Concurrent Temperature and Light Intensity Fluctuations Promote Stomatal Opening and Non‐Steady State Photosynthesis

Plant, Cell &Environment, Volume 49, Issue 8, Page 5005-5021, August 2026.
ABSTRACT In nature, fluctuations in light intensity (FL) are tightly coupled to rapid changes in leaf temperature (Tleaf), yet the short‐term physiological effects of these concurrent drivers remain largely unresolved. Here, we combined rapid infrared induced Tleaf fluctuations with controlled step changes in light intensity for leaf gas exchange ...

Genomic and Physiological Insights Into Heat–Drought Tolerance in Wheat Through GWAS and Phenotypic Evaluation

Plant, Cell &Environment, Volume 49, Issue 8, Page 5511-5529, August 2026.
ABSTRACT Climate change‐driven heat and drought stresses during reproductive stages significantly threaten wheat productivity. To investigate the genetic and physiological basis of combined heat–drought (HD) tolerance, we evaluated 345 wheat genotypes under three environments of HD stresses, non‐stress glasshouse conditions and a late‐sowing field ...

A characterisation of Rubisco activase from Spinacia oleracea [PDF]

, 2014
Rubisco activase undergoes ATP hydrolysis to activate Rubisco which has generated an inhibitor. Recent crystallographic evidence has proposed several models however the correct model is disputed.

Temperature Acclimation of Chlorophyll Fluorescence and Carboxylation Capacity From Near‐Instantaneous to Weekly Time Scales

Plant, Cell &Environment, Volume 49, Issue 8, Page 5497-5510, August 2026.
ABSTRACT We studied near‐instantaneous temperature responses of light‐saturated photosynthesis (Asat) and the operating efficiency of photosystem II (ΦPSII) in relation to acclimation of photosynthetic biochemistry to temperature at the timescale of 1–8 days. We grew two closely related Brassica oleracea L.

The Multi‐Omics Opportunity to Improve Heat Adaptation in Chickpea

Food and Energy Security, Volume 15, Issue 4, July/August 2026.
ABSTRACT Heat stress during reproductive development is a critical constraint to chickpea (Cicer arietinum L.) productivity in major growing regions, where high temperatures cause yield losses through flower and pod abortion, reduced pollen viability and impaired grain filling.

Effects of the Terminal Regions on Rubisco Activase Form and Function [PDF]

, 2017
Rubisco is the sole enzyme responsible for the incorporation of CO2 into sugar molecules useable by all life on earth. In the vast majority of discovered autotrophic organisms their respective rubisco has been accompanied by another enzyme called ...

Molecular adaptation during adaptive radiation in the Hawaiian endemic genus Schiedea.

PLoS ONE, 2006
Background"Explosive" adaptive radiations on islands remain one of the most puzzling evolutionary phenomena. The rate of phenotypic and ecological adaptations is extremely fast during such events, suggesting that many genes may be under fairly strong ...

CIA5 and its interacting metal‐binding GTPase ZNG3 are degraded by the proteasome in Zn deficiency

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY Carbon and zinc (Zn) metabolism are tightly connected in phototrophs, as carbonic anhydrases critical for CO2 assimilation are highly abundant Zn enzymes. The eukaryotic green alga Chlamydomonas (Chlamydomonas reinhardtii) maintains efficient phototrophic growth in ambient or low CO2 environments by establishing a carbon concentrating mechanism

Lysine acetylome profiling uncovers novel histone deacetylase substrate proteins in Arabidopsis

Molecular Systems Biology, 2017
Histone deacetylases have central functions in regulating stress defenses and development in plants. However, the knowledge about the deacetylase functions is largely limited to histones, although these enzymes were found in diverse subcellular ...

Enhanced CO2 Response and Aging‐Related Dynamics Drive a Greater Leaf Area Index Increase in China's Planted Forests in Comparison to Natural Forests

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract China's forests have experienced a notable increase in leaf area, driven by planted forest expansion and natural forest conservation. However, how planted and natural forests respond differently to environmental changes remains unclear. Using leaf area index (LAI) data, propensity score matching (PSM), and machine learning, we compared these ...
