- Abstract
Transgenic Italian ryegrass plants expressing the betaine aldehyde dehydrogenase gene of zoysiagrass (ZBD1) were produced via particle bombardment of embryogenic calluses. Although the growth of both non-transgenic and transgenic plants expressing ZBD1 was inhibited under salt stress, isolated tillers of the transgenic plants showed better re-rooting ability in vitro in the presence of 300 mM NaCl. Chlorophyll fluorescence values of the transgenic plants declined under salt stress, but were significantly higher than those of non-transgenic plants under salt stress, indicating the improved salt stress tolerance of transgenic plants.
