Obligate biotrophic fungal pathogens establish long-term feeding relationships with their plant host, during which they siphon sugars from host cells through haustoria. The Arabidopsis hexose transporter, STP13 (sugar transport protein 13), was previously shown to confer resistance against hemi-biotrophic and necrotrophic pathogens by limiting sugar flux towards these pathogens. By contrast, expression of Lr67res, a […]
