The MdVQ22‐MdWRKY33d complex regulates MdPER55 and MdDREB1D expression to modulate apple salt tolerance by reactive oxygen species scavenging

The Plant Journal, Volume 128, Issue 2, October 2026.
Significance Statement Apple (Malus domestica) is one of the most extensively cultivated fruit trees worldwide, playing a crucial role in agricultural economies. However, soil salinization remains a significant challenge that severely restricts apple production, especially in regions affected by secondary salinization.

The cost of photoinhibition

, 2011
Photoinhibition is an inevitable consequence of oxygenic photosynthesis. However, the concept of a 'photoinhibition-proof' plant in which photosystem II (PSII) is immune to photodamage is useful as a benchmark for considering the performances of plants ...

Dysfunction of Chloroplast Protease Activity Mitigates pgr5 Phenotype in the Green Algae Chlamydomonas reinhardtii

Plants
Researchers have described protection mechanisms against the photoinhibition of photosystems under strong-light stress. Cyclic Electron Flow (CEF) mitigates electron acceptor-side limitation, and thus contributes to Photosystem I (PSI) protection ...

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.

Does photoinhibition and/or phosphorylation of photosystem II influence its in vivo oligomeric state?

, 1999
We have examined the effects of phosphorylation and photoinhibition upon grana membranes and photosystem II (PSII) by electron microscopy and single particle analysis.

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

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%.

Light Signaling-dependent Regulation of Photoinhibition and Photoprotection in Tomato

, 2017
Photoreceptor-mediated light signaling plays a critical role in plant growth, development, and stress responses but its contribution to the spatial regulation of photoinhibition and photoprotection within the canopy remains unclear.

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

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 ...

The phenomenon of photoinhibition of photosynthesis and its importance in reforestation

, 2015
Photoinhibition, defined as the inhibition of photosynthesis caused by excessive radiance, affects field production to a great extent. This phenomenon is particularly relevant in reforestation practices, when one deals with forests of rapid growth such ...
