Two novel aspects of Tomato chlorotic dwarf viroid (TCDVd) are reported, namely that TCDVd was detected in symptomless plants of Vinca minor, a trailing ground cover surviving at subzero temperatures (−12°C); and that TCDVd was seed-borne in tomato and detected
in high percentages in tomato seeds and seedlings. Soaking seeds in a low concentration of sodium hypochlorite did not eliminate
the viroid. The sequence analysis showed that the TCDVd isolate consists of 360 nucleotides and has sequence identity between
96% to 99% with isolates of TCDVd from other hosts. 相似文献
