Condensed nucleoprotein helices containing circular ssDNA may represent a novel type of plant virus

Virus-like particles associated with leaf yellowing and leaf distortion in Diffenbachia (dumbcane) and Spathiphyllum (peace lily) (Aracae) consisted of narrow (6 nm) nucleoprotein filaments that formed condensed rod-shaped helices measuring 20 x 250 nm. Electrophorteic analyses and nuclease digestio...

Description
Summary:Virus-like particles associated with leaf yellowing and leaf distortion in Diffenbachia (dumbcane) and Spathiphyllum (peace lily) (Aracae) consisted of narrow (6 nm) nucleoprotein filaments that formed condensed rod-shaped helices measuring 20 x 250 nm. Electrophorteic analyses and nuclease digestion assays indicated that these virus-like structures contain a major structural protein of approx. 44 kDa and a circular ssDNA approx. 10 kb in length. Initial attempts to transmit the disease and/or the putative vira pathogen by mechanical inoculation have been unsuccessful, and nucleotide and amino acid sequence searches have found no significant identity to any known viral sequences.
