Love was the maternal donor of the polyploid Elymus; the "Y" genome existed in the StY-genome Elymus may be differentiated from the St genome, i.e., the autopolyploid StSt-genome species probably experienced genomic differentiation within a species after autopolyploidy, leading to the significant genomic change and resulting the StY-genome allotetraploids; the StY genome species distributed in the Central Asia with a high level of genetic diversity radiated to the Western and Eastern Asia, under the environmental selection and other factors, and only a few species spread to the western Asia and most species have remained in the Central and eastern Asia.
3分子证据表明在StY基因组的物种之间有明显的地理分化,中亚可能是StY基因组披碱草属植物的分化中心,并在此基础上,StY基因组的披碱草属植物向东亚和西亚进行了快速的辐射,形成了现代StY基因组物种的分布格局;多次杂交、迁移和分化是StY基因组的披碱草属植物进化的主要动力。(4)拟鹅观草属物种可能是所有披碱草属植物的母本供体。

The least paedomorphic behavior pattern may be that of the basenji , bred in Africa to hunt alongside humans almost on a peer basis; this breed is often described as highly independent, neither needing nor appreciating a great deal of human attention or nurturing, often described as "catlike" in its behavior.
证明狗是从狼快速进化的一个例证是狗是性早熟或幼态持续的。跟大多物种一样,如小狼比起成年狼更偏向群居和比较少的具有支配力;因此,当进行优选时,不管是有意或无意的,最终的结果看来似乎是把这种幼体的特性带入了成年种群中,而非产生一个复杂的独立新行为。对包括人类自身的许多驯养动物皆是如此,人类很多特征与幼倭黑猩猩类似。这种幼态持续选择的结构自然是导致了幼体生理特征的保留。

And their most important achievement, in Mr Dickey's estimation, is to have turned New York's multicultural diversity to their advantage, building up a team of more than 600 linguists fluent in some 50 languages and dialects. In 2007 NYPD analysts published a 90-page booklet,"Radicalization in the West", seeking to pass on what they had learnt about the home-grown threat in Europe and America.
Dickey认为,他们最大的成就,就是将纽约的多元化特性成功融入到他们的队伍中,建立了一支由600多名精通50多种语言和方言的专家所组成的队伍。2007年纽约警署出版了一本名为"西方世界的激进化"的90页的小册子,来揭示他们所了解到的日益增加的欧美本土威胁。

To improve the yield and quality of wheat is an important project to breeder with genetic method. Wild emmer (Triticum. Dicoccoides Kom), as a close species to common wheat, has many good characteristics which can be used to improve common wheat (. T. aestivum L) and is precious material in wheat evalution.
野生二粒小麦(Triticum.dicoccoides Kom)作为与普通小麦(T.aestivum L)亲缘关系较近的一个种,具有许多优良的特性,在小麦的遗传改良中占据着重要的位置,同时,野生二粒小麦是也是研究普通小麦遗传进化的珍贵材料本研究运用SSR分子标记方法对野生二粒小麦与普通小麦的A、B染色体组的同源性进行研究;同时,为了探讨野生二粒小麦的耐盐性能否应用在普通小麦的遗传改良中,采用水培法对从以色列引进的93份野生二粒小麦的耐盐性进行了初步探讨,为普通小麦的遗传改良提供实验依据。

The evolutionary relationships were investgated by comparing the results from molecular data alone or molecular data combined morphological characters using different analysis methods: maximum parsimony by PAUP(superscript *) 4.0 and Bayesian inference by MrBayes 3.0B4. Base composition and ti/tv of 28S rDNA D2 regions were analyzed by PAUP(superscript *) 4.0. The results showed that GC content of the 28S rDNA D2 gene sequences of subfamily Euphorinae ranges from 40.00% to 49.25%. Transversion frequency of sequence variable sites among species of Euphorinae was higher than that of transition. The subfamily Euphorinae was proved to be a paraphyletic group with close relationship to subfamilies Neoneurinae and Cenocoelinae; only two tribes, Meterorini and Microctonini, were proved to be monophyletic groups; Centistini, Cosmophorini, Euphorini and Dinocampini were paraphyletic groups; the basal position of tribe Meterorini within Euphorinae was partially supported by our phylogenetic trees, and tribe Microctonini was proved to be a group at the top of the trees.
结果表明:优茧蜂亚科的28S rDNA D2基因序列片段的GC%含量在40.00%~49.25%之间变动,而对于碱基替代情况来讲,优茧蜂亚科各个成员间序列变异位点上颠换大于转换;不同的分析和算法所产生的系统发育树都表明目前根据形态定义出的优茧蜂亚科Euphorinae不是一个单系群,而是一个与蚁茧蜂亚科Neoneurinae和高腹茧蜂亚科Cenocoelinae混杂在一起的并系群;在优茧蜂亚科内部,悬茧蜂族Meterorini和食甲茧蜂族Microctonini(排除猎户茧蜂属Orionis)为单系群,而宽鞘茧蜂族Centistini、大颚茧蜂族Cosmophorini、优茧蜂族Euphorini、瓢虫茧蜂族Dinocampini为并系群;悬茧蜂族Meterorini在优茧蜂亚科Euphorinae内位于基部位置的观点得到部分的支持,同时食甲茧蜂族Microctonini被判定为相对进化的类群。

Are virtually the same as in 2006, except for his strikeout/inning rate.
王建民现在是洋基的王牌投手---这是当他由台湾过来时很少被想像到的事情,2007年球季最终他有19胜-7败的成绩,相较於2006年的19胜-6败,当年他获得赛扬奖票选第2名,除了他的三振率之外,2007年王小民其他的数据(自责分率、每局被上垒率、被全垒打数等等)实际上是和2006年相同的,他的三振率大幅提高50﹪----这个提升是这位27岁投手持续成长进化的好兆头。

Mainly belonged to Loranthaceae. Plants of Phacellaria Benth. and their hosts were mainly distributed in tropical and subtropical area. Plants of Phacellaria Benth. maybe originated in tropical area in the south of China before Tertiary. Their ancestors were parasitic on ancestors of some plants of Loranthaceae by chance during Tertiary. It took them millions of years to form a sturdy relationship between parasites and hosts. Ph. rigidula was a hemi-parasitic subshrub. In area observed, its host was mainly Taxillus caloreas var. fargesii.
的硬序重寄生(Ph.rigidula)及其寄主植物做为研究植物与植物间协同进化的材料,对重寄生属植物的起源、与其寄主的分布、硬序重寄生的形态学特性、解剖学以及化学成分进行了研究,结果表明:重寄生属植物主要寄生在桑寄生科植物上,分布区与其寄主的基本一致,均主要分布在东南亚和中国南部的热带与亚热带地区;重寄生属植物可能起源于第三纪之前某一时期的华南热带地区,随后向周边地区扩散。
