SlHyPRP1-RNAi (Ri) transgenic tomato plants have significantly improved salt stress tolerance compared with the wild type (WT) and HyPRP1 overexpressed (OE) transgenic plants. (A) Growth of transgenic and WT plants under non-stress (upper panel) and salt stress (bottom panel) in the field. (B,C) Significant differences in relative growth rates along transgenic and WT lines under salt treatment and no stress control conditions, respectively. Error bars indicate ± SE of the means (*) significant difference at P < 0.05. (D) The chlorophyll content of salt-treated and untreated leaves from wild-type (WT) and RNAi (Ri) plants. Error bars indicate ± SE of the means and (**) indicates significant difference at P < 0.01.
