      abstract     = {In this article, we present the derivation of
                      Landau-Khalatnikov-Fradkin (LKF) transformation for the
                      quark propagator in an arbitrary $SU(N)$ gauge theory.
                      Working in the system of covariant gauges, we derive
                      transformation law by making perturbative expansions till
                      ${\cal O}(g_s^6)$ and, for some terms, till ${\cal
                      O}(g_s^8)$. The corresponding transformation for the abelian
                      case of quantum electrodynamics is trivially recovered by
                      setting the color factors $C_F=1$ and $C_A=0$. Finally, we
                      study the implications of this QCD transformation for the
                      quark-antiquark condensate, multiplicative renormalizability
                      of mass less quark propagator and its relation with the
                      quark-gluon vertex at one loop order.},
