Root hydraulic conductivity (Lp_r) and aquaporins were investigated in barley seedlings under salt stress of 100 mmol L^<-1> NaCl in hydroponic culture for 24 and 48 h. No reduction in root elongation was observed in stressed seedlings, and more that 75% of root and shoot growth was maintained under salt stress of 100 mmol L^<-1> NaCl. A slight increase in HvPIP2 ; 1 transcript, which was the most abundant of the three aquaporins investigated, was observed. No significant changes in Lp_r and HvPIP2 ; 1 protein were detected. The possible reason for these complicated results and the function of aquaporins in Lp_r under salt stress are discussed.
