During the postgenomics era the information about genomic sequence and gene functions provides a new foundation for evolutionary biology and ecology As the first whole-genome sequenced plant Arabidopsis thaliana and its wild relatives have played a critical role in understanding the evolution of genomics and speciation Both A halleri and A lyrata are closely related to the model species A thaliana A halleri ssp gemmifera occurs in northeastern China Japan and Taiwan; while its sister A halleri ssp halleri is mainly distributed in Europe Geographical barriers such as Tienshan Mountain Range isolate these intraspecific sisters Likewise A lyrata ssp kamchatica and ssp lyrata occur in East Asia and North America respectively Such distribution patterns seem to be consistent with allopartic speciation The comparison between ancestral and extant polymorphism by multilocus can be informative about the population genetics of speciation In this study we collected and analyzed DNA sequences of 98 genes from four wild relatives of A thaliana A halleri ssp gemmifera A halleri ssp halleri A lyrata ssp kamchatica and A lyrata ssp lyrata The ancestral states of these four species were compared to each other in terms of level of genetic variation However the ancestral species at the time of speciation were substantially more polymorphic than the extant geographical populations The observations are not fully compatible with speciation by strict allopatry At some species pairs parapatric speciation seems more reasonable in speciation of Arabidopsis The 98 gene sequences are also used for the congruence test between gene genealogy and species phylogeny Only 28 genes support the species phylogeny but there are 23 genes supports another major genealogy { lyrata} thaliana Based on the phylogenetic position change of A lyrata ssp kamchatica and Ks value for each species pair suggested the recent directional gene flow between A halleri ssp gemmifera and A lyrata ssp kamchatica

阿拉伯芥是第一个完成基因体定序的开花植物,其基因体资讯提供植物学研究的重要依据;在解析阿拉伯芥属物种的亲缘关系以及种化机制等重要的演化议题时,阿拉伯芥近缘的野生物种自然成了不可或缺的关键;跟阿拉伯芥近缘的物种包括A halleri及A lyrata,其中A halleri ssp gemmifera主要分布於中国东北、日本以及台湾,与近缘的A halleri ssp halleri其分布於欧洲隔著天山及大陆的障蔽,而A lyrata ssp kamchatica主要分布於东北亚及台湾,与分布於北美五大湖的A lyrata ssp lyrata被北极圈所分隔,这样的分布模式暗示异域种化的可能。藉由多基因分析比较祖先物种与现生物种遗传歧异度的相关可提供讯息探讨种化时期的族群遗传结构,本研究针对A halleri ssp gemmifera、A halleri ssp halleri及A lyrata ssp kamchatica、A lyrata ssp lyrata四个物种,两对互为亚种的姊妹群,以阿拉伯芥为外群进行研究,在四个物种完成98个同源基因的分子序列,利用套装软体MCMCcoal来估算祖先物种的遗传变异,亦估算现生物种的核苷酸歧异度,观察到?多物种配对中祖先物种遗传多型性大於现生物种DNA歧异度,显示异域种化模型并无法完全解释阿拉伯芥属物种的种化模式,在某些物种配对间邻域种化模式应比异域种化更为可能;在基因树与物种树的比较,98个基因片段的亲缘模式只有28个是与已知物种树一致的,有23个基因其树状图支持{ lyrata} thaliana的型式,藉由kamchatica位置的变化以及估算各物种配对间的平均同义置换率,推测在A halleri ssp gemmifera与A lyrata ssp kamchatica间具有近代的单方向基因交流。

Recently, Shelnutt and co-workers obtained discrete porphyrin nanosheets reprecipitated from their solutions;[3] Sathish and co-workers constructed hexagonal C60 nanosheets using a liquid–liquid interfacial precipitation method;[4] the groups of Yao[5] and Hu[6] prepared singlecrystalline nanosheets of polycyclic aromatics using a surfactant- assisted reprecipitation and a physical vapor transporting method, respectively; and Zhang and co-workers suggested that molecules with intramolecular charge-transfer dipole moments could be grown into quasi-2D nanostructures.

