Detection of a latent infectious agent that protects against infection by chrysanthemum chlorotic mottle viroid


, : Detection of a latent infectious agent that protects against infection by chrysanthemum chlorotic mottle viroid. Phytopathology 65(9): 1000-1003

A latent infectious agent (ChCMV-NS) that protects against ChCMV was found in cvs. of Chrysanthemum morifolium; it produced no recognizable symptoms but is detectable by its complete protection against the severe str. of ChCMV. At least 8 days of incubation are required after inoculation of ChCMV-NS for complete protection against ChCMV. Opt. detection of ChCMV-NS occurred at 21 deg C and the opt. for detection of ChCMV from crude extracts of source plants was 21-24 deg.
