  A self-interacting polymer can undergo an orientational ordering transition,
depending on the magnitude of the nematic interaction. The effect of embedding
such a polymer into a flexible surface on this transition is studied on the
mean-field level. Renormalized values of the elastic constants of the
``dressed'' surface are derived as functions of the orientational order
parameter of the polymer chain. In the disordered state the surface tension and
curvature modulus remain scalars but depend on the surface coverage of the
embedded polymer. In the nematic state there is a symmetry breaking transition
leading to anisotropic elastic constants. At a sufficiently large nematic order
parameter the effective surface tension in the direction perpendicular to the
nematic axis can become negative, leading to tubulization of the embedding
surface.
