[Saline tolerance white clover transformed with the betaine aldehyde dehyrogenase gene by Agrobacterium tumefaciens].

ABSTRACT

The white clover has been transformed with the Betaine Aldehyde Dehydrogenase (BADH) gene cloned from Atriplex hortensis by Agrobacterium tumefaciens. The relative electronic conductivity of the transgenic plants under 1% NaCl stress for 48 hours was about 20%, less than the control plant's relative electronic conductivity (more than 40%), these showed the cell membrane of the transgenic plants has been less injured than control plants under salt stress. The other experience showed that the transgenic plant could grow well in water culture included 0.5% NaCl for more than two weeks, but the control plants could not.
