Tomato planta macho viroid (TPMVd) and Mexican papita viroid (MPVd) are two closely related (>90% sequence identity) members of the genus Pospiviroid. Their current status as members of separate species is based upon the reported ability of TPMVd to replicate in Gomphrena globosa and the inability of this viroid to evoke flower break in N. glutinosa. Characterization of a viroid recently isolated from diseased tomato plants grown in Mexico (identical to GenBank accession GQ131573) casts doubt on this earlier report and indicates that these viroids should be classified as members of a single species. Giving priority to the older name, we propose including both of these viroids in the current species Tomato planta macho viroid.
番茄雄性不孕病毒（TPMVd）和墨西哥马铃薯纺锤块茎类病毒（MPVd）是 Pospiviroid 属中两个密切相关的成员（>90%的序列同一性）。它们目前被归类为不同种，是基于 TPMVd 在鸡冠花中的复制能力，以及该类病毒不能引起蕹菜花朵破裂的报道。最近从墨西哥患病番茄植株中分离到的一种类病毒（与 GenBank 登录号 GQ131573 完全相同）的特性对这一早期报道提出了质疑，并表明这些类病毒应该被归类为一个种的成员。鉴于较早的名称，我们建议将这两种类病毒都归入当前的种番茄雄性不孕病毒。
