Members of the family have single-stranded circular RNA genomes that adopt a rod-like or a quasi-rod-like conformation. These genomes contain a central conserved region that is involved in replication in the nucleus through an asymmetric RNA-RNA rolling-circle mechanism. Members of the family lack the hammerhead ribozymes that are typical of viroids classified in the family . The family includes the genera , , , and , with >25 species. This is a summary of the ICTV Report on the family , which is available at ictv.global/report/pospiviroidae.
该科病毒的单链环状 RNA 基因组呈棒状或准棒状结构。这些基因组含有一个中央保守区，通过非对称 RNA-RNA 滚环复制机制在核内进行复制。该科病毒缺乏通常存在于归类于该科的类病毒中的锤头核酶。科包括 、 、 、 属，共有超过 25 个种。这是 ICTV 关于该科的报告摘要，可在 ictv.global/report/pospiviroidae 上查阅。
