| 1. | In plants , the expression of many genes is regulated at transcriptional level , and mostly by cis - and trans - acting elements
许多植物基因表达的调控发生在转录水平上，主要受顺式元件和反式因子的调控。 |
| 2. | Upregulation of neurod mrna expression might underlie elf - emf effect on promoting mesencephalic progenitors to a neuronal phenotype
Emfs的促神经前体细胞神经元向分化的效应与其在转录水平上调neurodmrna的效应有关。 |
| 3. | This paper sumerised reserach development of plant invertase isoforms , characteristic , function and its gene expression regulatory
综述了近年来植物转化酶的种类、特性、功能及其基因表达在转录水平和翻译水平调控机制的研究进展。 |
| 4. | The mechanisms of gene silencing include copy numbers and configuration of transgene , integration sites in plant and transcription of transgene , etc
基因沉默的机制是多方面的，包括转基因的拷贝数和构型、在植物上的整合位点、转基因的转录水平等。 |
| 5. | Gene silencing , a common phenomenon in phb production through nuclear transformation , had n ' t been observed in the chloroplast transgenic plants analyzed by northern dot blot
Northern点杂交检测表明与phb合成相关的三个基因均能在转录水平表达，未出现核转化中经常发生的“基因沉默”现象。 |
| 6. | However , embryos conceived from brg1 - depleted eggs exhibited a zga phenotype including two - cell arrest and reduced transcription for approximately 30 % of expressed genes
然而，由brg1蛋白缺失的卵细胞受精后形成的胚胎表现出zga表型变化，包括两细胞期的发育停止以及近30 %表达基因的转录水平降低了。 |
| 7. | Homology - dependent gene silencing ( hdgs ) , which is the generic term for transcriptional gene silencing ( tgs ) , post - transcriptional gene silencing ( ptgs ) and rnamediated virus - resistance ( rmvr ) have been shown to frequently occur in transgenic plants
其中，同源依赖的基因沉默又可以分为转录水平的基因沉默和转录后水平的基因沉默。 |
| 8. | Previously , we haved identified that ssmapkk was induced in stems by salt stress . then the ssvp orf was integrated into the plant expression vector pcambia1300 and ssmapkk orf was integrated into the plant expression vector prokii
以前的实验已证明ssmapkk的转录水平受盐胁迫的诱导，由此推测ssvp和ssmapkk都与盐地碱蓬对盐的反应有关。 |
| 9. | A full - length enolase cdna of 1734bp from d . salina ( genebank accession no . 245549 ) was acquired by 5 " race and 3 " race . the sequence of enolase gene from d . salina ( dseno gene ) was analyzed by using bioinformadcs
选择盐藻23srna作为内标基因，利用半定量rl ，一pcr对经不同渗透震动后( o一48小时)烯醇酶基因转录水平的表达量进行了测定。 |
| 10. | It was indicated that regulation of 20ahsd activity was not due to post - translational modification by either phosphorylation cycle or glycosylation , but rather at the transcription level of 20ahsd gene expression in previous research papers
以往研究表明20 hsd活性的调节不是通过糖基化、磷酸化或去磷酸化等翻译后修饰实现的，而是以转录水平的调节为主。 |
