It is shown that the conductance of a weakly disordered Luttinger-liquidquantum wire connected to non-interacting leads is affected byelectron-electron interactions in the wire. This is in contrast to the case ofa perfect wire the conductance of which is given by $e^2/h$ regardless ofinteractions in the wire. The disorder-induced correction to the conductancescales with temperature and/or the wire length, the scaling exponent beingdetermined only by the interaction strength in the wire. These results explainrecent experiments on quasi-ballistic GaAs quantum wires.
