Using the intact G1-nuclei prepared from an isogenic yeast strain lacking mitochondrial DNA , we demonstrated that the DNA synthesis observed within the first 10-20 min was largely due to mitochondrial DNA synthesis, whereas nuclear DNA synthesis did not begin until after a 10-20 min lag period.

利用从缺少线粒体DNA的菌株中制备的完整G1期细胞核，证明了最初10-20min的滞后期内的DNA合成主要是由线粒体DNA合成造成的，而核DNA合成是在经过10-20 min后才开始。

To understand the CMS mechanism caused by unedited form of atp9 deeper,atp9 gene was cloned from three sterile tobacco lines and their isogenic fertile lines.

植物雄性不育最常见的是细胞质雄性不育，它在雌花两性花异株种类的进化中起到积极作用(Budar等，2001)。

To determine differential expression of genes between near isogenic lineMardler/7*Bainong 3217 and Bainong 3217,cDNA-AFLP was employed to assay gene expressed in different time points after inoculation with powder and different treatments.

采用cDNA-AFLP(cDNA-amplified fragment length polymorphism)技术，对小麦抗白粉病近等基因系Mardler/7*百农3217和百农3217材料的不同处理，于接菌后不同时间点的基因表达进行了表达分析。

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.

S型细胞质雄性不育系的一对近等基因系S-Mo17Rf3Rf3 和S-Mo17rf3rf3为材料，采用TdT介导的dUTP DNA末端标记、细胞色素C免疫原位杂交和DNA寡聚核小体片段电泳等方法，分别在细胞学水平和DNA水平上研究了玉米CMS-S小孢子败育的细胞程序性死亡过程。

In order to determine the genetic differences between high molecular weigh glutenin subunits 17+18 and 7+8, HMW-GS 17+18 was introduced into Longmai 20 by 6 consecutive backcrosses with biochemical marker assisted selection. The near isogenic lines of HMW-GS 17+18 and 7+8 were obtained and grown in the experimental field of Crop Breeding Institute of Heilongjiang Academy of Agricultural Sciences in 2006. The field experiments were designed using the method of two line-contrast arrangement with four replicates.

为了解小麦Glu-B1位点HMW-GS 17+18与7+8的遗传差异，利用生化标记和连续6次选择性回交的方法将17+18亚基转移到黑龙江省小麦品种龙麦20中，获得了龙麦20的Glu-B1位点HMW-GS17+18与7+8的近等基因系。2006年将NILs种植在黑龙江省农业科学院育种研究所的试验田，田间设计采用双列对比排列，4次重复。

A cross was made between Zhenshan 97 and Zhenshan 97, a near isogenic line that derived its Wx allele from Minghui 63 by sucessive backcrossing.

将携带明恢63Wx等位基因的近等基因系珍汕97与珍汕97杂交，得到F2大群体。

Four resistance genes, Xa4, xa5, xa13 and Xa21 in the near-isogenic line IRBB60 from IRRI were pyramided into breeding lines in South China using PCR-based marker-assisted selection.

本研究以携带Xa4、xa5、xa13、Xa21 4个抗白叶枯病基因的IRBB60与8个水稻新品系，组配8个杂交组合。

Based on the traits and the molecular markers of Sorghum×Sudan grass, the near-isogenic lines (N1Ls) of plant height, leaf number and related molecular markers were determined from the recombinant inbred line F(subscript 6:7) family. The material could be used for the QTLs analysis.

以株高等表型性状和分子标记为基础，从高粱×苏丹草的F(下标 6：7)重组自交系群体中分离株高、叶片数2个性状及对这2个性状有效应的分子标记的近等基因系，为精确定位性状的QTL及分析QTL的作用提供有用的遗传材料。
