  We show that in see-saw models of neutrino mass a la SUSY SO(10), the
observed large mixing in atmospheric neutrinos naturally leads to large b-s
transitions. If the associated new CP phase turns out to be large, this SUSY
contributions can drastically affect the CP violation in some of the B decay
channels yielding the beta and gamma angles of the unitarity triangle. They can
even produce sizeable CP asymmetries in some decay modes which are not CP
violating in the standard model context. Hence the observed large neutrino
mixing makes observations of low energy SUSY effect in some CP violating decay
channels potentially promising in spite of the agreement between the Standard
Model and data in K and B physics so far.
