| Abstract | Low molecular weight plant ribonucleic acids including viroid-RNA molecules which are soluble in 2M lithium chloride were electrophoresed in the 0M to 8M urea-gradient polyacrylamide gel. Although the linear viroid-RNA molecules migrated at a similarrate across the urea-gradient gel under the denaturing temperature, the circular viroid-RNA molecules moved more rapidly at low urea-gradient region than at high urea-gradient region. Consequently, the migration of the circular viroid-RNA molecules showed a sudden shift across the band of linear forms in the midrange of the urea-gradient gels. Electrophoretic mobilities of the circular viroid-RNA molecules seemed to depend mainly on the concentration of urea in the denaturing urea-gradient gels. | ||
