Overexpressing OsVQ14 and OsVQ32 enhanced rice resistance to Xoo. The asterisks “**” or “*” indicate a significant difference between transgenic plants and wild type (WT; Zhonghua 11) plants at P < 0.01 or P < 0.05, respectively. N, negative siblings segregated from the T₁ families. a and b The enhanced resistance of the transgenic plants to Xoo is associated with OsVQ14 expression (a) and OsVQ32 expression (b) in two T₁ families. Bars represent mean (3 to 5 leaves from one plant for lesion area, and 3 replicates for expression level) ± standard deviation (SD). c Analysis of the Xoo growth in leaves of OsVQ14-oe and OsVQ32-oe plants. Bars represent mean (3 leaves from 3 positive plants) ± SD. The significant difference was detected between transgenic plants and WT with the same treatment. cfu, colony-forming unit. d Analysis of the response of OsVQ14-oe and OsVQ32-oe plants to different Xoo strains. Bars represent mean (3 plants, with each plant having 3 to 5 leaves for lesion area) ± SD
