Parton-shower event generators that go beyond the collinear-orderingapproximation at small x have so far included only gluon and valence quarkchannels at transverse momentum dependent level. We describe results of recentwork to include effects of the sea-quark distribution with explicit dependenceon the transverse quark-momentum.This sea-quark density is then applied to thedescription of forward Z -production. The qq*->Z matrix element (with oneoff-shell quark) is calculated in an explicit gauge invariant way, making useof high energy factorization. The kT-factorized result has been implementedinto the CCFM Monte-Carlo CASCADE and a numerical comparison with the qg*->Zqmatrix element has been carried out.
