Monsi和Saeki在1953年的论文（Japanese Journal of Botany 14：22-52）不仅在冠层光合作用的数学建模方面，而且在叶冠层季节变化的生态发展研究方面都是开创性的。SCOPE以氮素优化理论为基础，综述了单叶、草本和乔木3种不同尺度下高效光合系统的构建和维持机制。首先简要介绍了冠层和单叶氮素优化理论。其次，讨论了叶片厚度在CO2扩散和光合作用中的意义。第三，讨论了草本植物叶片光合特性的调节机制。特别是，糖传感，氧化还原控制和细胞分裂素的作用突出。最后，考虑了树的发展。结论植物高效光合系统的构建和维持是多种机制共同作用的结果。这些重要的生态机制的分子背景应该澄清。树的构建机制不能仅仅用氮素优化理论来解释。管道模型理论在其微分形式的建议，可能是一个潜在的工具，在未来的研究在这一研究领域。
BACKGROUND AND AIMS The paper by Monsi and Saeki in 1953 (Japanese Journal of Botany 14: 22-52) was pioneering not only in mathematical modelling of canopy photosynthesis but also in eco-developmental studies of seasonal changes in leaf canopies. SCOPE Construction and maintenance mechanisms of efficient photosynthetic systems at three different scaling levels--single leaves, herbaceous plants and trees--are reviewed mainly based on the nitrogen optimization theory. First, the nitrogen optimization theory with respect to the canopy and the single leaf is briefly introduced. Secondly, significance of leaf thickness in CO2 diffusion in the leaf and in leaf photosynthesis is discussed. Thirdly, mechanisms of adjustment of photosynthetic properties of the leaf within the herbaceous plant individual throughout its life are discussed. In particular, roles of sugar sensing, redox control and of cytokinin are highlighted. Finally, the development of a tree is considered. CONCLUSIONS Various mechanisms contribute to construction and maintenance of efficient photosynthetic systems. Molecular backgrounds of these ecologically important mechanisms should be clarified. The construction mechanisms of the tree cannot be explained solely by the nitrogen optimization theory. It is proposed that the pipe model theory in its differential form could be a potential tool in future studies in this research area.
