AGO1-dependent Small RNA in Arabidopsis Identified by High-Throughput Sequencing

ABSTRACT: The goal of this study was to identify AGO1-dependent miRNA and tasiRNA in Arabidopsis by sequencing small RNA from wild type (Col-0) and ago1-25 plants. Keywords: Small RNA Sequencing-by-synthesis technology was used to sequence small RNA from flower tissue (stages 1-12) from wild-type (Col-0) and ago1-25 Arabidopsis thaliana plants. Three biological replicates were sequenced for both Col-0 and ago1-25.

MicroRNA (miRNA)-guided cleavage initiates entry of primary transcripts into the transacting siRNA (tasiRNA) biogenesis pathway involving RNA-DEPENDENT RNA POLYMERASE6, DICER-LIKE4, and SUPPRESSOR OF GENE SILENCING3. Arabidopsis thaliana TAS1 and TAS2 families yield tasiRNA that form through miR173-guided initiation-cleavage of primary transcripts and target several transcripts encoding pentatricopeptide repeat proteins and proteins of unknown function. Here, the TAS1c locus was modified to prod  ...[more]
