                        北京市園林科學研究院發布國際首例一串紅基因組圖譜
                        發布時間:2018/9/7 17:15:32       訪問次數:228

                               2018年,《Giga science》在線刊登了由北京市園林科學研究院和北京林業大學科研人員合作完成的題目為‘High quality assembly of the reference genome for scarlet sage, Salvia splendens, an economically important ornamental plant’的研究論文,首次公布了一串紅高質量的基因組圖譜繪制工作。這使我國成為世界上首個繪制出一串紅基因組圖譜的國家,這不僅是植物基因組學研究領域的一項重要成果,更會在未來為市屬公園及花壇景觀的營造提供更多花色的一串紅,甚至還可以對串兒紅這種草花品種的花期做到精準調控。

                              一串紅基因組破譯將開啟一串紅育種新時代,逐步實現經驗育種到精準育種的過渡。除了精準調控花期、縮短生長周期、降低成本外,還可以使花色更豐富,抗逆性強,甚至改變葉片,使其肥厚、光亮,有效隔離病原物。同時,為利用精油鼠尾草和一串紅雜交或利用CRISPR-cas9等基因編輯技術,培育多用途一串紅提供重要的理論參考。
