【摘要】：隨著轉(zhuǎn)基因技術(shù)的日趨成熟,利用生物工程手段加快改良作物農(nóng)藝性狀,已經(jīng)越來(lái)越顯示出其巨大的應(yīng)用潛力。在改良多基因調(diào)控的復(fù)雜農(nóng)藝性狀方面,單基因轉(zhuǎn)化收效甚微,而長(zhǎng)期以來(lái)多基因轉(zhuǎn)化不僅受限于技術(shù)因素,而且在協(xié)調(diào)表達(dá)調(diào)控、代謝及修飾等一系列相關(guān)基因方面更是難于突破。近期,我國(guó)科學(xué)家首次利用自創(chuàng)的多基因垛疊表達(dá)系統(tǒng),成功在水稻(Oryza sativa)胚乳中合成了具有抗氧化活性的花青素,在復(fù)雜性狀多基因轉(zhuǎn)化領(lǐng)域取得了突破性進(jìn)展。
[Abstract]:With the growing maturity of transgenic technology, the use of bioengineering methods to speed up the agronomic traits of crops has shown great potential for application. In improving the complex agronomic characters regulated by polygenes, the single gene transformation has little effect, and the long-term polygene transformation is not only limited to technical factors, but also in coordination table. It is difficult to break through a series of related genes, such as regulation, metabolism and modification. In the near future, Chinese scientists have successfully synthesized anthocyanins with antioxidant activity in the endosperm of rice (Oryza sativa), and made breakthrough progress in the field of multi gene transformation in the field of complex traits.
