In this Letter, we study behaviors of dark energy in the form of perfect fluid and mesonic scalar field for Marder space-time which is anisotropic and homogeneous in f(R) gravity. Exact solutions of the modified Einstein field equations in f(R) gravity are obtained by using anisotropic features of Marder space-time. We do not make any assumptions about f(R) function while we are solving f(R) equations. We have investigated dark energy behaviors in f(R) gravity. We have concluded that dark energy in our model behaves like phantom type. Also we have concluded that mesonic scalar field transforms to another matters into time. In our solutions, obtained f(R) functions existed by dark energy and mesonic scalar field are same like general one accepted in the literature. Furthermore, physical and kinematical quantities are examined for two matters, separately. Finally obtained solutions are discussed.
