摘要

An ornamental plant, Nandina domestica, has been found to be infected for the first time with Apple stem grooving virus (ASGV) in New Zealand and Alternanthera mosaic virus (AltMV) in Oklahoma, USA. ASGV may infect N. domestica latently and the symptoms observed in New Zealand are thought to be induced by the co-infecting Cucumber mosaic virus (CMV). Similarly, Plantago asiatica mosaic virus (PlAMV, syn. Nandina mosaic virus) was found to co-infect with AltMV in the USA, and therefore the observed symptoms may be induced by AltMV and/or PlAMV.
