Epidemiology of two Diodia virginiana criniviruses

The genus Crinivirus, family Closteroviridae, includes several emerging Viruses that cause disease in crops around the world. Diodia virginiana, family Rubiaceae, a widespread noxious weed of the southeastern United States, is known to be infected by a crinivirus, Diodia vein chlorosis virus (DVCD)....

Description
Summary:The genus Crinivirus, family Closteroviridae, includes several emerging Viruses that cause disease in crops around the world. Diodia virginiana, family Rubiaceae, a widespread noxious weed of the southeastern United States, is known to be infected by a crinivirus, Diodia vein chlorosis virus (DVCD). During the original characterization of DVCV, herbaceous hosts were tested as alternate hosts for the virus but none of the major crops of the Southeast was included in that study. There are no detection tests available for DVCV and given the emergence of several criniviruses, we began developing detection tests for the virus and tested the possibility that crops in the Southeast could be infected with the virus. During the molecular characterization process, we determined that there were two criniviruses infecting Diodia, both transmitted by the greenhouse and banded winged whiteflies (Trialeurodes vaporariorum and T. abutilonea, respectively). The Diodia viruses belong to Crinivirus group 1, along with the small fruit-infecting criniviruses and Potato yellow vein virus. The similarity of the diodia viruses with the small fruit-infecting criniviruses probed us to test the possibility that the two diodia viruses can infect Rosaceae hosts, especially blackberry, a crop affected by two criniviruses that can synergistically cause blackberry yellow vein disease.
