Brassica plants with increased photosynthetic rate and seed yield

Enhancing crop yield is a key objective in plant breeding, and it underpins efforts to achieve global food security amid projected population growth. Recently, improving photosynthesis has emerged as a promising strategy for yield improvement. One way to improve photosynthesis is to engineer plants that can assimilate more carbon dioxide (CO₂). This in turn can increase biomass which can help obtain greater harvests and improved resource-use efficiency. This increase in photosynthetic capacity also has the potential added benefit of reducing atmospheric CO₂—a major greenhouse gas—by enhancing carbon storage in plant biomass, thus contributing to the mitigation of CO₂-driven global warming.
