One loop corrections to the coupling of the Reggeized gluon to quarks are calculated in QCD. Combining this result with the known corrections to the gluon-gluon-Reggeon vertex, we check the self-consistency of the representation of the amplitudes with gluon quantum numbers and the negative signature in the t channel in terms of the Regge pole contribution.
