| 1 | 基因差异表达分析方法及其在作物遗传育种中的应用显示文摘植物基因的差异表达是细胞形态和功能多样性的根本原因,也是各种生理及病变过程的物质基础.分析基因差异表达是近30年来分子生物学研究的重点,研究方法也从最早的差减杂交、差异显示PCR和cDNA代表性差异分析等,不断地发展到基于测序的表达系列标签和转录组测序技术,其中高通量测序技术的应用,使得分子生物学进入后基因组时代,特别是转录组测序可高效率、大批量地获取差异表达基因.通过基因差异表达分析,可挖掘农作物的优异农艺性状、高品质、抗性以及杂种优势等相关基因,辅助常规育种,提高农作物的品质、产量、抗性等综合性状,并为探究其机理、机制奠定基础. | 苏在兴 高闰飞 李强 | 2017 | 江苏师范大学学报(自然科学版)2017，35，1： | 5 |
| 2 | Cloning and Expression Level Analysis of Two BnaANT Candidate Genes in Brassica napus显示文摘AINTEGUMENTA (ANT) gene has been proved to have a novel function on controlling the organ size and the seed weight in Arabidopsis thaliana, the research on its orthologous gene in Brassica napus will be of potential interest to elucidate the molecular mechanism of rapeseed development and increase the rapeseed output. A SMART cDNA library of the flower bud from B. napus cultivar Zhongshuang 9 was constructed, and the full-length cDNAs of two homologous BnaANT candidate genes were cloned by PCR in B. napus, namely BnaX.ANT.a (GenBank accession no. DQ211969) and BnaX.ANT.b (accession no. DQ211970). They shared 87.1 and 83.4% amino acid identity with ANT of A. thaliana, respectively. There is 87.4% amino acid identity between BnaX.ANT.a and BnaX.ANT.b. By quantitative real-time PCR, the obviously differential expression levels of the two BnaANT candidate genes were detected in the 28 DAF seeds of the big and small grains B. napus lines, the expression abundance of BnaANT in the 28 DAF seed of 9311 was over three times compared to that of 9260, which indicates that these two BnaANT genes are also likely related to the floral organ size and the seed weight in B. napus. | CHEN Bo WANG Tai-xia WANG Han-zhong LI Yun-chang YAN Xiao-hong WANG Li-jun WEIWen-hui | 2010 | Agricultural Sciences in China2010，9，4： | 0 |
