Viroids can be transmitted vertically and/or horizontally by pollen. Tomato planta macho viroid (TPMVd) has a high rate of horizontal transmission by pollen, whereas potato spindle tuber viroid (PSTVd) does not. To specify the domain(s) involved in horizontal transmission, four viroid chimeras were created by exchanging the terminal left (n,) and/or pathogenicity (P) domains between PSTVd and TPMVd. PSTVd-based chimeras containing TPMVd-TL and P, or TPMVd-TL alone, displayed a high rate of horizontal transmission. TPMVd-based chimeras containing PSTVd-TL and P lost infectivity, and those containing PSTVd-TL alone displayed a low rate of horizontal transmission. In addition, the vertical transmission rate was also higher in the mutants containing TPMVd-TL than in the others. These findings indicate that the sequences or structures in the TL and P (although the role is limited) domains are important not only for horizontal but also for vertical transmission by pollen.
