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

open access: yesPlant, 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.

First‐Principles Investigation of the Structural, Electronic, Optical, Elastic, and Thermal Properties of Defect Diamond‐Like Hg3P2S8

open access: yesAdvanced Physics Research, Volume 5, Issue 8, August 2026.
The defect diamond‐like material Hg3P2S8 (HPS) is systematically investigated using first‐principles methods to reveal the interplay between highly distorted HgS4 and rigid PS4 units. The HPS material exhibits a strong anisotropic second‐harmonic generation (SHG) response, favorable optical properties, and low thermal conductivity, highlighting its ...
