miRNA-like RNAs from the miR447a precursor. (a) The precursor fold-back structure and sequencing reads mapped to miR447a.1 (that is, miR447a) and the individual miRNA-like RNAs. For clarity, miR447a.3* and miR447a.1* are indicated though the numbers of reads mapped to them were below the cutoff threshold of 5. (b) Distribution of sequencing reads along the precursor. (c) Expression of miR447a.1 and miR447a.3 in various Arabidopsis mutants of small RNA pathways. (d) Expression of miR447a.3, miR447a.1, and miR447a.2-3p under the challenge of three Pst strains (hrcC, avrRpt2 and EV) and in a mock control at 6 and 14 hpi.
