The effect of ddl-1 on small RNA profile

DAWDLE (DDL) is a conserved forkhead-associated (FHA) domain-containing protein that plays essential roles in development and immunity. It was found to act in the biogenesis of microRNAs (miRNAs) and endogenous small interfering RNAs (siRNAs), which regulate gene expression at transcriptional and/or post-transcriptional levels. However, its global effect on miRNA accumulation still is not known. To determine the global effect of DDL on the accumulation of miRNAs and siRNAs, we compared the small RNA profile in ddl-1 with that in WS (Wild-type, WT). Small RNA libraries prepared from inflorescences of ddl-1 and WS was subjected to Illumina deep sequencing analyses. The results show that many miRNAs and siRNAs were reduced in abundance in ddl relative to WS in two biological replicates We compared the small RNA profile in ddl-1 with that in WS (Wild-type, WT) non coding RNA deep sequencing
