The parton distributions of the nucleon are evaluated dynamically using the assumption that at some low resolution scale the nucleon consists entirely of valence quarks. A simple parametrization of the resulting gluon distribution is presented, for x 10-5 up to Q 2106 GeV2. This gluon distribution is predicted dicted to be much steeper and larger in the very small x region (x<10-2) than usually assumed. Applications to deep inelastic scaling violations and heavy quark (c, b, t) contribution are discussed and presented as well as hadronic heavy quark production at SSC/LHC energies. For example, the bb- production rate at 40 TeV is predicted to be about an order of magnitude larger than that estimated with other gluon distributions so far.
