Many studies paid attention to dissect the genetic bases using different emendatory approaches from phenotypic variation to gene discovery, mainly containing QTL mapping, chemical mutagenesis etc. Especially, QTL analysis was executed for a lot of important quantitative traits.

我们可以沿着由表型变异去发现基因之路，更准确地剖析数量性状的遗传基础；尤其是对作物的许多重要的数量性状进行的QTL研究越来越受到重视。

The strongest evidence for linkage in 147 families with late-onset PD was on chromosome 17 near the tau gene -- previously shown to be involved in other neurodegenerative diseases including frontotemporal dementia with parkinsonism and progressive supranuclear palsy.

147个患有迟发型帕金森氏症的家庭在遗传研究中被发现，该病与17号染色体上的tau基因有关联。以前tau基因被认为与其它的神经变性疾病有关，如伴有震颤麻痹的额颞型痴呆以及进行性核上性麻痹有关。

Was used to cons Methods: The pSUPER plasmid cloned into RNA polymeraseⅢ H1 promoter was used to construct new vectors which can code hereditable shRNA aimed to HPV18E6/E7 gene mRNA.

采用克隆有人Ⅲ型RNA聚合酶H1启动子的pSUPER质粒，设计并构建针对HPV18E6、E7基因mRNA的、可稳定遗传的编码发夹状结构的特异性RNA干扰质粒载体。

The phenotypic mean values for the three populations and the midparental heterosis values for the two backcross populations were used for quantitative trait locus mapping and analysis, the genetic basis and correlations betweent the traits were analysed.

将三个群体的表型值和两个回交群体的中亲优势值进行了数量性状位点(quantitative trait locus，QTL)的检测及效应分析，初步分析了持绿性、充实度和产量等农艺性状的遗传基础和各性状间的相关关系。

Photooxidative characteristics and physiological mechanism in leaves of super high yielding hybrid rice Peiai 64S/E32 and its parental lines were investigated by photooxidative treatment mediated with 200 μmol/L of exogenous methyl viologen under a PPFD of 2 000 μmol·m -2 ·s -1 for 1 h.

结果表明相对于含有粳稻成分的母本和高产子代而言，籼稻父本是光氧化敏感型，而子代超高产水稻耐光氧化的特性主要受含粳稻成分的籼稻母本的遗传控制。

Results:The intramembrane proteinic particles of cell membranes of erythrocyte as well as of muscular cells were diminished significantly in DMD.

Duchenne型肌营养不良症是一组由遗传因素所致的的X连锁隐性遗传病，越来越多的学者认为细胞膜的缺陷在本病中有重要地位。

Epigenetic effects,which were defined clearly in recent years,are most often used to denote all those somatically heritable changes in gene expression that do not involve changes in DNA sequence.

后生效应是近几年才定义清楚的一类现象，指所有那些DNA序列没有改变的基因表达后体细胞的遗传表型发生改变的现象。

Objective Machado-Joseph disease/Spinocerebellar ataxia type 3 (SCA3) is an autosomal dominant neurodegenerative disorder caused by an expansion of polyglutamine tract near the C-terminus of the MJD1 gene product, ataxin-3. The precise mechanism of the MJD/SCA3 pathogenesis remains unclear.

目的 马查多-约瑟夫病/脊髓小脑共济失调3型，是由 MJD1基因产物ataxin-3的C-末端的多聚谷氨酰胺发生重复扩展突变而引起的一种常染色体显性遗传的神经退行性疾病，目前它的发病机制还不清楚。
