Abstract

Tetrahymena pyriformis which has been starved for 20 h by incubation in buffer, and then deciliated, can regenerate its cilia in about 90 min while still in suspension in non-nutrient medium. The process of reciliation is accompanied by protein synthesis which begins a few minutes after deciliation and by synthesis of ribosomal and messenger RNAs during a period extending from about 1 h to about 3 h after deciliation. Although net synthesis of RNA remains at a very low level until 1 h after deciliation, a qualitative change in the translatable poly(A)-containing messenger RNA content of deciliated cells, and in particular, formation of beta-tubulin mRNA can be detected almost immediately after deciliation.

Abstract

In the course of our studies on the messenger RNA of bacteriophage λ, a low molecular weight RNA, l1, synthesized very early after induction of the prophage, has been identified. It has been possible to obtain it in a very pure state through specific hybridization with the light strand of λ DNA. The results of two-dimensional electrophoresis of pancreatic ribonuclease and ribonuclease T1 digests indicate that l1 is a homogeneous species. Some of its properties were investigated to elucidate whether they were most similar to those of transfer RNA, 5 s RNA or messenger RNA. Although its electrophoretic mobility is similar to that of transfer RNA and 5 s RNA, it is definitely more unstable than these species and in this respect rather like messenger RNA. Its function is yet unknown.
