Sumario:We use a sample of galaxy groups in SDSS data to study their brightestgalaxies (BGG), separating groups according to their large scale environment. The statistical properties of the BGG depend on the surrounding environment on large scales, characterized by the high density peaks within Future Virialized Structures (FVS). We also find that the luminosity, colour, stellar masses and concentration index of the BGG hosted by groups in superstructures are different, with statistical significance, from the corresponding properties of BGG hosted by groups elsewhere. Moreover, this signal is strongly dominated by disk-type galaxies.<p>The results reveal connections between the large scale environment and the accretion process onto the brightest group galaxies.</p>
