Plant-based carboxysomes: another step toward increased crop yields.

Synthetically reconstructed carboxysomes form the basis of CO2-concentrating mechanisms (CCMs) that could enhance the photosynthetic efficiency of crops and improve yield. Recently, Chen et al. revealed another step toward the reconstruction of bacterial carboxysomes in plants, reporting the formation of almost-complete carboxysomes in the chloroplast of Nicotiana tabacum.
