Implications of a class of neutrino mass matrices with texture zeros for   non-zero $\theta_{13}$
  A class of neutrino mass matrices with texture zeros realizable using the group $Z_3$ within the framework of type (I+II) seesaw mechanism naturally admits a non-zero $\theta_{13}$ and allows for deviations from maximal mixing. The phenomenology of this model is reexamined in the light of recent hints for non-zero $\theta_{13}$.
