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.

The cause of virulence decline of hypovirulent isolate Ep-1PN of Sclerotinia sclerotiorum (Lib.) de Bary has been studied through transmitting test and analysing its offsprings derived from single ascospore. When the colony of a normal strain Ep-1PNA 183 intermingled with the colony of Ep-1PN, its margin became abnormal, just like Ep-1PN. Cultures isolated from top-tip of the colony of Ep-1PNA 183 showed the hypovirulence and its associated properties of Ep-1PN. Moreover, a series of cultures which have characteristics between Ep-1PN and normal strain could be isolated from stipes of Ep-1PN. More than 200 offsprings derived from single ascospore of Ep-1PN were normal strains. According to those results, there exists a transmissible cytoplasmic hypovirulent element in hypovirulent isolate Ep-1PN of S. sclerotiorum.

美国现代意义上的英才教育发端于20世纪20年代。在其百年发展历程中,美国学界围绕三大核心议题展开持续论争:“何谓英才”“谁的教育”以及“如何教育”,分别涉及英才的定义、选拔标准以及英才教育的实践形式。论争背后,“公平”与“卓越”两大价值取向之间的博弈贯穿其中,而美国英才教育也在公平质疑中不断发展。开展英才教育既是实现英才儿童个体潜能最大化发展的重要举措,也是推动社会创新、增进民族福祉的国家战略选择。对于我国而言,应加快建立英才教育体系,助益创新型国家建设和人才强国战略的实施。
