Salicylic acid improves salinity tolerance in Arabidopsis by restoring membrane potential and preventing salt-induced K+ loss via a GORK channel.

Adding 100mM NaCl to the bathing medium resulted in a highly significant membrane depolarization ( Fig. 6 ); however, a 20 mV difference between SA-untreated and -pretreated plants was maintained throughout the measurement period ( Fig. 6 ).
