Phenotype of pepr mutant plants subjected to salinity stress. (Top) Images of representative plants after each peptide/salt treatment. (Bottom) Chlorophyll content per fresh weight (FW) in plants after each peptide/salt treatment. Seven-day-old single or double receptor mutant plants were pretreated with 100 nM of a peptide fragment for 3 d (peptide pretreatment) followed by a combined treatment with the peptide plus 150 mM NaCl. All treatments were carried out in liquid culture. Plants were grown for 10 d and chlorophyll content was subsequently assessed. The presented data represent the average of three biological replicates.
