In Figure 1A, two nucleotides in the stem loop hairpin of B. rapa/B. napus were inadvertently mislabeled. Position 22 is the first nucleotide (U) of miR824, indicated in red, and position 588 is the first nucleotide (C) of miR824*, indicated in blue.
On page 2424, line 6, paragraph 2, of the section “The miR824/AGL16 Pathway Functions in the Satellite Meristemoid Lineage” should read as follows: Recent evidence suggests that this signal, which requires TOO MANY MOUTHS (TMM) for its perception, is a peptide encoded by EPIDERMAL PATTERNING FACTOR1 (EPF1) or is processed by STOMATAL DENSITY AND DISTRIBUTION1 (SDD1) (Hara et al., 2007).
