Zygotene is characterized by the active and specific pairing of homologous chromosomes leading to the formation of a haploid number of bivalents.

偶线期时，以同源染色体活跃的、特定的配对为特征，形成了单倍数的二价染色体。

In the second chapter, sequences from the mitochondrial cytochrome b gene were determined for 25 species from the Acrididae and the homologous sequences of 19 species of grasshoppers were downloaded from GenBank. Phylogeny was reconstructed by MP and Bayesian criteria using Yunnanites coriacea and Tagasta marginella as outgroup.

测定了蝗总科25种蝗虫的线粒体Cyt b部分序列，并从GenBank中下载了蝗总科19种昆虫的Cyt b基因同源序列，以瘤锥蝗科的云南蝗Yunnanites coriacea和长额橄蝗 Tagasta marginella作为外群，用MP法和贝叶斯法重建系统发生树。

This finding well supports that the orb-web similarities between Deinopoidea and Araneoidea are more likely the result of convergent rather than homologous evolution.

重建的系统发生树表明：园蛛总科和妖面蛛总科蜘蛛不是姊妹群，从而支持这两个类群的圆网是平行演化而非同源演化的观点。

Armillaria luteo-virens is a ectomycorrhizal fungus symbiotic with some species of Kobresia in Tibet Plateau, China. A strain was recently isolated from fruitbody tissue of the fungus. To determine whether the strain is the pure culture of the fungus, the internal transcribed spacer region and the first intergenic spacer region (IGS-1) of the nuclear ribosomal DNA of fruiting body and the isolated strain were sequenced and compared. Further, the 5.8S/ITS and IGS-1 sequences of the species were BLAST matched with GenBank database on homology and a phylogenetic tree was constructed based on 5.8S/ITS sequence and two phylogenetic trees were constructed separately based on two IGS-1 sequences.

首次从采自青藏高原、与高原牧草嵩草属Kobresia草本植物形成外生菌根的黄绿蜜环菌Armillaria luteo-virens子实体中分离获得一组织分离菌株，运用rDNA-ITS和rDNA-IGS-1测序技术对该组织分离菌株是否为黄绿蜜环菌的纯培养菌种进行分子鉴定，并基于黄绿蜜环菌的5.8S/ITS和IGS-1序列进行核酸序列数据库GenBank同源性检索比对、构建系统发育树。

There were 85%, 85%, 84%, 83% homology with Populua tomentosa, Populus tremula P. tremuloides, Prunus cerasus, Petunia hybrida, respectively.

经过比对分析，该基因编码的氨基酸序列与毛白杨、欧洲山杨×美洲山杨、樱桃和矮牵牛的α-Expansin基因编码的氨基酸同源性分别为85%、85%、84%和83%。

All of the human, rat and mouse CKLF have chemotactic activities on a wide spectrum of leukocytes.

大鼠和小鼠的CKLF同源物，与人CKLF具有类似的剪切形式并且对白细胞有广谱的趋化作用。

When T-SALK lines were grown on iron deficient and 300uM Ferrozine medium, they showed severe chlorotic, which could be rescued by the addition of supplemental iron.

综上所述，小金海棠MxMYB1在拟南芥中的同源基因Atlg70000对植物铁营养的吸收和利用具有一定的调控作用。

This suggests that they are comagmatic. products. formed under different condi-tions, that is, the shallow--seated inclusions came from the chilled border of theupper magmatic chamber while the deep--seated inclusions from the accumula-tive rocks of the lower magmatic chamber.

反映了它们是同源岩浆在不同岩浆作用阶段的产物，即深源包体来自深位岩浆房中的堆积岩碎块，而浅源包体则来自浅位岩浆房的冷凝边碎块。

A candidate gene could be selected because of its'biological association with some disease or being congenerous to a known gene related to the disease.

候选基因的选择可以基于与疾病间的生物学联系或是该基因与疾病某已知相关基因的同源性。

候选基因的选择可以基于与疾病间的生物学联系或是该基因与疾病某已知相关基因的同源性。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
