In this paper we study the anisotropic universe using Noether symmetries in modified gravity. In particular, we choose a locally rotationally symmetric Bianchi type-I universe for the analysis in 
gravity, where R is the Ricci scalar and 
is the Gauss–Bonnet invariant. Firstly, a model 
is proposed and the corresponding Noether symmetries are investigated. We have also recovered the Noether symmetries for f(R) and 
theories of gravity. Secondly, some important cosmological solutions are reconstructed. Exponential and power-law solutions are reported for a well-known model, i.e., 
. Especially, Kasner’s solution is recovered and it is anticipated that the familiar de Sitter spacetime giving 
cosmology may be reconstructed for some suitable value of n.
