Two viroids - the Columnea Latent Viroid (CLVd) and the Pepper Chat Fruit Viroid (PCFVd) - which are heavily involved in the Thai cultivation of tomato, eggplant, paprika, chili peppers and bolo maka, are now up to 100 times more effective and easier to detect. This is the result of a special exchange grant between Ghent University and ILVO on the one hand, and the Thai government on the other. Researcher Parichate Tangkanchanapas came with this grant to do a PhD in Belgium. He succeeded in molecular mapping the viroids in detail, predicting their harmfulness and developing a simple method that authorities can use at border controls. The viroids must not be present on export loads of vegetables and seeds from Thailand. Dangerous variant Both viroids have already been intercepted in quarantine procedures in other countries. It turned out that Thai CLVd strains cause more serious symptoms than, for example, the known European variants. Thai researcher Parichate Tangkanchanapas ...
