用210个10碱基随机引物对玉米多胞质雄性不育系Mo17-CMS-19A(T组)、Mo17-CMS-Shang26(S组)、Mo17-CMS-C(C组)和它们的保持系Mo17以及对新选育的尚未知其不育类型的糯玉米不育系Tai-A和它的保持系C103等6个品系的线粒体基因组进行了系统的RAPD分析。试验结果如下:(1)对其中40个引物的扩增产物进行了聚类分析,绘制出6个品系的树式遗传关系图,并计算出了它们之间的遗传距离。其中,Tai-A和5个品系间关系较远,遗传距离为24.9;Mo17-CMS-19A和Mo17-CMS-C间关系最近,其遗传距离为6。(2)用OPAC-02、OPAN-05、OPG-19、OPT-09和OPT-12等5种引物的扩增产物制作了6个品系的RAPD指纹,其中OPAC-02680、OPAC-021053、OPAN-05680、OPAN-05370、OPT-121230、OPT-09800和OPG-19290结合起来可以分别作为鉴别Mo17-CMS-Shang26、Mo17-CMS-C、Mo17-CMS-19A、Tai-A、Mo17、C103的分子标记,为快速、方便检测6个品系提供了可靠的?
A total of 210 10-mer random primers were used to analyze the effects of Mo17-CMS-19A (group T), Mo17-CMS-Shang26 (group S), Mo17- CMS-C Line Mo17 and mitochondrial genomes of 6 lines of newly mated waxy maize CMS line Tai-A and its maintainer line C103, which have not yet been well-known for their sterile types, were systematically analyzed by RAPD. The experimental results are as follows: (1) The amplification products of 40 primers were clustered and the tree genetic relationships of the six lines were drawn, and the genetic distance between them was calculated. Among them, Tai-A was distantly related to 5 lines and the genetic distance was 24.9. The relationship between Mo17-CMS-19A and Mo17-CMS-C was the closest, with a genetic distance of 6. (2) RAPD fingerprinting of six lines was made with the amplification products of OPAC-02, OPAN-05, OPG-19, OPT-09 and OPT-12. OPAC-02680, OPAC-021053, OPAN -05680, OPAN-05370, OPT-121230, OPT-09800, and OPG-19290, respectively, can be used as primers to identify Mo17- CMS-Shang26, Mo17- CMS- C, Mo17- CMS- 19A, Tai-A, Mo17, C103 Molecular markers provide reliable, fast and easy detection of 6 strains?
