Isolation of polysomes from Nostoc sp. MAC and translation of messenger RNA in a heterologous cell-free system

Polysome turnover in immobilized cells of Nostoc commune (cyanobacteria) exposed to water stress

Water stress induced changes in the polysome content of immobilized cells of the desiccation-tolerant cyanobacterium Nostoc commune UTEX 584. Cells maintained an intact protein synthesis complex during 2 h of drying at -99.5 MPa. Polysomes were not recovered from cells subjected to extended periods of desiccation.

Polyadenylated RNA in two filamentous cyanobacteria

Polyadenylated RNA was detected in the cyanobacteria Nostoc sp. strain MAC and Anabaena variabilis by oligodeoxythymidylic acid-cellulose chromatography and by hybridization to [3H]polyuridylic acid. Polyadenylate tracts from A. variabilis were located at the 3' end of RNA chains and had an estimated length of 15 to 22 nucleotides.
