摘要: |
为了研究高产胶量品系的遗传学特征,建立了长心卡帕藻(Kappaphycus alvarezii)物种的ISSR分析方法。用ISSR技术对4株同一来源,形态各异的长心卡帕藻进行了遗传学分析,与11条ISSR引物共扩增得到60条带,其中1条带具有多态性并推测与稳定的经济性状连锁。说明ISSR技术可应用于长心卡帕藻品系筛选,结合其他手段,为分子标记辅助育种提供了可能。 |

The primary application of ISSR analysis on strains identification of Kappaphycus alvarezii |

Abstract: |
To investigate the genetic properties of high Carrangeenans production strains, the method of ISSR analysis of Kappaphycus alvarezii was established. The genetic diversities among 4 strains of K. alvarezii of the same origin which differs in configuration were analyzed. A total of 60 amplification loci were obtained from 11 ISSR primers, of which 1 locus revealed a polymorphism and possible linkage to the economic properties. It was indicated that the feasibility of ISSR could be combined with other measures on K. alvarezii. |
