麦黄酮广泛存在于单子叶植物中，最近已证明，麦黄酮及其甙是水稻转基因表达的主要诱导因子［１］，这一发现显示了麦黄酮在转基因研究和利用生物工程技术培育水稻新品种方面有重要价值．然而，麦黄酮在自然界中存在较微量，难于满足深入研究的需要，也限制了它在培育水稻... Wheat flavonoids are widespread in monocotyledons and it has recently been shown that the flavonoids and their glycosides are the major inducer of rice transgene expression [1]. This finding shows that the use of tricin flavonoids in transgenic research and the use of bioengineering techniques to breed new rice cultivars There is an important value. However, there is a small amount of wheat flavonoids in nature, it is difficult to meet the needs of further research, but also limits its cultivation of rice ...
