To meet the challenge of increasing crop yield for a burgeoning world population, it has become apparent that photosynthetic capacity must be increased per unit leaf area to improve yield potential. Plants with the C4 photosynthetic pathway are major contributors to world food production and bioenergy supply. The aim of this study is to explore ways of enhancing C4 photosynthesis using directed molecular modifications of Setaria viridis, the model monocot C4 species, and through high throughput fluorescence imaging of photosynthesis in Setaria italica accessions. This will provide new insights into rate limiting steps of C4 photosynthesis needed for C4 crop improvement.

为了应对为迅速增长的世界人口增加作物产量的挑战，显然必须增加每单位叶面积的光合能力以提高产量潜力。具有C4光合途径的植物是世界粮食生产和生物能源供应的主要贡献者。本研究的目的是探索提高C4光合作用的方法，使用定向分子修饰的狗尾草，模式单子叶C4物种，并通过高通量荧光成像的光合作用在谷子italica加入。这将为C4作物改良所需的C4光合速率限制步骤提供新的见解。
