Early responses in plant roots. (A) Overview of H₂O₂ production in roots of plants exposed to salt stress. Values are calculated with respect to the control at each time-point. Data are mean ± SD of 10 biological replicates and three technical replicates. (B) SERF1 expression profile at different time-points in roots. (C,D) Expression profile of genes involved in perception, signaling and response to salt stress in Baldo (C) and Vialone Nano (D) roots. Data are expressed as mean ± SD of three biological replicates and nine technical replicates. Letters represent p-value < 0.01 with respect to the control (a) or to the other variety (b).
