Analysis of bacterial resistance to Pseudomonas syringae tabaci in Ta-JA1 transgenic tobacco plants. P. syringae (107 colony forming units/ml) was inoculated into the fourth to sixth upper leaves of Ta-JA1 transgenic plants of T2 progeny and the control (BI121) that was transferred with pBI121 vector alone. The infected leaves were collected and the bacterial populations were determined seven days after inoculation. Values are the means of three different experiments, and bars are standard errors. Probability values between the control and transgenic tobacco were estimated by the Student's t-test and significant differences at P0.05 and P0.01 levels are marked by * and **, respectively.
