Figure 2. northern blots of miR167 and miR165/166 from total RNA or AGO1 immunoprecipitates from hen1–8 and hen1–8 heso1–1 inflorescences. Note that the Col (wild type) samples only serve as a size reference; RNA from seedlings was used and was not in the equivalent quantity as the hen1–8 or hen1–8 heso1–1 samples. The bands representing miRNAs of the wild-type size are indicated by asterisks. The arrows above and below the asterisks mark bands that represent 3′ uridylated and 3′ truncated species, respectively.
