We study the evolution of the Stellar Mass-Metallicity Relation and the\nLuminosity-Metallicity Relation by performing numerical simulations in a\ncosmological framework. We find that the slope and the zero point of the\nLuminosity-Metallicity Relation evolve in such a way that, at a given\nmetallicity, systems were ~3 mag brighter at z=3 compared to galaxies in the\nlocal universe, which is consistent with the observational trend. The local\nStellar Mass-Metallicity Relation shows also a good agreement with recent\nobservations. We identify a characteristic stellar mass Mc ~ 10^(10.2) Msun/h\nat which the slope of the Stellar Mass-Metallicity Relation decreases for\nlarger stellar masses. Our results indicate that Mc arises naturally as a\nconsequence of the hierarchical building up of the structure.\n
