Abstract

The flagella of the unicellular green alga Chlamydomonas reinhardtii are controlled by a number of sophisticated homeostatic mechanisms which ensure that the flagella are maintained at a specific length, and that each cell has two flagella of equal length. Mutants with defects in flagellar length control have been obtained, defining at least nine genes that are involved in the control of flagellar length and the equality of flagellar length. The active machinery involved in flagellar length control requires that cells precisely measure the length of their flagella and drastically alter flagellar protein production and assembly when necessary to maintain desired lengths.

衣藻鞭毛长度的控制
莱茵衣藻(Chlamydomonas reinhardtii)单细胞绿藻的鞭毛由许多复杂的稳态机制控制,这些机制确保鞭毛保持在特定的长度,并且每个细胞有两个长度相等的鞭毛。已经获得了鞭毛长度控制缺陷的突变体,定义了至少9个参与鞭毛长度控制和鞭毛长度相等的基因。参与鞭毛长度控制的活性机制要求细胞精确测量鞭毛的长度,并在必要时大幅度改变鞭毛蛋白的生产和组装,以保持所需的长度。
