Aquaporins are members of the major intrinsic protein superfamily of integral membrane proteins which enable the transport of water, glycerol, and other solutes across membranes in various organisms. In microorganisms, the physiological role of aquaporins is not yet defined. We found a clear correlation between expression of the Candida albicans aquaporin-encoding gene AQY1 and freeze tolerance. A connection with the function for the aquaporin in the natural environment of C. albicans is, however, not obvious.
