Viroids are small, noncoding and nonencapsidated RNAs that infect plants. To establish systemic infection, viroid genomes or their derivatives must interact directly with cellular factors. There is increasing evidence that subcellular localization and systemic trafficking of viroid RNAs are regulated, likely via interactions between viroid RNA cis elements and specific cellular proteins. Here we summarize recent progress on the characterization of viroid structures and host proteins that may play important roles in trafficking. We also discuss critical issues that need to be addressed in future investigations.
