Arabidopsis plants expressing only the redox-regulated Rca-α isoform have constrained photosynthesis and plant growth.

The Plant journal : for cell and molecular biology - 1 Sept 2020

Abstract excerpt

Rubisco activase (Rca) facilitates the release of sugar-phosphate inhibitors from the active sites of Rubisco and thereby plays a central role in initiating and sustaining Rubisco activation. In Arabidopsis, alternative splicing of a single Rca gene results in two Rca isoforms, Rca-α and Rca-β. Redox modulation of Rca-α regulates the function of Rca-α and Rca-β acting together to control Rubisco activation....
