Kortschak 等人初步确定 C4-二羧酸是高等植物的主要光合产物。 （6）。现在已知这种光合作用碳固定途径发生在许多被子植物类群中，并且该途径的特定方面已受到相当多的关注 (5)。 C、植物的叶子具有由同心维管束鞘和围绕维管束的叶肉细胞层组成的特征解剖结构。这两个不同的细胞层具有叶绿体，其具有结构或大小二态性。束鞘细胞叶绿体的功能与淀粉体相同 (9, 10)。叶绿体，随后通过 Calvin 重新固定
The initial determination that C4-dicarboxylic acids were the primary photosynthetic products in a higher plant was made by Kortschak et al. (6). This photosynthetic carbon-fixa-tion pathway is now known to occur in many angiosperm taxa, and specific aspects of the pathway have received considerable attention (5). The leaves of C, plants have a characteristic anatomy consisting of concentric bundle sheath and mesophyll cell layers around the vascular bundles. These two distinct cell layers possess chloroplasts which have either structural or size dimorphism. The bundle sheath cell chloroplasts function as amyloplasts (9, 10). chloroplasts, subsequent refix- tion via Calvin
