First report of Tomato chlorosis crinivirus in Taiwan and first report of Tomato chlorosis and Tomato infectious chlorosis criniviruses on zinnia
In Southern Taiwan, in spring 1998, pronounced yellowing symptoms were observed on lower leaves of tomato plants growing at a research centre and in several commercial fields. Symptoms suggested the possible presence of Tomato chlorosis crinivirus or Tomato infectious chlorosis crinivirus (ToCV and TICV - both on the EPPO Alert List). Molecular tests (specific digoxigenin-labeled riboprobes) revealed the presence of ToCV in 6 symptomatic tomato samples out of the 17 tested. No hybridization was obtained with the specific probe for TICV. On the same locations, similar symptoms were observed on zinnia plants. ToCV was detected in 5 zinnia plants (out of the 8 tested) and one of them was also found positive for TICV. According to the authors, this is the first published records of ToCV and TICV in zinnia plants, and of the presence of ToCV on tomatoes in Taiwan.
