High-resolution structure of the heat-stable form-IAq RuBisCO from the thermophilic purple sulfur bacterium Thermochromatium tepidum

Scientific Reports
Ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO) catalyzes the initial carbon fixation reaction in the Calvin-Benson-Bassham cycle. Among the many forms of RuBisCOs, form-I—a protein complex containing 8 large and 8 small subunits—is the most ...

Biochar and K‐fertigation modulate stomatal behaviour, ion homeostasis and water use efficiency in waxy maize seedlings under salt stress

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
Efficacy of wheat straw biochar in alleviating salt stress under K‐fertigation via improved photosynthesis, water use efficiency and ion homeostasis in waxy maize. ABSTRACT K‐fertigation and soil amendment could ameliorate the adverse effects of saline stress on C4 crop physiology and performance, yet the underlying mechanisms remained largely elusive.

Rubisco activase activity assays

, 2010
Ribulose-1,5-bisphosphate (RuBP) carboxylase/oxygenase (Rubisco) activase functions as a mechano-chemical motor protein using the energy from ATP hydrolysis to contort the structure of its target protein, Rubisco.

Growth Temperature Alters the Thermal Sensitivity of Mesophyll Conductance in Wild and Cultivated Tomato

Plant, Cell &Environment, Volume 49, Issue 11, Page 7946-7956, November 2026.
ABSTRACT Mesophyll conductance (gm) is a key component of internal CO2 diffusion and can limit photosynthesis in C3 leaves. Temperature responses of gm are commonly treated as intrinsic properties of the leaf, yet it remains unclear whether they acclimate to growth conditions. Here, we tested whether growth temperature alters the thermal sensitivity of

Daily Heat Stress Induces Donor‐Side Limitation of PSI Via Downregulation of the Cyt b6f Complex

Plant, Cell &Environment, Volume 49, Issue 11, Page 8099-8111, November 2026.
ABSTRACT The rapidly warming climate is driving increasingly frequent and intense heat waves worldwide, posing major challenges to plant metabolism and growth. Despite the central role of photosynthesis in plant growth, the effects of prolonged heat stress on the primary reactions of photosynthesis remain poorly understood.

Design Principles of Plant Thermotolerance: Integrating Photosynthesis, Reproduction, and Field Resilience in a Warming Climate

Plant, Cell &Environment, Volume 49, Issue 11, Page 8735-8750, November 2026.
ABSTRACT Global food security is increasingly threatened by climate change, as rising temperatures compromise the yields of major staple crops, including wheat, rice, and maize. Enhancing plant thermotolerance has therefore become a critical priority for sustaining agricultural productivity.
