摘要
月桂酸是在清洁用品和医药产品中有重要用途的中链脂肪酸。椰子中富含月桂酸特异的溶磷脂酸酰基转移酶基因,克隆该基因在油菜中表达若可获得含月桂酸的油菜新种质,将具有良好的应用价值。为获得脂肪酸成分改良的油菜种质资源,从椰子胚乳中克隆出该基因并构建35S驱动的植物表达载体,通过农杆菌介导法转化油菜子叶柄,在获得的约20株的转化苗中已鉴定有6株转化植株。
Laural acid is an important medium-chain fatty acid in cleaning supplies and pharmaceutical products.Coconut has abundant Lyso-phosphatidic acid acyltransferase(LPAAT) genes with expression of laural acid.New rape germplasm resources with Lyso-phosphatidic acid acyltransferase genes will have the good application value.The paper reports that Lyso-phosphatidic acid acyltransferase gene is cloned from coconut endosperm,the plant expression vector by 35S drive is built successfully,and 6 rape plants with Lyso-phosphatidic acid acyltransferase gene are selected from 20 genetic transformation rape plants by agrobacterium-mediated method.
