Abstract
Zooxanthellae isolated from reef corals and Tridacna crocea incorporate labeled carbon dioxide photosynthetically. In the presence of some component of the host tissue, up to 40 percent of the labeled algal photosynthate is liberated primarily as glycerol. Excretion of glycerol by the algae in situ and its control and utilization by the host may represent a mechanism by which zooxanthellae contribute to produtctivity of coral reefs.
摘要
从珊瑚礁中分离出来的虫黄藻和大砗磲可以通过光合作用将标记的二氧化碳转化为有机物质。在宿主组织的某些成分存在的情况下，多达 40%的标记藻类光合作用产物主要以甘油的形式释放。藻类在原位分泌甘油，以及宿主对其的控制和利用，可能代表了虫黄藻为珊瑚礁生产力做出贡献的一种机制。
