Asymmetric over-introgression of the indica alleles on chromosome 7 and many specific regions on other chromosomes in the japonica genetic background is consistent with the general trend observed in the RIL and F_2 populations of the same cross, suggesting a high genetic load in the japonica gene pool, and japonica genome experienced a very severe bottleneck by artificial domestication.2 Genetic background effect on QTL expression of grain weight and its related traitsGenetic background effect on main-effect QTL and digenic epistatic QTL mapping for GWT and its related traits including GL, GW and GT was dissected by a large set of reciprocal introgression lines and recombinant inbred lines derived from Lemont and Teqing in Beijing environment.
籼粳相互导入具有不对称性,粳稻向籼稻背景的平均导入频率与期望值相仿,相反籼稻向粳稻背景的平均导入频率大大高于理论预期,位于第7染色体和一些其它染色体的特殊区段存在籼稻等位基因的超导入现象,在来自相同亲本的重组自交系和F_2群体中也观察到同样的导入趋势,表明粳稻基因组具有较大的遗传负荷,粳稻品种在人工驯化过程中曾经历过一个非常剧烈的遗传瓶颈。2水稻籽粒相关性状的主效和互作QTL表达的遗传背景效应利用Lemont和特青培育的双向导入系和重组自交系群体,在北京环境下定位影响千粒重及其相关性状如粒长、粒宽和粒厚的主效和互作QTL,分别在特青背景导入系、Lemont背景导入系和重组自交系下检测到影响千粒重及其相关性状的主效QTL分别为33个、27个和13个,互作QTL分别为4个、8个和23个,其中仅有6个主效QTL(QGwt5,QGl1,QGl3b,QGl4,QGw7和QGw8)在籼粳两个不同背景下共同表达,3个主效QTL(QGwt5,QGwt7a和QGt5)在导入系和重组自交系中共同表达,分别占检测到影响这些性状QTL总数的11.1%和4.3%,未检测到在3个背景下相同表达的互作QTL。

Hence, the result of election in 2008 got unbalance between governability and proportionality. This article tends to measure the degree of disproportionality by Loosemore-Hanby index from 1992 to 2008 and tries to explain how disproportionality occurred from five dimensions-district magnitude, levels of seat allocation, threshold, number of total seats, and ballot structure.
本文的研究目的即是重拾对比例性的视野,透过Loosemore-Hanby D指数测量选制改革前后的比例性偏差程度,检视1992至2008年间比例性偏差数值的变化,并从五个面向-选区规模、席次分配、法定门槛、席次总数、选票结构-解释比例性偏差发生的原因,发现所有的选制设计皆不利於比例性,导致新选制的比例性偏差与旧制度产生极大的落差。

Generally, most of the follicles undergo atresia during their development in mammals, and only a few grow to maturation and ovulation. For many years, the mechanisms of follicular atresia have been one of the foci of study. Recently, with the development in studies on cell apoptosis, it has been proved that follicular atresia is a process of cell apoptosis. However, the endocrinological and molecular evens underlying follicular development and atresia and granulosa cell apoptosis in the goat has not been studied.

The restoration of dentition meant not only to fill the missing teeth and increase the efficiency of mastication, but also to maintain the integrity of dentition and the health of residual teeth, especially loosen teeth that could be reserved. Bone resorption might lead to teeth mobility and the change of occlusal pattern and proximal relationship. Also, the endurant threshold to bite force decreased. Occlusal loads within the normal range to loosen teeth would lead to broken down of periodontal tissues.

Thermoanaerobacter tengcongensis is a rod-shaped, Gram-negative, anaerobic eubacterium that was isolated from a fresh water hot spring in Tengchong, China. Using a"whole-genome-shotgun"method, we sequenced its 2, 689, 445-bp genome from an isolate, MB4〓(Genbank Accession Number AE008691). The genome encodes 2, 588 predicted coding sequences . Among them, 1, 764 (68. 2%) are classified according to homology to other documented proteins, and the rest, 824 CDS (31. 8%), are functionally unknown. One of the interesting features of the T. tengcongensis genome is that 86. 7% of its genes are encoded on the leading strand of DNA replication.
