• Both root and shoot of barley seedlings showed continuous growth at night as well as in the daytime. Root hydraulic conductivity (Lp_r) was monitored, and high Lp_r values were recorded at night. For revealing the molecular mechanism, the presence of an aquaporin HvPIP2;1 in barley roots was investigated. The accumulation of the HvPIP2;1 transcript was mostly observed from the evening to the middle of the night. HvPIP2;1 protein was most abundant around midnight. As for tissue localization, HvPIP2;1 protein was abundant in cells involved in water transport. These results suggested the possible involvement of HvPIP2;1 in the mechanism of water transport in roots.
