血皮槭叶绿体DNA非编码区差异序列筛选和分析

[目的] 筛选出高变异率的叶绿体DNA序列，以进行血皮槭天然群体的谱系地理学研究。[方法] 以血皮槭16个天然群体为试材，对叶绿体基因组20个非编码区序列进行测序研究，并利用筛选出的高变异率cpDNA序列初步分析了其遗传变异。[结果] 序列比对和系统发育分析结果显示血皮槭cpDNA种内变异非常低，9个cpDNA序列检测到不同程度的变异位点，其中只有4个序列psbJ-petA、ndhF-rpl32、trnD-trnT和trnH-psbA表现出较高的变异水平。[结论] 筛选出的4个高变异率cpDNA序列，可以在分子水平上研究血皮槭种内的系统发育、遗传变异和种群历史动态，为进一步研究濒危种血皮槭的分...

[Objective] By screen highly variable cpDNA sequences to study the phylogeography of Acer griseum. [Method] Twenty non-coding cpDNA sequences were sequenced. The genetic variation of sixteen natural populations in A. griseum was preliminarily analyzed with the selected highly variable sequences. [Result] Sequences alignment and phylogenetic analysis showed that the intraspecific variation of cpDNA in A. griseum was very low. Different variation were detected in some loci of nine cpDNA sequences and a relative high level of variation displayed in four sequences psbJ-petA, ndhF-rpl32, trnD-trnT and trnH-psbA. [Conclusion] The four selected highly variable cpDNA sequences could be used to stud
