Construction of a genetic map with SRAP markers and localization of the gene responsible for the first-flower-node trait in cucumber (Cucumis sativus L.)

With an F2 population from the cross of two cucumber inbred lines, S06 and S52, sequence-related amplified polymorphism (SRAP) was used to construct a genetic linkage map in cucumber (Cucumis sativus L.). Sixty-four SRAP primer combinations generated 108 polymorphic bands in the F2 population analysis. The average of polymorphic bands produced by one primer pair was 1.5, and the maximum was 5. Using Mapmaker 3.0, a linkage map was constructed, which consisted of 77 SRAP markers distributed in nine linkage groups (LOD≥3.0) and spanned 1114.2 cM with an average interval of 14.5 cM between markers. The gene for the first-flower-node trait, termed ffn, was mapped to linkage group Ⅸ, flanked by DC1EM5 and ME7EM2A at 10.3 cM and 12.1 cM distance, respectively.     

普通高校女生体育课教学规律的探讨

要想上好普通高校女生体育课，必须抓住她们的生理心理特点，并且采取适合她们的教学方法和手段，才能收到较好的效果，高校女生，处于发育旺盛、日趋成熟时期，她们随着年龄的增长，皮下脂肪增厚，体重增加，但身体素质较差，尤其是腰腹肌很差，再加上怕脏怕累，上体育课的兴趣和运动情绪不高。     

主客互动悦和声--从《声无哀乐论》看嵇康的音乐欣赏理论

《声无哀乐论》体现了嵇康独特的音乐欣赏思想。其主要观点有：音乐欣赏的本质在于人获得“和声”的音乐美感；音乐欣赏的过程是欣赏主、客体互动统一的两个心理层次；音乐欣赏的功能在于以“无声之乐”标识自由人格及移风易俗。

A surface-based DNA algorithm for the minimal vertex cover problem

Abstract DNA computing was proposed for solving a class of intractable computational problems, of which the computing timewill grow exponentially with the problem size. Up to now, many achievements have been made to improve its performance and increase itsreliability. It has been shown many times that the surface-based DNA computing technique has very low error rate, but the technique hasnot been widely used in the DNA computing algorithms design. In this paper, a surface-based DNA computing algorithm for minimal ver-tex cover problem, a problem well-known for its exponential difficulty, is introduced. This work provides further evidence for the abilityof surface-based DNA computing in solving NP-complete problems.
