Abstract
We use a Gr\"obner basis technique first introduced by Knutson, Miller and Yong to study the interplay between properties of a graph and algebraic properties of the toric ideal that it defines. We first recover a well-known height formula for the toric ideal of a graph and demonstrate an algebraic property that can detect when a graph deletion is bipartite. We also bound the chromatic number using information about an initial ideal of .
