Stabilization of miRNA161 and miRNA173 by AGO1 under salt stress conditions. A, Northern-blot analyses of miRNA161* and miRNA173* in response to salt stress. B, The enrichment of miRNA161 and miRNA173 in AGO1-containing complexes (RNA IP during salinity stress). The data are presented as the mean ± sd (n = 3) % of input during stress and control conditions. C, The fold change of miRNA161 and miRNA173 in wild type (Ler) and the ago1-11 mutant in stress conditions. The values obtained by northern hybridization are presented in the chart as the mean ± sd (n = 3) fold change between stress and control conditions. Values were normalized to the U6 level; * t test P value ≤ 0.05.
