High aluminum was added at 12 dpi for 7 days. The significant expression ratios (Alt:control) are the average of normalized signal intensity values from three biological replicates of miRNA-macroarrays. Names of non-conserved miRNAs, reported previously (Arenas-Huertero et al., 2009; Lelandais-Brière et al., 2009; Valdés-López et al., 2010), include abbreviation of the legume species where these were first annotated: pvu, Phaseolus vulgaris, gma, Glycine max, and mtr, Medicago truncatula. For ratios lower than 1 (miRNAs down-regulated in stress), the inverse of the ratio was estimated and the sign was changed.
