Leptosphaeria biglobosa inhibits the production of sirodesmin PL by L. maculans
Fortune, James; Bingol, Evren; Qi, Aiming; Baker, Daniel; Ritchie, Faye; Karandeni Dewage, Chinthani Shanika; Fitt, Bruce; Huang, Yongju (2022-11-29)BACKGROUND: Phoma stem canker is caused by two coexisting pathogens, Leptosphaeria maculans and L. biglobosa. They coexist because of their temporal and spatial separations, which are associated with the differences in ... -
