日前,笔者从中国农业新闻网获悉,美国《科学》杂志日前刊载两项新研究成果表明,美国和澳大利亚等国研究人员成功克隆出两种可帮助抵御新型小麦秆锈病变种的基因。该研究成果或为培育新的抗病小麦品种带来希望,并对保障全球粮食安全具有重要意义。为预防和控制Ug99新型小麦秆锈病可能带来的危害, Recently, the author learned from China Agricultural News Network that two new research results published recently by the U.S. “Science” magazine indicate that researchers from the United States and Australia successfully cloned two genes that could help to defend against the new wheat stem rust. The results of this study may bring hope for cultivating new wheat varieties with disease resistance and are of great significance for ensuring global food security. To prevent and control Ug99 new wheat straw rust may harm,
