Function of Helper and Satellite Viruses. Virions associated with helper virus, but independent from its functions during replication. Virions found in leaves and roots. Dogwood mosaic virus is serologically more distant from arabis mosaic virus than is grapevine fanleaf virus. It, unlike cucumber mosaic virus, infects cowpea systemically and, unlike broad bean wilt, induces local lesions in cucumber.
Serological tests are best for diagnosis.
