Silencing of CaSLP by virus-induced gene silencing (VIGS) decreases drought tolerance in pepper. A Phenotype of CaSLP-silenced and control (TRV, tobacco rattle virus) plants before and after 15 d of drought treatment. Plants were treated under water deficit conditions for 15 days, then rewatered for 3 days. B, E Histochemical staining of 3,3’-diaminobenzidine (DAB) and nitro blue tetrazolium (NBT) was performed to detect the accumulation of H2O2 and O2.− levels, respectively. C, F H2O2 and O2..− contents. G Chlorophyll contents of the CaSLP-silenced and control plants before and after 15 d of drought treatment. H Photomicrographs of stomata from the CaSLP-silenced and control plants. I The stomatal aperture was analyzed under the microscope. J Stomatal density K Water loss rate of the CaSLP-silenced and control plants. Error bars represent ± SD (n = 3). Asterisks represent a significant difference between CaSLP-silenced and control plants under the same condition (*, P < 0.05; **, P < 0.01)
