S-Nitrosylation at Cys-32 enhances plants resistance to oxidative stress. A, Ten-day-old seedlings germinated and grown on one-half-strength Murashige and Skoog agar plates with various combinations of 50 μm SNP and 0.2 μm paraquat (PQ). Scale bars = 1 cM. B, A quantitative analysis of the relative length of the primary roots (n = 30 seedlings for each genotype). The relative root length of Col-0 seedlings grown under normal growth condition is set at 1.0. C, The ratio of the primary root length shown in B. Error bars in C and D = sd from three independent experiments (biological replicates). Two-tailed Student’s t test; **, P < 0.01; and ***, P < 0.001.
