《工程制图》多媒体CAI在微机网络上的实现

《工程制图》多媒体ＣＡＩ课件需要制作大量的三维真彩色动画，由于这种动画的数据量很大，因此，制作工程多媒体ＣＡＩ课件在难度上比一般的多媒体ＣＡＩ大，这类课件的研制在我国仍处在初级阶段，目前这类软件都不能在微机网络上运行，从而影响了工程制图ＣＡＩ在课堂上的使用效果，我们采用Ｖｉｓｕａｌ Ｂａｓｉｃ描述性语言 网上实现了资源共享，解决了实验室中几十个终端学生学习工程制图多媒体课件的问题，这将会降低实验室

Strategy for the mapping of interactive genes using bulked segregant analysis method and Mapmaker/Exp software

A qualitative trait is usually controlled by a single gene, but it may be sometimes controlled by two or even more genes. This phenomenon is called gene interaction. Rapidly searching for linked mo- lecular markers via bulked segregant analysis (BSA) and then constructing regional linkage map with Mapmaker/Exp has become a common approach to mapping single major genes. However, methods and computer programs developed for mapping single major genes cannot be simply applied to interactive genes because the genetic patterns of gene interac- tions are quite different from that of single-gene in- heritance. Up to now, experimental methods for quickly screening molecular markers linked to inter- active genes and statistical methods and corre- sponding computer softwares for simultaneously analyzing the linkage relationships of multiple mo- lecular markers to an interactive gene have not been available. To solve this problem, in this paper, we propose a strategy for mapping interactive genes using BSA and Mapmaker/Exp. We demonstrate that all interactive genes can be mapped by the 'BSA Mapmaker/Exp' strategy using F2 generation (in a few cases, F3 generation is also needed). As BSA and Mapmaker/Exp have been broadly used in gene mapping studies and are well known by many re- searchers, the strategies proposed in this paper will be useful for practical researches.

琉球“沟-弧-盆系”构造地貌: 地质地球物理探测与制图

利用多波束全覆盖水深测量数据和地震、浅地层调查、地质地球物理调查资料及现有研究成果, 对琉球“沟-弧-盆系”构造地貌特征进行了系统的分析研究, 编绘了琉球“沟-弧-盆系”构造地貌图. 指出琉球“沟-弧-盆系”地貌的发育和分布格局主要受构造运动的控制. 琉球岛弧与东海陆架和陆坡构造地貌特征具有明显区别, 前者地质构造上由吐噶喇火山脊、琉球褶皱脊和弧前增生楔及夹于其间的奄美拗陷和弧前拗陷组成, 地貌上表现为岛坡海岭与岛坡断陷盆地相间分布的格局; 东海陆坡是一个新生的被动型陆缘, 地貌上表现为断阶型陡坡, 地形变化连续. 冲绳海槽构造上是一个弧后张裂带, 带内构造活动强烈, 火山活动和热液活动活跃, 已经并正在发生海底扩张. 海槽地貌的发育主要受雁行式排列的海槽扩张轴和东海陆坡断裂带、吐噶喇西缘断裂带的控制. 海槽中央为沿扩张轴发育的中央裂谷盆地和中央火山链, 西~西北侧为自东海陆坡坡麓向海槽中央倾斜的浊流堆积平原, 东~东南侧为自琉球岛弧西坡坡麓向海槽中央倾斜的火山碎屑堆积平原. 冲绳海槽在构造地貌上构成东海陆架和琉球岛弧的天然分隔.

Comparative physical mapping of rice BAC clones linked to resistance genes Glh,Bph-3 and xa-5 in Oryza sativa L. and O. granulata Nees et Arn. ex Watt.

Oryza granulata Nees et Arn. ex Watt. is one of the three wild relatives of rice,which are the most valuable for study and utilization in China.In this study,the homology and physical locations of three rice resistance genes,Glh,Bph-3 and xa-5 are comparatively analyzed between O.sativa and O. granulata by Southern blotting and fluorescence in situ hybridization (FISH).The results of Southern blotting indicate that there exist homologous sequences of the tested RFLP markers in O. granulata.By using three bacterial artificial chromosome (BAC) clones scanned by the tested RFLP as probes, FISH signals are detected on both mitotic and pachytene chromosomes in O.sativa and O.granulata.Dual-color FISH demonstrates that two of the three BAC clones (14E16 and 38J9) are located on the short arm of the same chromosome pair in O. granulata. Additionally, colinearity is shown for the two clones between O.sativa and O.granulata. Another BAC clone 44B4 is located on the end of the short arm of other chromosome pair in these two species.Although the phylogenetic relationship between O.sativa and O.granulata is the most distinct in Oryza and these two species have evidently different biological features and ecological habits, the relative lengths and arm ratios of the detected chromosomes and the relative positions of the tested clone signals on chromosomes in O. granulata are quite similar to those in O. sativa.
