• Aquaporins are membrane proteins facilitating the membrane transport of water and low molecular weight compounds. Recent studies have indicated that aquaporins are involved in cellular tolerance mechanisms under low temperature stress in plants and insects. Critical roles of aquaporins in cold tolerance and the influence of H_2O_2 were suggested in the cucumber and figleaf gourd. Reduction of water uptake was observed in rice under chilling stress, in which the down-regulation of aquaporin expression and probable inactivation of aquaporins were involved. Glycerol and water transport by aquaporins was investigated, and revealed to be essential for freezing tolerance in insect cells.
