<i>hen2</i> mutants accumulate short transcripts derived from mRNA genes.

<p>qRT-PCR analysis. A diagram of the genomic locus indicated by the respective AGI number is shown at the top of each panel. Annotated mRNA genes are represented as arrows with dark blue boxes for the CDS, light blue boxes for 3′ and 5′ UTRs, and a light blue line for introns. Red bars above the diagram represent probes detected in the tiling analysis. Green arrows above or below the diagram depict the location of qRT-PCR primers. The corresponding qRT-PCR results for each primer pair are given as fold-change relative to WT in the histograms below each diagram. <i>mtr4-1</i> in red, <i>mtr4-2</i> in orange, <i>hen2-2</i> in light green, <i>hen2-4</i> in dark green, <i>RRP41</i> control in light grey, <i>RRP41</i> RNAi in dark grey. Error bars = SD in three biological replicates.
