In order to evaluate the effect of over-expressed Mn-superoxide dismutase gene on antioxydation in maize, expression vector with Mnsod gene from wheat was constructed for monocotyledonous plant and used to transform calli of elite maize inbred line by microprojectile bombardment.

为研究过量表达的超氧化物歧化酶基因对提高玉米抗氧化损伤的作用，本研究构建了小麦来源Mnsod基因的单子叶植物表达载体，用基因枪法转化用优良玉米自交系诱导的胚性愈伤组织。

BACKGROUND: Several cardiac ion channel genes have been implicated in monogenic traits with a high risk of sudden cardiac death. Mutations or rare variants in these genes have been proposed as potential contributors to more common forms of SCD, but this hypothesis has not been assessed systematically.

背景：数种心肌离子通道基因和高危心源性猝死的单基因特性有关，这些基因的罕见突变被认为是SCD更常见的潜在促进因素，但是这一假说没有被系统的评价过。

And its developmental expression pattern showed that AmphiRab23b was expressed in the differentiating neural plate and alimentary canal, as the same as the expression pattern of the homologous vertebrate genes, which suggested that AmphiRab23b may function in the development of nervous system and alimentary canal.

时空表达的研究结果进一步显示，AmphiRab23b基因在胚胎发育中的神经板和消化道中表达，与其脊椎动物同源基因的表达模式相似，这说明该基因可能对文昌鱼神经系统和消化道的发育有重要作用。

In this study, we successfully localized the gene responsible fornon-syndromic postaxial polydactyly typeA/B to a 2.5Mb region and analyzedgenes and ESTs in the critical region.

本研究成功地将一个新的遗传性轴后多指家系相关基因确定在19号染色体2.5Mb的范围内，并对关键区域内的基因和EST进行了初步分析，为进一步分析该致病基因的突变奠定了基础。

The three parts of this thesis involve gene regulation, gene structural analysis and novel gene cloning, respectively.

本文的三个部分分别涉及基因的表达调控、重要基因PLZF的结构分析，以及造血系统表达的新基因克隆。

The RNA in situ hybridization experiments revealed that MOC1 was initially expressed in a few epidermal or subepidermal cells in the leaf axil prior to the formation of axillary meristem.

另外，我们发现在moc1突变体中由于MOC1基因的功能缺失突变，导致了分生组织特异性的OSH1基因和控制侧枝伸长的OSTB1基因的表达水平降低。

The RNA in situ hybridization experiments revealed that MOC1 was initially expressed in a few epidermal or subepidermal cells in the leaf axil prior to the formation of axillary meristem. The expression of MOC1 was continued during the formation process of axillary meristem. MOC1 was still expressed after axillary meristem has differentiated into tiller buds.

MOC1基因的组织原位杂交实验表明，在腋生分生组织形成之前，MOC1基因就已经在叶腋里的少数表皮或亚表皮细胞里表达，并且MOC1基因的表达伴随着腋生分生组织形态建成的整个过程；在腋生分生组织分化形成分蘖芽以后，MOC1仍然在整个分蘖芽中表达。

The frequency of losing exon 5-8 was the highest . It was consistent with the results of the FHIT gene whole length cDAN by RT-PCR.Conclusions: The above results showed that the changes of FHIT gene is probably related to the development of kinds of tumors, which is an important molecular event. FHIT gene can be considered to be a tumor suppresser gene, our studys provided a theoretic and experimental data for further research on the function of FHIT gene.

结论本研究结果初步证明FH工T基因改变可能与多种肿瘤的发生有关，是肿瘤发生的一个重要的早期分子事件，支持其作为一个抑癌基因在肿瘤发生中发挥作用，为进一步深入研究FH IT基因的功能提供了理论和实验依据。

Cardiac hypertrophy is one of adaptive responses of the heart to a variety of pathological stimuli, including hypertension, myocardial infarction, congenital heart disease, heart valvula disease, and perturbations in sarcomeric function due to altered expression or mutations of contractile proteins. Increase in wall tension and hormonal stimuli are thought to directly activate various membrane-bound receptors and signal transduction cascade within cardiomyocytes resulting in the activation of immediate early genes and responsive genes such as c-jun, c-fos, c-myc, egr-1, ANF, BNP. Then the expression of construction proteins such as MLC-1, skeletal α-actin was unregulated.

Phylogenetic analysis showed that sugarcane was firstly clustered with maize, then with sorghum and Zoysia japonica, and then with rice.

该基因片段具有其它植物GA20氧化酶基因中存在的保守区；同时，与多种单子叶植物的GA20氧化酶基因的核苷酸和氨基酸序列的同源性在80％和75％以上。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
