SOD1 and infection: Moreover, the Cu-miRNAs miR398, which targets two Cu/Zn superoxide dismutases (CSDs), the cytosolic CSD1 and CSD2, was down-regulated by infection in S null 2-2890 tissues, in comparison to the R ones (FCs = −77.29 and −55 for spikelet and rachis, respectively; MT2 from miRNA-Seq experiment; Supplementary Data Sheet 2-Sheets 1, 2).
