Title
Effects of ozone on wild type and transgenic tobacco
Author
Abstract
Tocopherol cyclase (TC, encoded by gene VTE1) catalyzes the penultimate step of tocopherol synthesis. In this study we used wild type and transgenic tobacco plants overexpressing VTE1 from Arabidopsis to examine the role of tocopherol in ozone sensitivity. Wild type plants responded to an 4-h exposure to 300 nmol mol−1 ozone by severe leaf necrosis while the transgenic lines exhibited limited injury. Compared with the wild type, VTE1-overexpressing plants had lower increase in hydrogen peroxide, malondialdehyde contents and ion leakage, and lower decrease of net photosynthetic rate 48 h following the ozone exposure. Transgenic plants also better maintained the structural integrity of the photosynthetic apparatus.
