Crystal structure-guided exchange of mobile elements from red algal Rubisco into a related bacterial Rubisco enabled us to identify amino acid substitutions that enhance carbon dioxide (CO2) fixation. In tobacco plants, the improved Rubisco supported a two-fold increase in photosynthetic rates compared with plants producing wild-type bacterial Rubisco.

Bailey-Serres, J., Parker, J. E., Ainsworth, E. A., Oldroyd, G. E. D. & Schroeder, J. I. Genetic strategies for improving crop yields. Nature 575, 109–118 (2019). This review examines the broad range of genetic strategies being used to enhance sustainable crop production under current and future climates.
Whitney, S. M., Baldet, P., Hudson, G. S. & Andrews, T. J. Form I Rubiscos from non-green algae are expressed abundantly but not assembled in tobacco chloroplasts. Plant J. 26, 535–547 (2001). This paper reports the characterization of GmRubisco and its potential to improve crop photosynthesis and shows how the assembly requirements of algal Rubisco are not met in leaf chloroplasts.

A computational analysis extrapolating from kinetic properties to canopy photosynthesis. Plant Cell Env. 27, 155–165 (2004). This paper presents crop canopy modelling simulations showing how increases in Rubisco performance might translate into gains in productivity and yield.

Sci. 117, 25890–25896 (2020). This paper demonstrates the high expression levels of RsRubisco in plant chloroplasts and the requirement for co-expression of CbbX to ensure maximum RsRubisco activity.
