A significant number of mycoviruses have been identified that are related to plant viruses,but their evolutionary relationships are largely unexplored.A fusarivirus,Rhizoctonia solani fusarivirus 4(RsFV4),was identified in phytopathogenic fungus Rhizoctonia solani(***)strain XY74 co-infected by an ***4 had a genome of 10,833 nt(excluding the poly-A tail),and consisted of four non-overlapping open reading frames(ORFs).ORF1 encodes an 825 aa protein containing a conserved helicase domain(Hel1).ORF3 encodes 1550 aa protein with two conserved domains,namely an RNA-dependent RNA polymerase(RdRp)and another helicase(Hel2).The ORF2 and ORF4 likely encode two hypothetical proteins(520 and 542 aa)with unknown *** phylogenetic analysis based on Hel2 and RdRp suggest that RsFV4 was positioned within the fusarivirus group,but formed an independent branch with three previously reported fusariviruses of ***,the Hel1 and its relatives were phylogenetically closer to helicases of potyviruses and hypoviruses than fusariviruses,suggesting fusarivirus Hel1 formed an evolutionary link between these three virus *** finding provides evidence of the occurrence of a horizontal gene transfer or recombination event between mycoviruses and plant viruses or between *** findings are likely to enhance the understanding of virus evolution and diversity.

A 2-kb Mycovirus Converts a Pathogenic fungus into a Beneficial Endophyte for Brassica Protection and Yield Enhancement

2013年教育技术与管理科学国际会议

作者： Jinbang Zhang yanping fu Department of management science Bozhou Vocational and Technical College

This paper aims at the research into evaluation on innovation ability of innovative city of science and technology. Firstly, it defines the connotation of innovative city of science and technology, and it builds the evaluating indicator of innovation ability of innovative city of science and technology from four aspects, including technical innovation human resources, technical innovation environment, technical innovation input and technical innovation output. Secondly, it builds the model of evaluation on innovation ability of innovative city of science and technology by the factor analysis theory, and puts forward "technology index of city’ innovation ability" to evaluate the ability of innovative city of science and technology. Lastly, we choose seven cites, including. Beijing, Shanghai, Tianjin, Wuhan, Guangzhou, Nanjing, Xi’an, to make an overall evaluation on their innovation ability.

特殊高中是对美国纽约市9所公立选拔性高中的统称。卓越的教育成就使特殊高中声誉斐然,同时又因学生族裔比例失调受到有违教育公平的质疑,其争议的根源在于这些高中将入学考试作为唯一的招生标准。近年来,关于特殊高中入学考试的争议逐渐上升为纽约市政府计划废除这一考试的政策行动,却又因遭到以亚裔为代表群体的反对被暂时叫停。特殊高中入学考试的存废之争,本质上反映了精英主义取向和政治正确取向在教育机会与资源分配中的利益博弈。对于具有"特殊性"的特殊高中而言,质量优先兼顾公平应该成为其坚持的原则和发展方向。

随着对"资优"认识的逐步深入以及资优教育实践的不断开展,美国资优教育发展经历着从资优儿童范式到才能发展范式的转向。然而,两个范式的先识别资优生、再对其进行分类教育的做法,面临着理论、现实以及政策层面的困境。在这样的背景下,适才教育范式得以提出。反应干预教学(Rt I)策略强调为差异化的资优生内部群体提供适合其能力发展的教育,借助反应干预策略,资优教育将走向适才教育。
