Abstract

Two mitochondrial DNA fragments, nad4(3c-4r) and nad5(1-2r), were sequenced in 58 larch accessions from the range of Larix olgensis A. Henry. Combinations of the nad4 polymorphic sites formed four haplotypes, two of which (H3 and H4) were unique and two (H1, H2) were common. Haplotype H1 was found only in pure L. olgensis from the vicinity of Olga Bay and in a number of accessions from the southern part of the range. Haplotype H2 was detected in the other samples from the range of Olga Bay larch, as well as in hybrid forms. Similarly to the nad4(3c-4r) fragment, the mtDNA fragment UBC460 was able to differentiate larch populations from the range of L. olgensis examined.

摘要

对来自长白落叶松（Larix olgensis A. Henry）分布范围内的58份落叶松材料的两个线粒体DNA片段，即nad4(3c - 4r)和nad5(1 - 2r)进行了测序。nad4多态性位点的组合形成了四种单倍型，其中两种（H3和H4）是独特的，两种（H1、H2）是常见的。单倍型H1仅在来自奥尔加湾附近的纯长白落叶松以及分布范围南部的一些材料中发现。单倍型H2在来自奥尔加湾落叶松分布范围的其他样本以及杂交形式中被检测到。与nad4(3c - 4r)片段类似，mtDNA片段UBC460能够区分所研究的长白落叶松分布范围内的落叶松种群。
