Analysis of resistance to tobacco mosaic virus (TMV) in Ta-JA1 transgenic tobacco plants. The fourth to sixth leaves from the top of Ta-JA1 transgenic plants of T2 progeny and the control (BI121) that was transferred with pBI121 vector alone were infected with TMV. TMV resistance shown by transgenic tobacco plants was measured by ELISA absorbance values at 405 nm (A405) 10 day post 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.
