The study of Mitochondrial DNA Gene Rearrangement in 4 species of birds(Aves: Falconiformes) [PDF]

open access: yes, 2016
线粒体控制区由于进化速率快,被作为分子标记广泛应用于种群遗传学和保护生物学等领域的研究。但最近在许多鸟类的线粒体中都发现控制区存在重复拷贝,并且2个控制区拷贝之间的碱基相似度较高。因此在扩增其中一个控制区基因时可能受到另一个控制区的干扰,而对研究结果产生影响。本研究主要针对隼形目鸟类线粒体DNA(mtDNA)基因组中控制区重复及由此产生的基因重排现象进行研究,初步探讨控制区重复和基因重排产生的过程和机制。 本次实验首次对鹰科中的白头鹞(Circusaeruginosus)、日本松雀鹰 ...
