| 1 | 应用生物技术向小麦导入黄矮病抗性的研究显示文摘小麦黄矮病是我国小麦的主要病害之一,迄今在普通小麦中还未发现抗性材料.经酶联免疫吸附分析,发现在小麦族中有13个种具不同程度抗性.中间偃麦草、小麦-中间偃麦草的八倍体衍生物无芒中4和TAF46及由TAF46育成的小麦附加系L_1均高抗黄矮病.以L_1为抗源,采用CSph突变体和组织培养诱导分别育成了抗病的易位系119880和119899.资料表明其抗性由一个显性基因所控制.筛选出pEleAcc3和pPJN8(E_1-T_1)两个互补DNA分子探针,可探测出在普通小麦遗传背景中的中间偃麦草DNA,在Southern杂交中,中间偃麦草及其衍生物的DNA清晰显示出小麦DNA所缺乏的一条特异带,通过比较其相对深浅程度可判断易位系所获的外源染色体片断的大小,作为黄矮病抗性的选择标志. | 辛志勇 徐惠君 陈孝 林志珊 周广和 钱幼亭 成卓敏 P.J.Larkin P.Banks R.Appels B.Clarke R.I.S.Brettell | 1991 | 中国科学(B辑)1991，，1： | 65 |
| 3 | Progress Toward Implementing the Sendai Framework, the Paris Agreement, and the Sustainable Development Goals: Policy from Aotearoa New Zealand显示文摘In 2015, Aotearoa New Zealand became a signatory to the Sendai Framework for Disaster Risk Reduction 2015–2030(Sendai Framework), the Paris Climate Change Agreement(Paris Agreement), and the Sustainable Development Goals(SDGs). Since 2017 Aotearoa New Zealand has been undergoing governance reform to realign priorities and to improve the management of natural hazards and climate change. The aim of this article is to provide a review of how Aotearoa New Zealand is taking steps to improve consistency of planning across the legislative environment, thereby implementing its commitments to the Sendai Framework, the SDGs, and the Paris Agreement. It provides an overview of the national governance arrangements, with a focus on the key legislative tools;identifies how key terms are defined nationally;and provides an overview of the governance arrangements that contribute to the country’s international obligations. The discussion describes how obligations are applied, and considers two'disruptive and proactive' action examples. Four recommended actions are provided to further implement these international aspirations:(1) take into account these international agreements during the development and implementation of all legislation;(2) build awareness, capability,and capacity within central, regional, and local governments to support implementation;(3) actively evaluate the progress of implementing initiatives designed to reduce vulnerability and strengthen resilience;and(4) ensure that more weight and value are given to indigenous planning documents. | Wendy S.A.Saunders Scott Kelly Suzanne Paisley Larissa B.Clarke | 2020 | International Journal of Disaster Risk Science2020，11，2： | 0 |
