Expression of SlHUB1 and SlHUB2 in responses to pathogens and defense signaling-related hormones. Four-week-old plants were inoculated by spore suspension of B. cinerea (a), vacuum-infiltrated by suspension of Pst DC3000 (b) or treated by foliar spraying with 1 mM SA, 100 μM MeJA, 100 μM ACC solutions or sterilized distill water as a control (c). Leaf samples were collected at indicated time points after treatment. Relative expression was shown as folds of the actin transcript values. Data presented are the means ± SD from three independent experiments and different letters above the columns indicate significant differences at p < 0.05 level
