tomato, petunia
TCDVd
Closely related to Potato spindle tuber viroid. Few occurrences in the US. Though Capsicum annum is often tested for this viroid, there is no evidence that it is a host.
3 Known Hosts
Solanum lycopersicum
tomato
No
TCDVd-2,TCDVd-3,TCDVd-4
Pathway not proven. Data conflicting or research used artificially inoculated plants only. Increased detections of the viroid in the world increases speculation of seed as a pathway but seed transmission is still debatable (Ling, personal communication, 2018)
Yes
RT-PCR
RT-PCR is the standard method of the NSHS. Seed is often tested, though seed as a pathway is not sufficiently.

Petunia spp.
petunia
No
TCDVd-3,TCDVd-5,TCDVd-6
Pathway not Proven. One reference found where Tomato chlorotic dwarf viroid was seed transmitted in artificially inoculated plants of Petunia, . Two other references found Tomato chlorotic dwarf viroid in petunia stocks, but seed were not tested. No references found where seed was naturally infected with Tomato chlorotic dwarf viroid.
RT-PCR is used to test tomato seed for this viroid.
