The low classical instability strip crosses the Main Sequence in the domain
of A and F stars. This domain is known for the large variety of stars showing
specific characteristics in terms of chemical surface compositions, pulsational behaviours, magnetic fields, rotation rates. Stellar seismology has long been seen as a very appropriate tool for improving our understanding of stars in this domain and disantangle the respective role on their structure and evolution of physical processes like fast rotation, chemical diffusion, magnetic field. The recent advent of space observations, with MOST, CoRoT and now Kepler, is schedding a new light on this problem. We will try here to illustrate this new vision with a selection of such new data and interpretation works.
