CAM植物的发现以一种相当不寻常的方式开始,当罗马人发现他们的饮食中使用的一些植物叶子在早晨收获时尝到了苦味,但如果在当天晚些时候收获则不那么苦。 一位名叫Benjamin Heyne的科学家在品尝苔藓(Bryophyllum calycinum)时发现了同样的事情,该植物属于景天科(Crassulaceae)(因此,这个过程的名称为“Crassulacean酸代谢”)。 为什么他正在吃这种植物尚不清楚,因为它可能有毒,但他显然幸存下来并刺激研究为什么会发生这种情况。 然而,几年前,一位名叫Nicholas-Theodore de Saussure的瑞士科学家写了一本名为Recherches Chimiques sur la Vegetation(植物化学研究)的书。 他被认为是第一个记录CAM存在的科学家,正如他在1804年所写的那样,仙人掌等植物的气体交换生理学与薄叶植物的生理学不同。


The discovery of CAM plants began in a rather unusual way, when the Romans discovered that some of the plant leaves used in their diet tasted bitterness in the morning harvest, but not so bitter if harvested later in the day. A scientist named Benjamin Heyne discovered the same thing when he tasted the moss (Bryophyllum calycinum), which belongs to the Crassulaceae (hence the name “Crassulacean acid metabolism”). It is unclear why he is eating this plant because it may be toxic, but he apparently survived and stimulated the study of why this happened. However, a few years ago, a Swiss scientist named Nicholas-Theodore de Saussure wrote a book called Recherches Chimiques sur la Vegetation. He is considered to be the first scientist to document the existence of CAM. As he wrote in 1804, the gas exchange physiology of plants such as cacti is different from the physiology of thin leaf plants.
