Examples of geminivirus names

The following examples illustrate the proposal.

1. When only one geminivirus species is known to infect the host:

Horseradish curly top virus

2. When more than one geminivirus species infects the host and each virus induces different symptoms:

Digitaria streak virus Digitaria striate mosaic virus

3. When more than one isolate or strain causes similar symptoms in a host and there is no species identification:

African cassava mosaic virus – [Kenya]* African cassava mosaic virus – [Uganda]* Tomato golden mosaic virus - common strain Tomato golden mosaic virus - yellow vein strain

*the fact that ACMV-KE was the first described ACMV automatically provides it the status of reference strain (hence did not require brackets) and therefore the indication of the country of origin is not absolutely required, but we felt that its indication was informative. In the case of the ACMV isolate from Uganda, as we currently do not have means to differentiate this isolate as a separate strain from the one from Kenya, we can only indicate its isolate origin and consequently we use the brackets. If later it was made possible to identify it as a separate strain of ACMV, it would suffice to drop the brackets, but the name would be unchanged.

4. When more than one isolate from the same location causes similar symptoms in a host and there is no species nor strain identification:

Maize streak virus – [Nigeria1] Maize streak virus – [Nigeria2] Maize streak virus – [Nigeria3]

5. When more than one strain of a given species causes similar symptoms in a host and there is a strain identification:

Tomato leaf curl New Delhi virus - Severe Tomato leaf curl New Delhi virus - Mild

6. When more than one isolate causes similar symptoms in a host and there is a species identification:

Tomato yellow leaf curl Sardinia virus Tomato yellow leaf curl Taiwan virus Tomato yellow leaf curl Thailand virus

7. When more than one isolate of a given strain of a given species causes similar symptoms in a host:

Tomato yellow leaf curl Sardinia virus – Spain [ 1 ] Tomato yellow leaf curl Sardinia virus – Spain [ 2 ]
