Our data provides insights into the responses of sugar beet to infection by A. cochlioides. Global reactions to A. cochlioides infection consist of induction of secondary metabolites and flavonoid biosynthesis and an up-regulation of chalcone synthases (CHS), auxin-binding proteins, glutathione S-transferases (GSTs) and germin-like proteins (GLP). The gene discussed is LYST; the disease is infection.
