查询词典 diapause

With primers designed according to sequence(AY052417) of diapause pupae of oriental tobacco budworm registered on GenBank, a double-strand cDNA fragment of DH gene was obtained from RT-PCR amplification and was further cloned into pGEM-T Easy vector.

根据GenBank发表序列(AY052417)设计引物，以烟夜蛾(Helicoverpa assulta Guenée)滞育蛹为材料，利用RT-PCR技术扩增到滞育激素(diapause hormone，DH)cDNA，并通过TA克隆的方法将其克隆至pGEM-T Easy载体上，对目的基因进行测序，并利用设计的酶切位点将目的基因从T载体上切下。

Higher temperature (24℃) inhibited diapause,and diapause did not occur at 27℃.

相同短光照下，低温促进滞育，在15℃、18℃和21℃下滞育率分别为100%、93.1%和66.7%；高温(24℃)抑制滞育，滞育率仅为13.3%；温度为27℃时不滞育。

The experiments of diapause induction showed that both short daylength and low temperature were major factors of diapause induction in T.

诱导滞育实验表明：短日照和低温是诱导二斑叶螨发生滞育的主要因子。

However, there were 41.2% individuals entering diapause at LL; 83.7% individuals developed without diapause at DD.

然而在全光条件下，有41.2％的个体滞育；在全暗条件下则有83.7％的个体发育。

When the eggs entered diapause at a temperature,it was not remarkable to terminate diapause with the same temperature.

当卵在某一孵育温度下进入滞育时，继续以相同温度对滞育进行解除，效果不明显，显示出滞育卵对高温反应的多样性。

SG removal, or diapause hormone shortage, decreased triglyceride and fatty acid content in ovary significantly, while the content of diglyceride and free fatty acids in the fat body and diglyceride in the blood increased, indicating that diapause hormone may promote the transportation of the triglyceride in the fat body into the ovary during silkworm egg formation.

咽下神经节摘除时卵巢中的甘油三脂和脂肪酸的含量都显著降低，而脂肪体中的甘油二脂、游离脂肪酸和血液中的甘油二脂含量增加，说明滞育激素在蚕卵形成过程中有促进脂肪体甘油三脂向卵巢转送的作用。

The experiment results showed that at the beginning of diapause, some inhibition existed in the metabolism of converting glycogen to sorbitol and glycerol in the artificially synthesized hormone induced diapause eggs and it led to increment of trehalose, sorbitol and glycerol in the eggs and advancement of diapause termination in them. As a result, some eggs could not complete fetation and died before hatching.

试验结果表明，合成滞育激素诱导形成的滞育卵在滞育初期糖原向山梨醇和甘油的代谢反应中存在某种障碍，使卵内海藻糖、山梨醇和甘油含量减少，蚕卵滞育不深，滞育提前解除，以致胚胎发育中能量供应不足，部分卵不能完成胚胎发育而在孵化前死亡。

Compared with natural diapaused eggs, the time of diapause termination in induced diapause eggs was advanced by about 30 days, most of the unhatched eggs being bluish dead eggs.

与自然滞育卵相比，诱导滞育卵的解除滞育时间提前30天左右，未孵化卵中大部分为转青死卵。

The diapause rate induced under differenteshort-light decreases with increasing temperature at＞20℃,and decreases underdifferent long-daylengths with increasing temperature distinctly at＞22℃;For SDT, the diapause rate is 69.23%～90.91% at 28℃.But its photoperiodic responses curve isanomalous wavilness at 30℃,showing the photoperiodic responses didn\'t occured.

温度在大猿叶甲的滞育诱导中起决定性作用：无论光周期如何，当温度≤18℃时，龙南种群成虫均进入滞育；修水种群在温度≤20℃时，成虫均进入滞育；山东泰安种群在温度＜25℃时，全部个体进入滞育；哈尔滨种群在温度≤28℃时，全部个体进入滞育。

The diapause hormone -pheromone biosynthesis activating neuropeptide gene encodes five neuropeptides, DH, PBAN,α-SGNP,β-SGNP, and γ-SGNP (suboesophageal ganglion neuropeptide), all of which share the C-terminal pentapeptide FXPRLamide sequence and the pentapeptide fragment has been shown to be the active core required for their activity.

以鳞翅目的昆虫为研究对象，对滞育激素(diapause hormone，DH)-信息素生物合成激活肽(pheromone biosynthesis activating neuropeptide，PBAN)基因的表达定位、表达变化及其功能进行了研究。
