Absorption of Energy in Excess, Photoinhibition, Transpiration, and Foliar Heat Emission Feedback Loops During Global Warming [PDF]

Cells
Global warming is increasingly constraining plant productivity by altering the photosynthetic energy balance and leaf thermoregulation. Under high light and elevated temperatures, absorption of energy in excess (AEE) by photosystem II disrupts ...

The combined effect of Cd and high light stress on the photochemical processes in Arabidopsis thaliana [PDF]

Photosynthetica
The adverse effects of cadmium on plants are accompanied by a limitation of photosynthesis, due to the production of reactive oxygen species, leading to oxidative damage to PSII and the disruption of key protein complexes involved in photosynthetic ...

Moderate Shading Improves Growth, Photosynthesis, and Physiological Traits in Spuriopinella brachycarpa (Kom.) Kitag. [PDF]

Plants
To investigate the effects of varying degrees of shading on the photosynthetic characteristics of Spuriopinnella brachycarpa (Kom.) Kitag. experiments were conducted under five shading treatments: 0% (full sunlight), 20%, 40%, 60%, and 80%.

Differences in susceptibility to photoinhibition do not determinegrowth rate under moderate light in batch or turbidostat - a studywith five green algae

Photosynthetica, 2022
To understand growth limitations of photosynthetic microorganisms, and to investigate whether batch growth or certain photosynthesis-related parameters predict a turbidostat (continuous growth at constant biomass concentration) growth rate, five green ...

PSI Photoinhibition and Changing CO₂ Levels Initiate Retrograde Signals to Modify Nuclear Gene Expression

Antioxidants, 2023
Photosystem I (PSI) is a critical component of the photosynthetic machinery in plants. Under conditions of environmental stress, PSI becomes photoinhibited, leading to a redox imbalance in the chloroplast.

Dissecting photosynthetic electron transport and photosystems performance in Jerusalem artichoke (Helianthus tuberosus L.) under salt stress

Frontiers in Plant Science, 2022
Jerusalem artichoke (Helianthus tuberosus L.), a vegetable with medical applications, has a strong adaptability to marginal barren land, but the suitability as planting material in saline land remains to be evaluated.

Photoinhibition of Photosystem I Induced by Different Intensities of Fluctuating Light Is Determined by the Kinetics of ∆pH Formation Rather Than Linear Electron Flow

Antioxidants, 2022
Fluctuating light (FL) can cause the selective photoinhibition of photosystem I (PSI) in angiosperms. In nature, leaves usually experience FL conditions with the same low light and different high light intensities, but the effects of different FL ...

Regulation of Leaf Angle Protects Photosystem I under Fluctuating Light in Tobacco Young Leaves

Cells, 2022
Fluctuating light is a typical light condition in nature and can cause selective photodamage to photosystem I (PSI). The sensitivity of PSI to fluctuating light is influenced by the amplitude of low/high light intensity.

Special issue in honour of Prof. Reto J. Strasser - Photoinhibition of oxygen-evolving complex and photosystem II at chilling stress in the tropical tree species Dalbergia odorifera

Photosynthetica, 2020
Photosystem II is sensitive to chilling stress in tropical tree species. However, the underlying mechanism is not clear. In this study, we examined the effects of chilling and light stress on activities of PSII and oxygen-evolving complex (OEC), in order
