摘要: alpha-Linolenic acid (ALA, C 18:3(Delta 9,12,15)) has many important biological functions. omega-3 Fatty acid desaturase (FAD3), existing in cytosolic and plastidic compartments of higher plants, catalyzes linoleic acid (LA) desaturation to produce ALA. GmFAD3A-2 and GmFAD3C genes encoding cytosolic FAD3 from Qihuang 29 soybean were cloned and inserted into p416 vector and expressed in K601 yeast strain. Gas chromatography showed that the transformed yeast strains could produce ALA. The ALA accumulation levels for the strains transformed with GmFAD3A-2 or GmFAD3C genes were 0.77 +/- 0.1 and 4.13 +/- 0.4% of total fatty acids, respectively, while, as compared with that of the control, the contents of LA decreased from 14.34 +/- 0.8 to 10.93 +/- 0.0 and 7.85 +/- 0.1%, respectively, implying that the GmFAD3C enzyme is more vigorous or stable, than GmFAD3A-2.
