摘 要: 以玉米F1减弱表达基因的cDNA片段为探针,从建立的玉米cDNA的文库中分离到相应的cDNA克隆.经测序和序列同源分析证明,该cDNA编码6-磷酸果糖-2-激酶/果糖-2,6-二磷酸酶,其氨基酸序列与人类、大鼠、牛和鸡等动物肝脏相同基因对应区段的相似性分为为65.7%,63.4%,63.7%和61.2%. A cDNA clone designated ZH03 was isolated from the constructed maize seedling cDNA library with a cDNA fragment underexpressed in hybrid maize probe. Sequence analysis shows that ZH03 cDNA coding for 6phosphofruco2kinase/fructose2,6bisphosphatase, its protein has 657%,644%, 637% and 612% amino acids similar with the human, rat, bovine and chichen liver isoform respectively in the cloned fragment.
