Canopy-Level Photochemical Reflectance Index from Hyperspectral Remote Sensing and Leaf-Level Non-Photochemical Quenching as Early Indicators of Water Stress in Maize

Remote Sensing, 2017
In this study, we evaluated the effectiveness of photochemical reflectance index (PRI) and non-photochemical quenching (NPQ) for assessing water stress in maize for the purpose of developing remote sensing techniques for monitoring water deficits in ...

Identifying the gene responsible for non-photochemical quenching reversal in Phaeodactylum tricornutum. [PDF]

Plant J
SUMMARYAlgae such as diatoms and haptophytes have distinct photosynthetic pigments from plants, including a novel set of carotenoids. This includes a primary xanthophyll cycle comprised of diadinoxanthin and its de‐epoxidation product diatoxanthin that enables the switch between light harvesting and non‐photochemical quenching (NPQ)‐mediated ...

Potassium deficiency impairs photosynthetic induction via disrupted electron transport and photochemistry in <i>Phaseolus vulgaris</i>. [PDF]

Front Plant Sci
Our previous study revealed that potassium (K) deficiency depressed carbon assimilation during photosynthetic induction in Phaseolus vulgaris. Building on this work, the current study presents a re-analysis of previously collected gas exchange and ...

Increased biomass productivity in green algae by tuning non-photochemical quenching.

Sci Rep, 2016
Photosynthetic microalgae have a high potential for the production of biofuels and highly valued metabolites. However, their current industrial exploitation is limited by a productivity in photobioreactors that is low compared to potential productivity.

Resistance of Primary Photosynthesis to Photoinhibition in Antarctic Lichen Xanthoria elegans: Photoprotective Mechanisms Activated during a Short Period of High Light Stress

Plants, 2023
The Antarctic lichen, Xanthoria elegans, in its hydrated state has several physiological mechanisms to cope with high light effects on the photosynthetic processes of its photobionts.

The effects of increasing salinity levels on Sulla carnosa photosynthesis are mainly of stomatal nature

Journal of Oasis Agriculture and Sustainable Development, 2023
Sulla carnosa Desf. plants were subjected to 0, 100, 200, and 300 mM NaCl for 40 days. Leaf and stem growth as well as root and leaf water contents were not affected even at 300 mM NaCl, confirming the halophytic nature of this species.

Dehydroascorbate Reductase Affects Non-photochemical Quenching and Photosynthetic Performance [PDF]

Journal of Biological Chemistry, 2008
Ascorbic acid (Asc) is a major antioxidant involved in photoprotection and photosynthetic function in plants. Dehydroascorbate reductase (DHAR) catalyzes the regeneration of Asc from its oxidized state and serves as an important regulator of Asc recycling.
