(Submitter supplied) Background: Eukaryotic organisms have evolved a series of mechanisms to regulate transposable element (TE) expression based on RNA silencing. In plants, the initial step in the recognition of TE transcripts relies on microRNAs, but this is unlikely to take place in the pollen grain where natural reactivation of TE transcription occurs but microRNAs accumulate to low levels. We investigated small non-coding RNA accumulation in plants and found conserved tRNA-derived RNA fragment (tRF) accumulation in the pollen grain or analogous reproductive structure in a variety of plant species. more...
