However, the results obtained with the cultivar Olimpia grown in
the hydroponic liquid medium with an adequate level of K+
clearly show that the increase in K+
transport in the root in response to
water stress was not dependent on root K+
starvation (Fig. 4andTable 2). It has been shown that K+
transporters involved in K+ uptake by roots and its long-distance transport are expressed
under drought conditions
