PpSnRK1α overexpression lines had higher SnRK1 activity and increased salt tolerance. a Relative expression level of SnRK1 (PCR was performed using homologous and specific fragments of PpSnRK1 (Prunus persica) and SlSnRK1 (Solanum lycopersicum) between WT plants and PpSnRK1α overexpressing plants). This picture was cropped for simplicity and intuitiveness, the original pictures were in Additional file 1b Determination of SnRK1 activity c REC of the WT and PpSnRK1α overexpression lines d Evans blue stain. Note: in b and c, the data are represented as means ± standard error (S.E.) of three biological replicates
