首次在矮牵牛（Petuniaspp.）通过全基因组序列分析，鉴定为番茄褪绿矮缩类病毒（Tomato chlorotic dwarf vioid，TCDVd）。这些矮牵牛植物是番茄或马铃薯植物的可能接种源，因为TCDVd在这些植物上诱导严重症状。该来自日本的矮牵牛分离物的基因组序列与来自荷兰和英国的矮牵牛分离物以及来自日本的番茄分离物具有100%的同一性。系统发育分析表明，所有矮牵牛分离物和来自日本的番茄分离物形成了一个单系分支。
A viroid was detected for the first time in symptomless petunia plants (Petuniaspp.) and identified asTomato chlorotic dwarf viroid(TCDVd) based on an analysis of the complete genomic sequence. These petunia plants are a likely source of inoculum for tomato or potato plants because TCDVd induces severe symptoms on these plants. The genomic sequence of this petunia isolate from Japan shared 100 % identity with petunia isolates from the Netherlands and United Kingdom and a tomato isolate from Japan. Phylogenetic analysis showed that all petunia isolates and the tomato isolate from Japan formed a monophyletic clade.
