Bacterial growth in plants. Five-week-old Arabidopsis plants were inoculated with Pst DC3000 by dipping in a bacterial suspension (10⁶ cfu/mL), and the numbers of bacteria in the aerial part of the plants were counted after 3 days. Bars indicate the SD (n = 4). (a) The differences in bacterial count between Col-0 (or vector controls) and AK070024:OX plants are significant at 5% (*) by t-test. Col-0, wild type; vc, vector control. (b) The differences in bacterial counts in plants between Col-0 and the selected Pst DC3000-resistant transgenic Arabidopsis lines are significant at 5% (*) or 0.1% (***), respectively. RT:AK070024:OX#1 is the same retransformed line as that used in Fig. 1.