近年来,Shelnutt及其同事由他们的溶液再沉淀获得了离散的卟啉纳米片[3]; Sathish和他的同事用液-液界面沉淀法构建了六边形的C60纳米片[4]; Yao[5]和Hu[6]分别用表面活性剂辅助的再沉淀和物理气相输运法制备了多环芳烃的单晶纳米片;而Zhang和他的同事提出,具有分子内电荷转移偶极矩的分子可以生长成准二维的纳米结构[7]。

The son of a father to whom history will accord certain attenuating circumstances, but also as worthy of esteem as that father had been of blame; possessing all private virtues and many public virtues; careful of his health, of his fortune, of his person, of his affairs, knowing the value of a minute and not always the value of a year; sober, serene, peaceable, patient; a good man and a good prince; sleeping with his wife, and having in his palace lackeys charged with the duty of showing the conjugal bed to the bourgeois, an ostentation of the regular sleeping-apartment which had become useful after the former illegitimate displays of the elder branch; knowing all the languages of Europe, and, what is more rare, all the languages of all interests, and speaking them; an admirable representative of the "middle class," but outstripping it, and in every way GRE ater than it; possessing excellent sense, while appreciating the blood from which he had sprung, counting most of all on his intrinsic worth, and, on the question of his race, very particular, declaring himself Orleans and not Bourbon; thoroughly the first Prince of the Blood Royal while he was still only a Serene Highness, but a frank bourgeois from the day he became king; diffuse in public, concise in private; reputed, but not proved to be a miser; at bottom, one of those economists who are readily prodigal at their own fancy or duty; lettered, but not very sensitive to letters; a gentleman, but not a chevalier; simple, calm, and strong; adored by his family and his household; a fascinating talker, an undeceived statesman, inwardly cold, dominated by immediate interest, always governing at the shortest range, incapable of rancor and of gratitude, making use without mercy of superiority on mediocrity, clever in getting parliamentary majorities to put in the wrong those mysterious unanimities which mutter dully under thrones; unreserved, sometimes imprudent in his lack of reserve, but with marvellous address in that imprudence; fertile in expedients, in countenances, in masks; making France fear Europe and Europe France!

他的父亲在历史上固然只能得到一个低微的地位,但他本人是值得敬重的,正如他父亲值得受谴责。他有全部私德和好几种公德。他关心自己的健康、自己的前程、自己的安全、自己的事业。他认识一分钟的价值,却不一定认识一年的价值。节俭,宁静,温良,能干,好好先生和好好亲王。和妻子同宿,在他的王宫里有仆从负责引导绅商们去参观他们夫妇的卧榻(在当年嫡系专爱夸耀淫风以后,这种展示严肃家规的作法是有好处的)。他能懂并且能说欧洲的任何种语言,尤其难得的是能懂能说代表各种利益的语言。他是&中等阶级&的可钦佩的代言人,但又超出了它,并且,从所有各方面看,都比它更伟大。他尽管尊重自己的血统,但又聪敏过人,特别重视自身的真实价值,尤其是在宗枝问题上,他宣称自己属于奥尔良系,不属于波旁系;当他还只是个至宁极静亲王殿下的时候,他俨然以直系亲王自居,一旦成了国王陛下,却又是个诚实的平民。在大众面前,不拘形迹,与友朋相处,平易近人;有吝啬的名声,但未经证实;其实,他原不难为自己的豪兴或职责而从事挥霍,但他能勤俭持家。有文学修养,但不大关心文采;为人倜傥而不风流,朴素安详而又坚强。受到家人和族人的爱戴,谈吐娓娓动听,是一个知过能改、内心冷淡、服从目前利益、事必躬亲、不知报怨也不知报德、善于无情地利用庸材来削弱雄才,利用议会中的多数来挫败那些在王权下面隐隐责难的一致意见。爱说真心话,真心话有时说得不谨慎,不谨慎处又有非凡的高明处。善于随机应变,富于面部表情,长于装模作样。
