Potato spindle tuber viroid (PSTVd) effects tomato, pepper and other solanaceous hosts. Symptoms include stunting, severe yellowing and distortion of the leaves. PSTVd is seed transmitted. 1500 seeds are tested for Potato spindle tuber viroid (PSTVd) by real time RT-PCR (TaqMan). However, this TaqMan assay also detects Tomato chlorotic dwarf viroid (TCDVd), Mexican papita viroid (MPVd) and Tomato planta macho viroid (TPMVd). If the sample was positive, PCR and sequencing would be required to identify which viroid was present. There would be an additional charge for this testing – see ‘Identification and confirmation of pospiviroid seed positive test, details below’.
