Water use efficiency in cereal crops is governed by molecular processes operating across biological scales that are connected imperfectly and non-linearly, from guard cell ion channel gating to canopy evapotranspiration. Despite the global ...
Diazotrophy affects the state transitions in unicellular nitrogen fixing cyanobacteria [0.03%]
固氮作用影响单细胞固氮蓝藻的光适应状态转换现象

A new type of kinetic chlorophyll fluorometer (Klughammer et al. 2024, Photosynth Res 161:151-176) which enables measuring the changes of rel. fluorescence yield during application of saturating single-turnover 15µs flashes (ST-kinetics, S...
Improved state‑transition analysis in tobacco lines differing in isoprene emission via spectral‑retrieval separation of PSI and PSII fluorescence at physiological temperature [0.03%]

Lorenzo Palombi et al.
State transition (ST) is a key regulatory mechanism that balances excitation energy between photosystem II (PSII) and photosystem I (PSI). Although its general principles have been known for decades, methodological constraints have limited ...

Due to fluctuations in sunlight intensity, balancing light-harvesting efficiency and photoprotection is critical for plant fitness. To achieve this balance, plants have evolved a highly regulated mechanism, non-photochemical quenching (NPQ)...
Photoprotection in a desert moss: dynamic excitation quenching during the hydration cycle of the Syntrichia caninervis [0.03%]

Desiccation-tolerant mosses survive extreme water loss by activating efficient photoprotective mechanisms that prevent damage to the photosynthetic apparatus. The most resistant moss Syntrichia caninervis (S. caninervis) represents an impor...
Energy quenching via triplet-excited state formation of glycosylated carotenoids in the photosynthetic reaction center complex of the green sulfur bacterium Chlorobaculum tepidum [0.03%]
绿硫细菌氯杆菌属温热菌株 photosynthetic reaction center 复合物中糖基类胡萝卜素通过三重态淬灭能量的作用机制研究
Tomomi Inagaki,Masatoshi Kida,Daisuke Kosumi et al.
Tomomi Inagaki et al.
Some carotenoids have a function to quench excitation energy of chlorophyll in photosynthetic apparatuses. This is a part of the photoprotective mechanism, non-photochemical quenching (NPQ), which prevents the inhibitory effects of high-lig...
Quantitative phosphoproteomics profiling reveals the regulatory mechanisms underlying high light stress in maize and rice [0.03%]
定量磷酸蛋白质谱分析揭示了高光胁迫下玉米和水稻的调控机制

Yanmei Chen et al.
High light stress seriously compromises crop yields and food security. Protein phosphorylation plays a key regulatory role in high light responses; however, their complexity hinders a full understanding of these processes. To address this, ...
Siphonous green macroalgae with contrasting capacities for the energy-dependent quenching, qE, rely on different photoprotective mechanisms [0.03%]
具有不同能量依赖型淬灭机制的大型绿藻依靠不同的光保护机制
Heta Mattila,Vesa Havurinne,Paulo Cartaxana et al.
Heta Mattila et al.
Bryopsidales green macroalgae can induce non-photochemical quenching (NPQ) only slowly, presumably due to the lack of the proton gradient-induced component (qE) of NPQ and xanthophyll cycle. Here, two morphologically rather similar siphonou...
