TGFBI and infection: More interestingly, the O•2− concentrations markedly decreased upon Guy11 infection in OX398b, csd1, csd2 and sodx lines, but only slightly changed in ccsd and target gene overexpressing lines (Figs 5b, S5a,c), suggesting that overexpression of miR398b, or mutations in CSD1, CSD2 and SODX positively regulated the blast infection‐promoted conversion of O•2− to H2O2, whereas overexpression of target genes had little effect on the conversion process.
