Transcripts of the viroid central conserved region contain the local tertiary structural element found in full-length viroid

The viroid central conserved region (CCR) is highly conserved among different viroids and is thought to be involved in viroid replication. A novel tertiary structure occurs in the CCR of native circular potato spindle tuber RNAs. To permit more detailed studies of this structural element, a small RN...

description The viroid central conserved region (CCR) is highly conserved among different viroids and is thought to be involved in viroid replication. A novel tertiary structure occurs in the CCR of native circular potato spindle tuber RNAs. To permit more detailed studies of this structural element, a small RNA oligonucleotide containing the CCR of the viroid genome was synthesized. The tertiary structure of these CCR transcripts was examined by UV-crosslinking of the RNA, followed by mapping of the crosslink using limited alkaline digestion and classical RNA secondary analysis. The CCR transcript was found to undergo UV-crosslinking between the same two bases as in full-length viroid, indicating that the tertiary structure is the same and that the CCR transcript will be useful for the affinity purification of host components.
