谷胱甘肽还原酶是植物体内一类重要的抗氧化酶.以湘莲叶片为材料,根据其它植物谷胱甘肽还原酶(GR)氨基酸保守区序列设计简并引物,通过RT—PCR扩增到1个408bp大小的cDNA片段(Genbank注册号为AY781786),5、和3 RACE获得5、和3、端序列,全长1580bp,包含一个1140bp的开放阅读框架,编码380个氨基酸,与其它植物谷胱甘肽还原酶氨基酸序列的同源性在77%~92%之间.
穀胱甘肽還原酶是植物體內一類重要的抗氧化酶.以湘蓮葉片為材料,根據其它植物穀胱甘肽還原酶(GR)氨基痠保守區序列設計簡併引物,通過RT—PCR擴增到1箇408bp大小的cDNA片段(Genbank註冊號為AY781786),5、和3 RACE穫得5、和3、耑序列,全長1580bp,包含一箇1140bp的開放閱讀框架,編碼380箇氨基痠,與其它植物穀胱甘肽還原酶氨基痠序列的同源性在77%~92%之間.

According to the amino acid sequence of glutathione reductase (GR) in other plants, a pair of degenerate primers are designed for the isolation of middle segment of GR gene from Nelumbo nucifera Xiang lotus and a 408-bp segment is amplified by RT-PCR(Accession number. AY781786). Then 5'cDNA sequence and 3'cDNA sequence of the gene are obtained by 5'RACE and 3RACE. By assembly, a complete 1580bp sequence is obtained, including an open reading flame, The sequence shares 77-92% similarity at amino acid level to the sequences from Oryza sativa, Zea mays, Vitis vinifera, Zinnia elegans, Nicotiana tabacum , Soybean and Glycine max.
