Prototheca zopfii has been developed as an experimental system for studying the control of cytokinesis and daughter-cell number variation in multiple fission. Although mean daughter-cell number increases linearly with growth rate, and this dependency is genetically controlled, pedigree analysis shows that daughter-cell number variation is not under direct genetic control. In a population growing in steady-state balanced growth, each cell has a given probability of dividing into 2, 4, 8 16, or 32 daughter-cells. These probabilities are independent of the division number of the cell in the preceding generation, and can be altered by changes in the culture medium.
威克氏原藻已被开发成为一种用于研究多分裂中胞质分裂控制和子细胞数量变化的实验系统。尽管平均子细胞数量随生长速率呈线性增加,且这种依赖性受遗传控制,但谱系分析表明子细胞数量变化不受直接遗传控制。在稳态平衡生长的群体中,每个细胞都有一定概率分裂为2、4、8、16或32个子细胞。这些概率与前一代细胞的分裂次数无关,并且可以通过培养基的变化而改变。
