a The H2O2 content in the shoot and root of 7-day-old wild type XS134 plants cultured hydroponically under HP or LP conditions for 2 days. b–e, The morphology (b), biomass (c), and Pi concentrations in shoot (d) and in root (e) of wild type XS134 plants treated with 1 mM of H2O2 or 10 µM KI cultured hydroponically under HP or LP conditions for 28 days. f, g The H2O2 content in shoot (f) and root (g) of the 7-day-old wild type XS134, rboh-D, rboh-H, and rboh-DH plants cultured hydroponically under HP or LP conditions for an additional 2 days. h–k The morphology (h), biomass (i) and Pi concentrations in shoot (j) and root (k) of wild type XS134, rboh-D, rboh-H, and double mutant rboh-DH plants cultured hydroponically for 28 days under HP or LP conditions. Bar = 10 cm in b and g. DW dry weight, FW fresh weight. Data are means ± SD (n  =  5 replicates, 3 seedlings per replicate for a, d, e, f, g, j, and k; n  =  3 replicates, 10 seedlings per replicate for c and i). The P-value was generated by a two-sided Student’s t test. Source data are provided in the Source Data file.
