The majority of siRNAs deriving from this npcRNAs are 24 nt long and map to both DNA strands of the npcRNA region, suggesting that these npcRNAs correspond to 24-nt-small RNA precursors. Expression analysis in different organs revealed that npc351 is enriched in stems. Whereas the npc375 and npc523 levels appeared unchanged in the rdr2 rdr6 double mutant, the npc34 and npc351 were up-regulated in both seedlings and flowers of rdr2 rdr6 (Fig. 1, right panel), suggesting that RDR2 or RDR6 produces a dsRNA from these npcRNAs, consistent with small RNA production from both DNA strands of these loci. |
