对31株C.分离具有改变的趋光反应的莱茵衣藻。所有突变体的生长都是正常的，除了1个突变体外，它们没有大体形态畸变。一个突变体产生额外的鞭毛。根据突变体的异常反应可将其分为5类：慢阳性、无反应、慢阴性、快阴性和变异。随机运动的突变体的特点。大约有一半与野生型没有区别;其他人表现出不稳定或旋转的运动，而不是相对直线的路径。这些突变体可用于趋光性细胞基础的遗传和生化研究。
A group of 31 mutants of C. reinhardtii with altered phototactic responses was isolated. Growth of all the mutants was normal, and with 1 exception they had no gross morphological aberrations. One mutant produced supernumerary flagella. The mutants can be subdivided into 5 phenotypic classes on the basis of their abnormal responses: slow positive, no response, slow negative, fast negative and variable. Random motility of the mutants was characterized. About half were indistinguishable from wild type; the others exhibited jerky or twirly movements instead of relatively straight paths. These mutants can be used for genetic and biochemical studies of the cellular basis of phototaxis.
