  In minimal supersymmetric model with a light Higgs sector, explicit CP
violation and most general flavor mixings in the sfermion sector, integration
of the superpartners out of the spectrum induces potentially large
contributions to the Yukawa couplings of light quarks via those of the heavier
ones. These corrections can be sizeable even for moderate values of tan(beta),
and remain nonvanishing even if all superpartners decouple. Then Higgs boson
couplings to light quarks assume spectacular enhancements; in particular,
couplings to down and strange quarks become degenerate with that to the bottom
quark. There arise strikingly non-standard effects that can show up in both
Higgs boson searches and FCNC observables.
