Synthese Poly(A)-haltiger RNA in auswachsenden Sporen vonBacillus subtilis

Abstract

The synthesis of poly(A)-containing RNA in outgrowing spores of Bacillus subtilis was studied. A significant amount of RNA puls-labelled with 3H-uridine is polyadenylated. With the beginning of RNA synthesis in outgrowing spores labelled poly(A)-containing RNA was detected. The amount of poly(A)-RNA during the outgrowth and first cell division remains constant. Besides poly(A)-RNA the synthesis of tRNA and rRNA occurs. These results indicate a simultaneous activation of synthesis of tRNA, rRNA as well as of poly(A)-containing RNA during outgrowth of B. subtilis spores.
