摘要
以3个转基因棉和各自的常规棉亲本为试材,研究转基因棉与常规棉间棉株体内营养物质和次生物质含量的差异性。结果显示:供试的3个转基因棉棉株体内缩合单宁、葡萄糖、蔗糖、麦芽糖含量以及可溶性糖总量均低于各自的常规棉亲本;单宁酸、棉酚、果糖、海藻糖、鼠李糖和各种氨基酸含量以及游离氨基酸总量也与各自的常规棉亲本有差异,表明外源基因的导入影响了棉株体内上述物质的合成与代谢。同时,本研究首次在棉株体内发现了单宁酸的存在。
Three transgenic cotton cultivars and their own conventional parents were used as test materials to study the differences in the contents of nutrients and secondary substances in cotton plants between the transgenic and conventional cottons. The results showed the contents of condensed tannin, glucose, sucrose, maltose, and all the soluble sugars in the transgenic cottons were lower than those of their own conventional parents, and there were some differences in the concentration of tannic acid, gossypol, each amino acid, fructose, mamnose and trehalose all the free amino acids between the transgenic and non-transgenic cotton cultivars, which indicated non-organic gene inserted in the transgenic cotton had some influences on the changes in nutrients and secondary substances. Furthermore, the tannic acid was found in cotton leaves for the first time.
