Canopy nitrogen distribution is optimized to prevent photoinhibition throughout the canopy during sun flecks

, 2018
As photoinhibition primarily reduces the photosynthetic light use efficiency at low light, sunfleck-induced photoinhibition might result in a fatal loss of carbon gain in the shade leaves within a canopy with barely positive carbon balance.

Disruption of starch biosynthesis and triacylglycerol degradation impairs growth but improves photosynthesis in Arabidopsis

New Phytologist, Volume 251, Issue 6, Page 3472-3488, September 2026.
Proposed model for altered carbon partitioning in wild‐type (a) and tgd1 sdp1 adg1‐1 Arabidopsis triple mutant (b). Summary Enhancing lipid accumulation by redirecting carbon from starch to triacylglycerol (TAG) in vegetative tissues is a promising strategy for developing high‐energy‐density crops for bioenergy production. However, our understanding of

Photodamage to Oxygen Evolving Complex - An Initial Event in Photoinhibition of Photosystem II. [PDF]

, 2007
Photosystem II (PSII) of oxygenic photosynthesis is susceptible to photoinhibition. Photoinhibition is defined as light induced damage resulting in turnover of the D1 protein subunit of the reaction center of PSII. Both visible and ultraviolet (UV) light

Overexpression of Rubisco Activase Improves Photosynthesis and Plant Growth in Rice Under Fluctuating Light Under Future High CO2 Conditions

Plant, Cell &Environment, Volume 49, Issue 9, Page 6653-6667, September 2026.
ABSTRACT Rubisco activase mediates the activation of Rubisco, the key photosynthetic CO2‐fixing enzyme, and plays a crucial role in regulating photosynthesis and plant growth. Rubisco activase restores catalytic competence to Rubisco active sites by promoting the release of inhibitors in an ATP‐dependent manner.

Photoinhibition and Photoprotection under Environmental Stresses

Abiotic and Biotic Stress Journal, 2015
Plants are often exposed in their habitat to multiple abiotic and biotic stresses (e.g. high light intensity, low or high temperatures, water shortage, salinity, diseases, etc.) that hamper growth and productivity; however plants are able, to some extent, to cope with limiting environmental conditions by means of different mechanisms that contribute to

Data_Sheet_1_Growth Light Environment Changes the Sensitivity of Photosystem I Photoinhibition Depending on Common Wheat Cultivars.pdf

, 2019
Light is an important factor for determining photosynthetic performance in land plants. At high light intensity, land plants develop photosynthetic activity by increasing electron sinks, such as the Calvin cycle and photorespiration and photoprotective ...

Changes in Foliar Water Uptake Caused by Water Stress in Cattleya Lindl. (Orchidaceae)

Physiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT In response to water restrictions imposed by the epiphytic environment, orchids have developed strategies to increase water‐use efficiency, such as the expression of Crassulacean Acid Metabolism (CAM) and the foliar water uptake (FWU). In a climate change scenario, FWU may emerge as a strategy to reduce water stress during drought.

Impact of the Simultaneous Loss of the Plastid Envelope‐Localized Homologous Pair Ycf10 and DLDG1 in Plant Growth and Photosynthetic Performance

Physiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Ycf10 and DLDG1 are homologous proteins embedded in the chloroplast envelope membranes (EM) and encoded in the plastidial and nuclear genomes, respectively. We previously characterized Arabidopsis dldg1 and tobacco ycf10 mutants, and showed that these proteins mediate proton transport across the EM, thereby influencing ATP synthesis and the ...

Genome Manipulation in Microalgae: A Systematic Map on Improved Traits, Strains, and Their Commercial Applications

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Microalgae are promising platforms for producing diverse biocompounds relevant to multiple commercial sectors, and the use of genomic technologies in microalgae is rapidly expanding. To examine the research trends, we conducted a bibliographic analysis (systematic map) of this rapidly developing field. Our study presents a descriptive overview
