果蝇

These share the molecular characteristics of pachytene piRNAs but originate from a differentset of clusters that more closely match those of Drosophila and zebrafish in repeat content.

它们都共享着粗线期 piRNA的分子特征，但是起源于那些更接近于果蝇和斑马鱼重复内容的一系列不同的群体。

They are also co-expressed in the mosquito's maxillary palp, the appendage mosquitoes use to sense carbon dioxide, says Jones.

进一步检测疟疾蚊子发现与果蝇的同源基因GPRGR22和GPRGR24，它们也在蚊子感受二氧化碳的触须上共表达。

Tononi and a growing number of other scientists believe that sleep - not just in flies but also in higher-order mammals - may perform such a pressure-releasing role.

托诺尼和越来越多的科学家们认为，睡眠---不仅仅是在果蝇身上，而且在高级哺乳动物身上---也可能起到这种释放压力的作用。

Objective To study the effect of di-n-butyl phthalate on fertility of female Drosophila melanogaster.

Objective To study the effect of di-n-butyl phthalate on the development of Oregon K Drosophila melanogaster.

目的 研究邻苯二甲酸二丁酯(di-n-butyl phthalate， DBP)对子代果蝇生长发育的毒性作用。

Consequently RNA interference was observed is eukaryotic organisms including fungi, Arabidopsis,C. elegans, trypanosomes, hydra, planaria, Drosophila, zabrafish, and mouse.

到目前为止在真菌、拟南芥、线虫、锥虫、水螅、涡虫、果蝇、斑马鱼、小鼠等真核生物中都发现存在这一基因沉默机制。

Interestingly, the phylogenetic analysis of HSP70 revealed that planarian had a closer relationship to vertebrates, but far from to other invertebrates such as D. melanogaster and C. elegans.

有趣的是， HSP70亲缘关系分析表明：涡虫更靠近脊椎动物，而与无脊椎动物果蝇和线虫相距较远。

Results There was a dose-response relationship between concentration of ponceau 4R and mortality rate of drosophila in acute toxicity test.

结果急性毒性试验中，胭脂红浓度与雌雄果蝇的死亡率呈剂量-反应关系。

The SOD activity decreased and MDA concentration increased significantly （P〈 0.05 ） with prolonged exposure and increased concentration of ponceau 4R, that was fitted with a time-dose-response relationship.

随着胭脂红染毒时间的延长和染毒浓度的增加，雌雄果蝇体内SOD活力明显下降、MDA含量明显升高（P〈0.05），呈剂量-反应关系。

Results Same conservative sites and key catalytic sites existed among SjLDH and LDHs from other species. Similarity of SjLDH compared to CsLDH, TvLDH and HsLDH was 75%, 17%, 58%-60% respectively. Phylogenetic analysis demonstrated that the evolution relation between SjLDH and DmLDH was closer than the relation between SjLDH and CeLDH, the relationship between SjLDH and HsLDH-B,-C was closer than HsLDH-A. Three trans-membrane regions were found, the region of 98aa-106aa in three hydrophilia regions located outside of membrane was inferred as the major antigen epitope. This antigen epitope had significant difference with LDHs from protozoon （ Pf ., Tg ., Tv .） and had 1-3 amino acid residue difference with MmLDH, HsLDH-A,-B,-C, and was the same with CsLDH. One of the key catalytic residues and substrate binding loop were located in this region. Tertiary structure demonstrated that 98aa-106aa was on the surface of the protein and formed a substrate binding loop, other two key catalytic sites were at the position near the loop.

结果 SjLDH与其他物种的同源序列含相同的保守位点及催化活性位点，与华支睾吸虫LDH同源性最高为75％，与阴道毛滴虫LDH同源性最低为17%，与人LDH（HsLDH-A，-B，-C）的同源性为58%~60％； SjLDH与果蝇的进化距离较秀丽隐杆线虫为近，3种人LDH中与HsLDH-B、-C的进化距离较HsLDH-A为近；该蛋白具有3个跨膜区域，3个高亲水性区域，主要的线性表位98aa~106aa位于膜外，与原虫LDH相同区域差异显著，而与其他LDH有1~3个氨基酸的差异，关键催化位点之一及底物丙酮酸结合区域位于该区域，蛋白质同源模建分析表明该区域位于蛋白表面形成环状结构，3个关键催化位点位于该区域或在其附近。
