Deoxyribonuclease Digestion of the Nucleic Acid from Carnation Etched Ring Virus. I. Fujisawa, Plant Pathology Laboratory, Faculty of Agriculture, Nagoya University, Nagoya, Japan; M. Rubio-Huertos(2), and C. Matsui(3). (2)(3)Instituto Jaime Ferran de Microbiologia, CSIC, Madrid, Spain. Phytopathology 62:810-811. Accepted for publication 5 October 1971. DOI: 10.1094/Phyto-62-810.

Carnation etched ring virus was purified from infected Silene armeria by differential centrifugation and sucrose density-gradient centrifugation. The purified preparation revealed a typical ultraviolet absorption spectrum for nucleoprotein, and consisted of infective particles about 42 nm in diameter. The nucleic acid isolated from the purified virus was digested completely with deoxyribonuclease, but not digested with ribonuclease.
