ARID (AT-rich interaction domain) protein is a transcription factor family in higher eukaryotes that regulates cell proliferation, development, and differentiation. Specificity of DNA binding ability in this family prefers AT-rich sequences, but some ARID family proteins are not sequence-specific DNA-binding proteins or they do not bind AT-rich sequences. We found two genes that encode ARID in Giardia lamblia genome database, garid1 and garid2. We analyzed the function of garid1 first. AU1-tagged gARID1 was found to localize to nuclei. During encystation, gARID1 mRNA level decreased emphatically, but protein level increased. We also found that gARID1 can bind AT-rich initiator of the cwp1 promoter by EMSA. Mutation analysis revealed gARID1 binding sequence was AGATC and AATAAAATA. We used ChIP to demonstrate that gARID1 can bind cwp1 gene promoter in vivo.
ARID(AT-rich interaction domain)蛋白质家族是真核生物的一种转因子,在许多同种的真核生物有它的同源基因,这个家族的蛋白质通常与调控细胞的生长、发育和分化的作用有关,而这个家族的蛋白质和DNA的结合能,各种ARID蛋白质的专一性尽相同,过大致上偏好於和AT-rich的序结合;我们已经在形鞭毛虫的基因组中找到个含有ARID 的基因,分别是garid1和garid2,我们首先对於garid1做分析;将AU1标记接到gARID1转染形鞭毛虫,用免疫萤光染色可发现gARID1存在於细胞核中。gARID1的讯息RNA在囊体化后会明显下,过其阳性染色和蛋白质表现有明显增加;EMSA实验中也发现gARID1会明显的与cwp1基因启动子之AT-rich initiator结合,经由突变序分析,也显示gARID1的结合序为AGATC和AATAAAATA,随后我们也用ChIP证明gARID1在细胞内也的确会和cwp1基因的启动子结合。

These odd, harmless creatures, the aquatic emblem of NSW, are treated with affection in Catherine Hill Bay and later Jeff tells me of the uproar a few years ago when a groper was shot near the pier by an out-of-town spear-fisherman.

The Monster of Minden'' is a badly-documented late-Jurassic specimen from the Wiehengebirge, Germany. The German edition of National Geographic for November 1999 contains an article in which this animal's ribs are described as 1.5 times as large as those of Allosaurus, and its teeth are claimed to be a foot long including the root.
从明登来的达斯怪兽""明登怪兽是一种后侏罗纪的生物,来自德国的威亨格布裏尔格的化石标本支离破碎。1999年11月份的德文版国家地理杂志刊登了一篇文章,文章中描述了这种生物的肋骨长度是与它类似的侏罗纪恐龙的肋骨的1.5倍,它的牙齿据称有一英尺长。

Polished stone blocks and brooms and leather wings were strewn across the flagstones, vying for space with animal cages—some empty, some not—metal armatures of unknown creatures covered with ragged pelts or mismatched feathers, sheets of seemingly clear crystal stacked haphazardly against the tapestried walls...
擦亮的石块、扫帚、皮制的翅膀散布在石板上,和那些动物笼子争夺地盘。动物笼子有的是空的,有的不是。里面装着不知名的生物的金属爪子,那些生物不是有着粗糙的毛皮,就是有着搭配不当的羽毛。看上去看是无色晶体的薄片,随意地堆放在挂着绣帷的墙边。

This paper is an attempt to reviewbriefly the following fourresearch trends in plant physiology at the turn of century: from research on biological macromolecules to clarification of complex life activities-genomics,construction and function of gene; a key link in achieving integrated life activity-signal transduction; the energy and material basis of life activity metabolism and its control; the interrelationship between plant and environment (both biological and abiological )-biological coevolution and adaptability.
文摘:简要介绍了当今植物生理学研究中值得注意的四个动向,它们是:从研究生物大分子到阐明复杂生命活动——基因组学、基因结构与功能的研究;实现生命整体性的重要环节——信号传递的研究;生命活动的能量和物质基础——代谢及其调节的研究;植物与环境的相互关系——生物的协同进化和适应的研究。

Our rapidly increasing understanding of the human genome and those of other organisms means that we are becoming capable of genetically modifying ourselves by cutting out ,rearranging,and adding various snippes of our own DNA molecules and implanting DNA swquences form other organisms.This secondary evolution will allow us to change the course and speed of primary evolution (based mostly on the glacially slow process of natural selection) of our own species and other species by creating types of genes not currently found in the rest of nature.
我们很快地增加了对人类基因组以及那些其他生物的了解的方法,我们成为有能力从基因方面修改我们自己的基因,藉由删去关掉、重新排列、以及增加各种的片段在我们拥有的DNA分子以及注入一连串的DNA序列从其他生物,而这第二个发展出来的东西将是允许我们藉由创造的类型(创造的类型:不是属於现在处於自然界中的基因)改变初始发展的过程及速度(初始发展:主要是建立在兵期的缓慢的自然淘汰的过程)在於我们拥有的种类以及其他种类。

The extinction or appearance of these Ostracoda always occurred in a short time interval, and can be correlated locally and globally, so they are of importance in bioeventstratigraphy. This article listed six such biological events in Qaidam Basin and discussed their causes. The extinction of Cetacella reflected temperature decrease at global scale and changes of palaeoclimate zones during the latest Jurassic and the earliest Cretaceous; The rapid decline of Cypridea in the earliest Cretaceous may be a result of the strikes of small planets; at the latest middle-Eocene Austrocypris became extinct, and at Oligocene Hemicyprinotus disappeared. These events related to the changes of the geological conditions at that time. The explosion of Cyprideis at the middle-Miocene was because the rise of Qinghai-Xizang Plateau which resulted in the dry climate and development of salt lakes.
这些水生生物的绝灭或发生均很迅速,在区域或全球范围内均可对比,具有生物事件地层学意义:Cetacella属的绝灭可能是侏罗、白垩纪之交全球性的古气候降温和气候带变化在柴达木盆地的反映;早白垩世之后Cypridea的迅速衰退是地外因素灾变的结果;中始新世晚期的Austrocypris的绝灭、渐新世Hemicyprinotus的绝灭都与当时地质条件的改变存在著内在的联系;中中新世Cyprideis的爆发推断是青藏高原隆升,导致气候乾燥、湖水咸化的结果;而晚更新世晚期1。

共生生物的分布常有不同程度的专一性,而幼生时期的选择、著床后的死亡率、幼体或成体时期的选择可能是造成这种现象的机制,此外共生生物的适应会和宿主有密切的关系。

But for most thinkers in mid-eighteenth century, languages as a function of the mind was a problem for philosophical speculation. Although the natural and inherently biological basis of language has been mentioned, it played no role in the heated argument about the origin of language. The quarrel of whether man had invented language by application of his reason or whether it was God's revelation could assume immense proportions without taking into consideration the biological basis of language.
但是,对大部分18世纪中的思想家而言,把语言作为是人类心智的运作是对哲学性的思考带来纷扰,虽然有提到语言是与生俱来的生物基础,但是对於论辩语言起源的问题上仍是徒劳无功,且无论争论语言是人类理性所产生的或是语言是神授的说,都没有把语言是生物的基础的观点列入考量。
