摘要
将从极端耐盐的假单胞杆菌中克隆得到的3个基因 ,即转录调控因子基因、NADH脱氢酶Ⅱ基因和磷酸甘油磷酸酯酶基因转入淡水蓝藻Synechococcussp.PCC7942中 ,使受体藻对NaCl的耐受性从低于2.5%显著提高到4.5% ,进一步证明了这3个基因确实与生物的耐盐性密切相关。本实验为进一步培育耐盐经济作物奠定了基础。
Three salt-tolerant-related genes, transcriptional regulator gene, NADH dehydrogenase II gene and phosphoglycolate phosphatase gene,which are cloned from Pseudomonas xiamenensis, a species of halophilic bacterium, have been transferred as a gene cluster to cyanobacterium Synechococcus sp. PCC 7942. As a result, the NaCl resistant level of the microorganism has been obviously raised from less than 2.5 % to 4.5 %. It shows that the three genes are close correlative to the ability of salt-resistance. This experiment provides a potential possibility for cultivation of salt-resistant economic plants.
