Abstract:
New viruses are being discovered in droves thanks to high throughput sequencing. This is not true of viroids, pure RNA parasites so small that they encode no proteins. The comparative dearth of newly discovered viroids could be due to genuine rarity or it could be that, due to their extremely small size, viroids are lost in the vast quantities of data. By curating a database of all known sequences and developing a purpose-built pipeline for viroid and viroid-like RNA discovery, we show that there is indeed significant diversity of these agents present within metatranscriptomic samples.
