Abstract

Freeze-fracture replicas reveal that five distinct types of intramembranous particle arrays coexist within a small sector of the C. reinhardtii cell flagellar membrane. Of these, three are newly described in this report. (a) Flagellar bracelets, which encircle the flagellar bases, appear to be intrinsically ordered strands of particles of unknown function. (b) Strut arrays, representing nine sites where the basal body attaches to the membrane, appear to serve a mechanical function. (c) Contractile vacuole arrays, which develop into circular plaques of particles, appear to serve as "membrane gates" through which water is discharged from the cell.

摘要

冷冻蚀刻复制品显示,莱茵衣藻细胞鞭毛膜的一个小区域内共存着五种不同类型的膜内颗粒阵列。其中,有三种是本报告中新描述的。(a) 鞭毛手环环绕着鞭毛基部,似乎是功能未知的颗粒的内在有序链。(b) 支柱阵列代表基体与膜附着的九个位点,似乎起到机械作用。(c) 收缩泡阵列发展成颗粒状的圆形斑块,似乎充当 “膜门”,水通过它从细胞中排出。
