| Outline of Final Research Achievements |
Pathogens acquire sugars as a main carbon source from host plants. However, it remained unknown whether plants attempt to prevent pathogen’s sugar gain, for example, by retrieving extracellular sugars. Here, we found that Arabidopsis plants lacking sugar transporters were more susceptible to pathogenic bacteria, and sugar uptake activity is enhanced during immune activation in Arabidopsis. In addition, we demonstrated that the activity of STP13, a sugar transporter, was regulated via phosphorylation by a pathogen-recognition receptor complex. In this study, we revealed that plants exhibit a defense strategy using sugar transporters to reduce extracellular sugars during pathogen infection.
