Cercospora infected leaf

Sugar beets currently supply about half of the United States' sugar (sucrose), and when processed it is of course identical to that of sugarcane. The thrust of this program is to control disease and/or improve disease resistance to microbial pathogens using genetic modification.

Resistant plant

Targeted are bacteria, namely, Erwinia (or Pectobacterium) betavasculorum that causes root rot disease and fungi, specifically, Cercospora beticola that causes leaf spot disease.

A better understanding of the molecular basis for both disease resistance and pathogenesis is being sought using molecular approaches including but not limited to genomics. Transgenic plants are employed to look at potential new mechanisms of effective disease prevention.
