Sequence analysis showed that the amplified 16S rDNA fragment was closely related to those in the 16Sr Ⅰgroup, with a homology rate of more than 99 %. This fragment had maximum homology, upto 100 %, with those of Ash witches' broom, Epilobium phyllody, and Chinaberry witches' broom phytoplasma strain Jiangxi. Its similarity of 16S rDNA sequence is obviously lower than 97 % as compared with other phytoplasma groups.

结果表明，该片段与16Sr I组中的各植原体同源率均达到99 %以上，其中与16Sr I中的白蜡树丛枝（Ash witches'-broom，AWB，AY566302），柳叶菜变叶（Epilobium phyllody，EP，AY101386）和苦楝丛枝江西株系（Chinaberry witches'-broom，CWB-JX，AY859543）的同源率最高，达到100 %，而与其它组的植原体16S rDNA序列的同源率均低于97 %。

Our experiment is unique to clone porcine IL-4 gene from lymphocytes of the local species of Chenghua porcine and systematically study its expressing effect in vivo on the immune system and immune responses of mouse and pig to trivalent vaccines against Swine fever, the Pasteurellosis and Erysipelas suis and pig paratyphoid vaccine.

将得到的序列在GenBank和EMBL数据库中进行了同源比较，结果表明它与来源于长白猪肠粘膜固有层淋巴细胞的白细胞介素-4有99％同源，与来源于杂交猪T细胞的白介素-4有96％同源，说明猪种及组织细胞来源的不同可能使基因有一定的差异。

The Cyt b gene of Takifugu fasciatus was proved to have good homology with other 13 species of fishes recorded in GenBank and it has 96.1% homology with Takifugu rubripes, about 75% with Mola mola and Masturus lanceolatus. The tRNA gene has 69 nucleotides and the tRNA has 72 nucleotides. Their sequences are the same as those of Takifugu rubripes.

用DNA分析软件对暗纹东方鲀与GenBank中10个目13种鱼类的Cyt b序列进行比较分析，显示暗纹东方鲀与这些鱼类的Cyt b基因具有较高的同源性，与同属红鳍东方鲀的同源性最高，为96.1%；与同目不同科的矛尾翻车鲀和翻车鲀的同源性分别为74.1%和74.8%。tRNA基因由69个碱基组成，tRNA基因由72个碱基组成，与红鳍东方鲀相应tRNA的碱基组成完全相同。

The authors proposed that heterochromatin change in genome might play an important role in balancing the germplasms between maize and its distant relatve after cross and parthenocarpy.

这种变异不仅存在于表型不稳定的早代孤雌系中，而且还存在于表型稳定的高代系中，造成这种变异的原因可能是因为远缘种质的引入影响到遗传平衡进而引起染色体发生结构重排并引起染色质的变化，这种变化与玉米染色体组中非同源染色体间存在的同源片段和因此造成的减数分裂过程中非同源染色体配对有着直接的关系。

Bioinformatics Analysis of Silkworm Development-Related Genes According to sequence homology, homologous genes for 86 genes participating in embryonic development genetic hierarchy of Drosaphila were searched in silkworm genome, including 43 maternal genes, 12 gap genes, 9 pair rule genes, 13 segment polarity genes and 9 homeotic genes. Results show that all but 6 maternal genes have the homologues in silkworm genome and some of them have high similarity.

家蚕发育相关基因的生物信息学分析基于序列的相似性，在家蚕基因组数据中检索参与果蝇胚胎发育调控级联的86个重要基因的同源基因，结果表明，除6个母性基因在家蚕中没有找出同源基因外，其余基因在家蚕中均存在同源基因，并且其中一部分具有相当高的相似性。

The analysis of the identity, the codon usage frequency and the codon usage preference were made to sequences of Carassius auratus auratus serum transferrin cDNA cloned in our laboratory and 14 fish Tf cDNA from reference documentation by DNAman v4.0. The results show that the identity of Tf cDNA sequences among Cypriniformes fishes is more than 46% and the identity of Tf cDNA sequences among Oncorhynchus fishes is between 34%~99% with larger variation.

运用DNAman v4.0分析软件，对克隆的鲫鱼血清转铁蛋白cDNA序列与文献中的14种鱼转铁蛋白cDNA序列的同源性、密码子使用频率和密码子使用偏性进行分析，结果表明：鲤形目鱼类Tf的cDNA序列同源性在46％以上，而鲑形目鱼类Tf的cDNA序列同源性在34%~99％之间，变化较大。

The significant sequence change was found in LTR (including U3 13.2%, R7.5% and U5 5.1%), env (2.7%) and ORE S2 (3.9%) between DLA-EIAV and EAV L,while the predicted amino acid sequence difference of Env and S2 protein from the twostrains were 4.4% and 8.8%, respectively.

EIAV L株与国外已发表的一些相关毒株相比核苷酸序列差异很大，同源性只有79%，RTase的氨基酸同源率只有86%，Gag蛋白的的同源率只有79%，说明EIAV L株与国外已报道的几个EIAV毒株的亲缘关系较远。

The homologies among each TaDREBs genes had greater difference. The homology between TaDREB1 and TaDREB6 reached 87%, while that among other transcription factors were in 44%~53%, which indicated that the role of this type of genes in draught response were different.

结果］各个TaDREBs基因之间的同源性有较大的差异，TaDREB1与TaDREB6的同源性高达87%，其余各转录因子的同源性在44%~53%之间，表明这类基因在干旱应答中所起的作用并不相同。
