在日本广岛县的商业番茄植株上发现了一种类病毒病，会导致叶子萎黄和矮化。将受感染植物的茎嫁接到健康植物上会导致健康植物出现相同的症状。从受感染的植物组织中分离出小RNA，并在机械接种番茄幼苗后3-4周引起相同的症状。核苷酸测序表明，致病病原体是番茄褪绿矮化类病毒（TCDVd），与之前报道的加拿大分离株具有 98% 的核苷酸序列同一性。这是日本首次对番茄植株的 TCDVd 感染进行描述。
A viroid disease causing chlorosis of leaves and dwarfism was found on commercial tomato plants in Hiroshima Prefecture, Japan. Grafting of stems from infected plants onto healthy plants resulted in the same symptoms on the healthy plants. Small RNAs were isolated from infected plant tissue and caused identical symptoms by 3-4 week after mechanical inoculation of tomato seedlings. Nucleotide sequencing indicated that the causal pathogen was Tomato chlorotic dwarf viroid (TCDVd) sharing 98% nucleotide sequence identity with that of a Canadian isolate reported previously. This description is the first of TCDVd infection of tomato plants in Japan.
