Poplar-1 RNA motif explained

poplar-1
Symbol:	poplar-1
Rfam:	RF03041
Rna Type:	Gene sRNA

The poplar-1 RNA motif is a conserved RNA structure that was discovered by bioinformatics.^[1] As of 2018, all known examples of the poplar-1 motif are found in metagenomic sequences; no poplar-1 RNA has yet been found in a classified organism. Poplar-1 RNAs were particularly common in a metagenomic sample from decaying yellow poplar tree wood chips.^[2]

Poplar-1 RNAs generally occur in sequencing contigs that are relatively small. Therefore, there is not enough information on surrounding genes to be able to determine whether poplar-1 RNAs are likely to function as cis-regulatory elements or whether they more likely operate in trans as small RNAs.
