For two solutions of the WDVV equations that are related by the inversionsymmetry, we show that the associated principal hierarchies of integrablesystems are related by a reciprocal transformation, and the tau functions ofthe hierarchies are related by a Legendre type transformation. We also considerrelationships between the Virasoro constraints and the topological deformationsof the principal hierarchies.
