Exogenous glucose positively enhances PTI. a Callose deposition in Col-0 leaves infiltrated with water or glucose (glc) 24 h before inoculating with 100 uM flg22. b Callose deposition in hxk1 leaves as described in (a). c PR1 accumulation in Col-0 leaves infiltrated with glucose. d PR1 accumulation in hxk1 leaves infiltrated with glucose. Coomassie Brilliant Blue (CBB) staining was used to ensure equivalent loading. Experiments were repeated three times
