摘要

属于 Avsunviroid 和 Pelamovirod 属（Avsunviroidae 科）的病毒复制并积累在受感染细胞的叶绿体中。在本报告中，我们通过使用地高辛-UTP 标记的核糖体进行 RNA 原位杂交证实，茄潜伏病毒（ELVd）的阳性链（茄潜伏病毒是 Avsunviroidae 科中 Elaviroid 属的唯一成员）也会在感染细胞的叶绿体中积累。然而，将 ELVd 的原位杂交信号与真正的叶绿体和核非编码 RNA（如叶绿体 5S rRNA 和 U1 小核 RNA）的信号进行比较后发现，这种病毒也存在于受感染细胞的细胞核中。这些结果表明，Avsunviroidae 科病毒的亚细胞定位可能比以前假定的更为复杂，在感染周期中会动态地存在于多个区室中。

Eggplant latent viroid is located in the chloroplasts and nuclei of eggplant infected cells.

Viroids that belong to genera Avsunviroid and Pelamovirod (family Avsunviroidae) replicate and accumulate in the chloroplasts of infected cells. In this report, we confirmed by RNA in situ hybridization using digoxigenin-UTP-labelled riboprobes that the positive strands of eggplant latent viroid (ELVd), the only member of genus Elaviroid within the family Avsunviroidae, also accumulate in the chloroplasts of infected cells. However, comparison of ELVd in situ hybridization signals with those from bona fide chloroplastic and nuclear non-coding RNAs, such as chloroplast 5S rRNA and U1 small nuclear RNA, supports the notion that this viroid is also present in the nuclei of infected cells. These results suggest that the subcellular localization of viroids within the family Avsunviroidae may be more complex than previously assumed with dynamic presence in several compartments during the infectious cycle.

期刊介绍： Virology Journal is an open access, peer reviewed journal that considers articles on all aspects of virology, including research on the viruses of animals, plants and microbes. The journal welcomes basic research as well as pre-clinical and clinical studies of novel diagnostic tools, vaccines and anti-viral therapies. The Editorial policy of Virology Journal is to publish all research which is assessed by peer reviewers to be a coherent and sound addition to the scientific literature, and puts less emphasis on interest levels or perceived impact.
