In order to clone AVR-Pia, the flanking sequence of MS220K4 was used as a probe to screening the TAC library and 17 positive clones were obtained. Further restriction enzyme mapping and Southern blot analysis on 10 of the 17 positives clones narrowed the avirulence gene to a region of 10 kb.

为克隆AVR-Pia基因，以MS220K4的侧端序列为探针筛选稻瘟菌基因组TAC文库，得到17个阳性克隆，通过对其中10个进行的限制性内切酶分析并结合Southern杂交确定了目的基因所在区域。

The results showed that the microbial community could degrade 39.6% of rice straw gross weight within five days. When the culture medium volume was 1/5 of the whole and pH at 6 on the 5 days culture, the CMC reached the highest of 14 IUml^(-1). During the rice straw degradation, more than ten kinds of products were detected using GCMS. DGGE detected the dynamic change of microbial community composition, and the microbial composition changed greatly in different periods. The phylogenetic tree derived from 16s rDNA sequence was found that the closest relatives belong to Clostridium sp., Brevibacillus sp., Bartonella sp.、Bacteroidetes sp.

目的：寻求一种治疗睫毛缺损的简单有效的手术方法。方法：在耳后或枕后发际内切取一条带毛发的完整头皮。利用特殊器械将毛干及毛囊完整分离，用植毛针把带完整毛囊的毛发移植于睫毛缺损处。

A cDNA for endo-β-1,4-glucanase was isolated by RT-PCR, and rapid amplification of cDNA ends reaction from taro leaves (Colocasia esculenta var. esculenta).

本研究利用RT-PCR及rapid amplification of cDNA ends的方法，自槟榔心芋叶片选殖内切型纤维素分解酵素cDNA。

The RT-PCR product was inserted into pTG19-T vector and transformed into E. coli successfully. By blastn, the sequence results of Kunming mus musculus were in complete accordance with the conservative sequence of Genbank NR_003278 (791bp-1153bp). By Blastn in NCBI, the sequence with little difference among animals was confirmed to be conservative. After Blastn, fourteen complete CDS coding for different animals were chosen. According to VECTOR NIT 9.0 software, the similarities between Kunming mus musculus and bos taurus, homo sapiens, erinaceus europaeus, cricetulus griseus, sus scrofa, dasypus novemcinctus, rattus norvegicus, rabbit, equus caballus, macaca fascicularis, didelphis virginiana, monodelphis domestica and vombatus ursinus was 67%, 100%, 100%, 36%, 100%, 100%, 67%, 100%, 100%, 92%, 99%, 99% and 99%. In the phylogenetic tress constructed with the forteen 18S rRNA by Treeview, the Kunming mus musculus clustered with cricetulus griseus, sus scrofa and rabbit, which was nearer to cricetulus griseus and was most far away from macaca fascicularis.(3) After sencodary structure analyses of 18S rRNA of mus musculus, an oligonucleotide fragment for RNAi was designed and synthesized, which was transformed into plasmid, and restriction enzyme analyses and sequencing results should the expression plasmid pGPH1/ GFP/Neo-mouse-sh 18S rRNA were constructed for RNAi successfully.

结果①通过RT-PCR检测显示18S rRNA基因在小鼠卵巢组织和单个GV期、MⅠ期卵母细胞中均有表达，且在未成熟卵母细胞中，MⅠ期的表达明显强于GV期的表达；②RT-PCR产物克隆测序结果显示：昆明小鼠18S rRNA基因保守区序列与基因库序列[NR_003278保守区部分(791bp～1153bp)]完全一致；Blastn比对结果发现：在不同物种中差异较小，选出14种生物18S rRNA全序列经VECTOR NIT 9.0软件分析，提示昆明小鼠18SrRNA与牛、人类、刺猬、中国仓鼠、猪、犰狳、褐鼠、兔子、马、食蟹猴、负鼠、短尾猊、袋熊的18S rRNA的相似率依次为67%，100%，100%，36%，100%，100%，67%，100%，100%，92%，99%，99%，99%；Clustal 1.81和Treeview构建出的分子进化树表明：在上述14种生物中昆明小鼠与中国仓鼠进化关系最近，与兔子、猪聚成一簇，与食蟹猴进化关系最远；③根据18S rRNA二级结构设计并合成RNA干扰寡核苷酸片段，重组质粒经过限制性内切酶及测序表明成功构建了pGPH1/GFP/Neo-mouse-sh 18S rRNA干扰表达质粒。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
