  We study the effects of light gluinos with mass below about 1 GeV on the
nucleon parton densities and the running of alpha_(S). It is shown that from
the available high-statistics DIS data no lower bound on the gluino mass can be
derived. Also in the new kinematical region accessible at HERA the influence of
such light gluinos on structure f unctions is found to be very small and
difficult to detect. For use in more direct searches involving final state
signatures we present a radiative estimate of the gluino distribution in the
nucleon.
