Resistance to Pst DC3000 in BSR2-OX Arabidopsis lines. (a) Phenotypic responses to Pst DC3000 inoculation. Three-week-old plants were inoculated with 2 × 108 cfu/mL of Pst DC3000. The wild-type (WT; Col-0) plants died, but the K02919 (a rice-FOX Arabidopsis T2 line; BSR2-OX) and cpr5-2 (control mutant resistant to Pst DC3000) plants remained green. (b) Growth of Pst DC3000 bacteria in plants. Arabidopsis plants at about the 20-leaf stage were inoculated with Pst DC3000 (106 cfu/mL) by dipping, and the numbers of bacteria in the aerial part of the plants were counted after 4 d. The bacteria in 8 replicates were counted and the differences between WT and two independent BSR2-OX lines (K02919 and RT:BSR2-OX#3) were significant according to a t-test (*P < 0.05; **P < 0.01). Error bars represent the standard deviation.
