Intervention effect At anthesis, elevated CO2 and temperature maintained better water status than current conditions.
Intervention effect Elevated CO2 and temperature reduced stomatal conductance.
Intervention effect Elevated CO2 and temperature slowed plant water flow.
Mechanism Leaf HvPIP2;1 and HvTIP1 ; 1 were interpreted as key regulators of barley water flow.

Intervention effect Under future combined conditions, anthesis drought decreased leaf relative water content against current conditions.
Intervention effect Prior drought did not prime barley water status for a later drought.
