摘要: Betaine aldehyde dehydrogenase (BADH) cDNA cloned from Atriplex hortensis L. in the plasmid pABH9 containing maize ubiquitin promoter and bar gene was transferred into wheat (Triticum aestivum L.) by microprojectile bombardment with 4.1% of average frequency of transformation. From 300 young embryo calli bombarded with the plasmid, 24 transgenic plants were obtained showing BADH gene integration by both PCR and Southern blotting analysis. Among the 24 transgenic plants, 13 exhibited higher BADH activity than the control. Some transgenic plants grew normally with healthy roots on the medium containing 0.7% NaCl while the control plants had very poor roots and finally died.
