Cassava, bean and maize leaves were fed with(14)CO2 in light and the primary products of photosynthesis identified 5 and 10 seconds after assimilation. In maize, approximately three quarters of the labelled carbon was incorporated in C4 acids, in beans about two thirds in PGA, and in cassava approximately 40-60% in C4 acids with 30-50% in PGA. These data indicate that cassava possesses the C4 photosynthetic cycle, however due to the lack of typical Kranz anatomy appreciable carbon assimilation takes place directly through the Calvin-Benson-Bassham cycle.
木薯、豆类和玉米叶片在光照下用 14CO2 进行饲喂，并在同化后 5 和 10 秒鉴定光合作用的初级产物。在玉米中，大约四分之三的标记碳被掺入 C4 酸中，在豆类中大约三分之二被掺入 PGA 中，而在木薯中大约 40-60%被掺入 C4 酸中，30-50%被掺入 PGA 中。这些数据表明木薯具有 C4 光合作用循环，然而，由于缺乏典型的 Kranz 解剖结构，可观的碳同化直接通过卡尔文-本森-巴斯汉姆循环进行。
