- ROS generation in plants: Boon or bane? (2009, background): “The plant counters this by regulating energy distribution between the light-harvesting complexes and by judicious use of certain carotenoids, which can quench both the triplet chlorophyll state and the 1O2 itself (Holt et al. 2005).”
- The role of the xanthophyll cycle and of lutein in photoprotection of photosystem II. (2012, background): “Although the mechanistic basis of the quenching process in Q2 has not been determined unequivocally, it is possible that the reported formation of Zx – Chl CT states [92] is involved in this type of quenching.”
- Vitamin synthesis in plants: tocopherols and carotenoids. (2006, background): “Carotenoids are involved in photosystem assembly, light harvesting and photoprotection, photomorphogenesis, nonphotochemical quenching, lipid peroxidation and affect the size and function of the light-harvesting antenna and seed set (35, 47, 52, 62, 69, 93).”
- Reactive Species and Antioxidants. Redox Biology Is a Fundamental Theme of Aerobic Life (2006, background): “…1Dg (written just as singlet O2 or 1O2 from now on) is the curse of the illuminated chloroplast; insufficient energy dissipation during photosynthesis can lead to formation of a chlorophyll triplet state that can transfer its excitation energy onto ground-state O2 to make 1O2 (Holt et al., 2005).”
- Phytosequestration: Carbon Biosequestration by Plants and the Prospects of Genetic Engineering (2010, background): “One example is carotenoid quenching of excitation energy through the xanthophyll cycle (Niyogi 1999, Holt et al. 2005).”
- Fast Regulation of Photosynthesis in Diatoms: Mechanisms, Evolution and Ecophysiology (2007, background): “Hence both PsbS and ZX promote and stabilize the switching of the whole LHC antenna into a dissipative mode (in addition to the light-harvesting mode) where excess excitation energy is converted into heat meanwhile Chl fluorescence is quenched (Holt et al. 2005; Pascal et al. 2005).”
- Non-Photochemical Quenching and Energy Dissipation in Plants, Algae and Cyanobacteria (2014, background): “…ultrafast absorption changes, generated upon selective excitation at 664 nm of light-adapted (+qE) and of dark adapted (−qE) spinach thylakoids, Holt et al. (2005) established that the + qE state is associated with the transient appearance of a Z cation radical (Z+.) whose absorbance at 1000…”
- Response of Chlorophyll, Carotenoid and SPAD-502 Measurement to Salinity and Nutrient Stress in Wheat (Triticum aestivum L.) (2017, background): “Being essential structural components of the photosynthetic antenna, Ct participate in harvesting light energy for photosynthesis [14,15].”
- Ultrafast transient absorption spectroscopy: principles and application to photosynthetic systems (2009, background): “Accordingly, this kind of system has been used to study exciton migration in large systems with many connected pigments such as chloroplasts and light-harvesting complex (LHC) II aggregates (Holt et al. 2005; Ma et al. 2003; Ruban et al. 2007).”
- The photoprotective molecular switch in the photosystem II antenna. (2012, neutral): “A xanthophyll radical cation signal with a rise time of ~11 ps, attributed to zeaxanthin, was detected in thylakoids in the qE state upon chlorophyll excitation by Fleming and co-workers using TA spectroscopy [182].”
