Co-infection of Carrot red leaf virus (CtRLV), Carrot mottle virus (CMoV) and Carrot red leaf virus associated RNA (CtRLVaRNA) causes Carrot motley dwarf (CMD) disease. This study examined the capacity of the aphid Myzus persicae at transmitting viruses associated with CMD. M. persicae exposed to CMD-infected chervil plants transmitted CtRLV-, CMoV- and CtRLVaRNA to disease-free chervil, fennel, celery, carrot, cilantro, and parsley, as shown by RT-PCR using specific primers. Recipient plants developed typical CMD symptoms. Sequence analysis of the amplified virus genes showed high sequence diversity with corresponding sequences available in GenBank. This study expands on Cavariella aegopodii, the only previously recognized aphid vector of CMD-causing viruses.
