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. 4
and
Table 2
). It has been shown that K
+
transporters involved in K
+
uptake by roots and its long-distance transport are expressed
under drought conditions
