Arabidopsis thaliana small RNAs sequences identified using high-throughput 454 sequencing technology


ABSTRACT: To determine the extent to which the major small RNA pathways functions across the Arabidopsis thaliana genome, small RNA populations from several tissues of wild-type (wt) and mutant plants were amplified by RT-PCR and sequenced using high-throughput 454 sequencing technology. Keywords: small RNAs, high-throughput sequencing Amplicons were prepared by 5' and 3' adaptor ligation and RT-PCR using small RNA fractions from inflorescence tissue (containing stage 1-12 flowers) of wt Col-0 plants, mutants with defects in each DCL gene (dcl1-7, dcl2-1, dcl3-1, dcl4-2), and mutants with defects in each RDR gene for which a function has been established (rdr1-1, rdr2-1, rdr6-15). Amplicons from whole seedlings (3 day post-germinations) were prepared from Col-0 and rdr6-15 plants. Small RNA preparations from leaf samples of Col-O that were either uninoculated or inoculated by Pseudomonas syringae pv tomato (DC3000hrcC) for 1 hr and 3 hr were also sequenced.

Posttranscriptional RNA silencing of many endogenous transcripts, viruses, and transgenes involves the RNA-DEPENDENT RNA POLYMERASE6/DICER-LIKE4 (RDR6/DCL4)-dependent short interfering RNA (siRNA) biogenesis pathway. Arabidopsis thaliana contains several families of trans-acting siRNAs (tasiRNAs) that form in 21-nucleotide phased arrays through the RDR6/DCL4-dependent pathway and that negatively regulate target transcripts. Using deep sequencing technology and computational approaches, the phasi  ...[more]
