Measurement of callose deposition following flg22 treatment and after. Hpa infection using CalloseMeasurer. (A) The number of callose deposits following flg22 treatment was significantly greater on Arabidopsis Col-0 cotyledons than on cotyledons of fls2 mutant plants. (B) The spreading network of callose on Hpa infected leaves was significantly longer on eds1 mutant leaves than on Arabidopsis Col-0 leaves. Asterisks indicate p-values < 0.05 (*) and < 0.001 (***).
