Extended Data Fig. 9: UMP1^R2115 enhances rice resistance to multiple pathogens and H₂O₂ accumulation, which is compromised by overexpression of OsAPX8 or OsCatB.

a-f, Disease phenotype, lesion length, and H₂O₂ quantification of leaves from TP309, UMP1^R2115-1/13, and ko-11 plants infected with R. solani (a-c) or Xoo (d-f). g-l, Disease phenotype, lesion length, and H₂O₂ quantification of leaves from OsAPX8-overexpressing lines in UMP1^R2115-1 background infected with R. solani (g-i) or Xoo (j-l). m-r, Disease phenotype, lesion length, and H₂O₂ quantification of leaves from OsCatB-overexpressing lines in UMP1^R2115-1 background infected with R. solani (m-o) or Xoo (p-r). For R. solani assay, disease phenotype and lesion length were recorded at 2 days post inoculation (dpi), while H₂O₂ quantification was performed at 1 dpi. For Xoo assay, disease phenotype and lesion length were recorded at 14 dpi, while H₂O₂ quantification was performed at 2 dpi. Values are mean ± s.d. (n = 5 biological replicates for b, h, n and 3 biological replicates for c, f, i, l, o, r). P values were determined by two-sided unpaired t-test, compared to TP309 (b, c, e, f) or null segregants (h, i, k, l, n, o, q, r).
