Identification and mapping of genes for improving yield from Chinese common wild rice (O. rufipogon Griff.) using advanced backcross QTL analysis

To identify useful genes from wild rice which have been lost or weakened in cultivated rice has become more and more important for modern breeding strategy. In this study, a BC4 population derived from 94W1, an acces-sion of common wild rice (Oryza rufipogon Griff.) from Dongxiang in Jiangxi Province of China, as the donor, and a high-yielding Indica cultivar (O. sativa L.), "Guichao 2", as the recipient, was used to identify quantitative trait loci (QTL) associated with yield and its components. Based on the analysis for the genotype of BC4F1 population with 87 SSR markers distributed throughout the genome and investigation of the plant height, yield and yield components of BC4F2, a total of 52 QTLs, were detected. Of 7 QTLs associated with grain yield per plant, 2 QTLs on chro-mosome 2 and chromosome 11 for grain yield, explaining 16% and 11% of the phenotypic variance respectively, were identified. The alleles from Dongxiang common wild rice in those two loci could increase the yield of "Guichao 2" by 25.9% and 23.2% respectively. The QTL on chromosome 2 increasing grain yield of cultivar is actually a major gene, which did not coincide with any previously published QTLs in rice.     

Optical mapping of a rice BAC clone using restriction endonuclease and imaging with fluorescent microscopy at single molecule level

A method of constructing restriction map by optical mapping and single molecule fluorescent microscopy is described. DNA molecules were aligned and adsorbed on a glass coverslip surface by a modified “molecular combing” technique, and then the surface-immobilized DNAs were cleaved in situ with a restriction endonuclease. Individual DNA molecules digested by the endonuclease EcoRⅠ were observable with fluorescent microscopy. Using optical mapping, a physical map of a rice bacterial artificial chromosome clone was constructed. This method will facilitate genomic mapping and tracing the dynamic process in real time at a single molecule level with fluorescence microscopy.

DiffServ网络中服务质量映射函数研究

与集成服务(InteServ)网络模型不同,区别服务(DiffServ)网络模型中的中心路由器是根据几个有限的服务类别而不是会话流的具体情况来转发调度数据包,这就需要一个重要的服务质量映射的过程。依据DiffServ实现方式的不同,服务质量映射的物理框架也有所不同,但一个关键的映射环节总是存在,即依据数据包的相对优先级系数RPI(RelativePriorityIndex)将其映射入相应的服务类别。该文运用数学工具对这一典型环节进行建模,从视频质量入手分析映射函数,最后在一定条件下得到保证视频质量最优的一种映射函数表达式,并从数学证明和实例分析两个方面论证了这种映射函数表达式的最优性。
