2 and malondialdehyde (MDA) [183].…”
