1应用变性梯度凝胶电泳和16SrDNA序列分析对山羊瘤胃细菌多样性的研究显示文摘以取自3头安装有永久性瘤胃瘘管的土种山羊的瘤胃内容物为材料,经过DNA抽提和PCR扩增,扩增产物利用变性梯度凝胶电泳技术(DGGE,一种DNA指纹技术)分析瘤胃细菌在两种日粮条件下的多样性.同时利用基因序列分析技术,分析了16个在DGGE胶上有匹配带的克隆的16S rDNA序列,并与现有的数据库进行了比较.结果表明,饲喂基础日粮时3头山羊瘤胃内容物的DGGE图谱有一定的相似性(43%~55%);饲料中添加大豆黄酮一定程度上影响了瘤胃细菌的组成,DGGE 谱带变化程度分别为 1 号 36% 、2 号 46% 、3 号 30%。基因序列分析表明,DGGE图谱中优势条带的16S rDNA基因序列中有5个基因序列与基因数据库登录的相关序列的相似性大于97%,8个基因序列的相似性在90%~96%,余下的低于90%。相似性大于97%的5个克隆中,只有1个被鉴定为Prevotella sp .,其余 4 个都属于未被鉴定的瘤胃细菌。姚文 朱伟云 韩正康 Antoon D L Akkermans Barbara Williams Seerp Tamminga 2004中国农业科学2004,37,9:53
2Earth observation in service of the 2030 Agenda for Sustainable Development显示文摘This paper reviews the key role that Earth Observations(EO)play in achieving the Sustainable Development Goals(SDGs)as articulated in the 2030 Agenda document and in monitoring,measuring,and reporting on progress towards the associated targets.This paper also highlights how the Group on Earth Observations(GEO)would contribute to ensure the actual use of EO in support of the 2030 Agenda;and how the Global Earth Observations System of Systems meets requirements for efficient investments in science and technology and a good return on investment,which is elaborated in the Addis Ababa Action Agenda on development financing.Through a number of examples,we first discuss how extensive EO use would:provide a substantial contribution to the achievements of the SDGs by enabling informed decision-making and by allowing monitoring of the expected results;improve national statistics for greater accuracy,by ensuring that the data are“spatially-explicit”and directly contribute to calculate the agreed SDG Targets and Indicators support the fostering of synergy between the SDGs and multilateral environmental agreements by addressing cross-cutting themes such as climate and energy;and facilitate countries’approaches for working across different development sectors,which is,according to the special adviser on the 2030 Agenda,a key challenge to achieve the SDGs.We then focus on the role that GEO could play in enabling actual use of EO in support of the 2030 Agenda by directly addressing the Strategic Development Goal 17 on partnerships.Katherine Anderson Barbara Ryan William Sonntag Argyro Kavvada Lawrence Friedl 2017Geo-Spatial Information Science2017,20,2:8
