From: OsVPE2, a Member of Vacuolar Processing Enzyme Family, Decreases Chilling Tolerance of Rice
Accumulation of H2O2 and O2- in seedings under chilling stress. A DAB staining and B NBT staining of leaves before treatment or upon chilling exposure. C Quantitative measurement of total H2O2. D Quantitative measurement of total O2- content. Bar, 0.75 cm. Data are means ± SD (n = 3), Different letters indicate significant differences among all the materials (WT, OsVPE2-knockout mutants: osvpe2-1 and osvpe2-2; the overexpression lines of OsVPE2: OE-1 and OE-2) under the control and chilling stress treatments by two-way analysis of variance (p < 0.05)
