Overexpression of CaSLP confers enhanced drought tolerance to transgenic Arabidopsis. A-B The phenotype of transgenic and wild-type (WT) plants before and after 10 d of drought treatment. Plants were treated under water deficit conditions for 10 d, then rewatered for 3 d. C-E Relative electrolyte leakage (C), and Malondialdehyde (MDA) content (D), Chlorophyll content (E) of the transgenic and WT plants before and after the drought treatment. Values are means ± SD (n = 3). Asterisks show a significant difference between the transgenic lines and WT under drought stress (*, P < 0.05; **, P < 0.01)
