  The global and electromagnetic gyrokinetic particle-in-cell code ORB5 is
employed to investigate the self-consistent interactions between Alfv\'en modes
(AM) and ion temperature gradient (ITG) turbulence in a magnetically confined
plasma. Here, an axisymmetric magnetic equilibrium with reversed shear and
large aspect ratio is considered. An AM with toroidal mode number n=5 is driven
unstable by introducing a population of suprathermal ions. Once the AM
saturates in the presence of the fully developed turbulence, the ion heat flux
is dominated by the AM and its main harmonics. ITG-induced transport is found
to also be enhanced in the presence of the unstable AM.
