Global Change Biology Communications, Volume 1, Issue 2, June 2026.Conceptual framework linking leaf‐level photorespiratory biochemistry to global‐scale uncertainty in carbon cycle modelling. Rubisco acts as a temperature‐sensitive biochemical switch: At optimal temperatures (~25°C) carboxylation dominates and drives biomass accumulation, whereas heat stress (> 35°C) favours oxygenation and initiates photorespiration (

How does cyclic electron flow alleviate photoinhibition in Arabidopsis?
, 2009 Cyclic electron flow (CEF) around photosystem I has a role in avoiding photoinhibition of photosystem II (PSII), which occurs under conditions in which the rate of photodamage to PSII exceeds the rate of its repair.

Plant-Environment Interactions, Volume 7, Issue 3, June 2026.ABSTRACT This study investigated the growth and leaf metabolism of clonal cocoa varieties in response to field stress conditions during wet and dry seasons. It was hypothesized that clonal cocoa varieties differ in their growth, photochemical efficiency, relative water content and central carbon metabolism under seasonal field stress conditions ...

Cell Reports, 2016 The ventral tegmental area (VTA) receives phenotypically distinct innervations from the pedunculopontine tegmental nucleus (PPTg). While PPTg-to-VTA inputs are thought to play a critical role in stimulus-reward learning, direct evidence linking PPTg-to ...

Enhancing the Transparency–Temperature Trade‐Off Through Spectral Engineering and Radiative Cooling
Small Science, Volume 6, Issue 6, June 2026.This study presents a scalable multilayer greenhouse film for radiative cooling that balances photosynthetically active radiation and cooling performance through spectral engineering via combining TiO2–polyethylene terephthalate scattering with ultraviolet–IR selective layers.

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

Shrubs inhibit plant diseases by intercepting light in alpine meadows
Functional Ecology, Volume 40, Issue 6, Page 1644-1655, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change is disproportionately impacting mountain ecosystems, leading to widespread shrub expansion into alpine meadows. Shrub encroachment alters the albedo, carbon budget and warming rate in alpine grasslands, but it remains challenging to predict how shrub ...
