Salinity response of
in tomato WT plants. Analysis of SlIPT3 and SlIPT4 expression levels in tomato WT roots (A), young leaves (B) and old leaves (C) in response to salt stress (150 mM NaCl). Actin and GAPDH were used as internal controls for normalization of SlIPT3 and SlIPT4 transcript levels. Data represent means and SD of two replicates. *statistically significant difference from time 0 h (unpaired two-tailed Student’s t-test, p ≤ 0.05). **statistically significant difference from time 0 h after Šidák correction for testing of multiple time points (multiple unpaired two-tailed Student’s t-test, overall α = 0.05, individual p ≤ 0.01).
