Properties of Single- and Double-stranded Ribonucleic Acid from Barley Plants Infected with Bromegrass Mosaic Virus

Abstract

Incorporation of 32P into nucleic acids in barley plants infected with bromegrass mosaic virus (BMV) was analyzed by chromatography on methylated albumin kieselguhr (MAK) columns. Treatment with actinomycin D reduced the synthesis of ribosomal ribonucleic acid (RNA) to low levels and allowed the detection of the three components of BMV-RNA in vivo. The kinetic study on 32P incorporation into these BMV-RNA components suggested that a single cleavage occurred in some of the intact RNA shortly after completion of its synthesis, giving rise to the small and medium components. Chromatographic analyses also revealed a double-stranded, ribonuclease-resistant RNA which has been purified by differential extraction, sucrose-density gradient centrifugation, and MAK column chromatography. This RNA sediments at approximately 14S, is alkali-labile, and has a sharp thermal transition with a Tm of 96 C in 0.1 × standard saline citrate buffer, as determined by susceptibility to ribonuclease. The RNA is absent in uninfected barley plants.
