Control of initiation and elongation of cilia during ciliary regeneration in Tetrahymena

Tetrahymena thermophila strain B could regenerate approximately 10% of its somatic ciliary mass in concentrations of cycloheximide believed to block all cytoplasmic protein synthesis. A quantitative study of the relative numbers and lengths of cilia regenerated in the presence and absence of cycloheximide under a variety of conditions suggested that specific initiation and elongation protein factors are involved in the control of ciliary morphogenesis in Tetrahymena.
