Interpretive Summary: Members of the Closteroviridae have emerged as a major problem in world agriculture as the number of diseases caused by members of the family have multiplied at an alarming rate in the last two decades. Diodia vein chlorosis virus (DVCV) is an understudied whitefly-transmitted closterovirus. Given the presence of the primary host for the virus in major agricultural production areas in the United States, we characterized the virus at the molecular level, demonstrating that it belongs in the genus Crinivirus (Closteroviridae). We also developed detection protocols and evaluated vector transmission and host range among hosts known to harbor viruses closely related to DVCV. Results demonstrated DVCV is a narrow host range virus related to other subgroup 1 criniviruses and can be transmitted by two whitefly species in the genus Trialeurodes.
