摘要: |
梵净山冷杉和元宝山冷杉是极度濒危的国家一级重点保护植物。应用叶绿体微卫星标记(cpSSR)研究它们的遗传多样性,并与同属的广布种岷江冷杉的一个种群进行比较。结果表明:3对cpSSR引物(Pt63718、Pt30204和Pt71936)在这3种冷杉的249个个体中共检测到21个等位基因,组成35种单倍型; 它们的单倍型数和有效单倍型数分别为梵净山冷杉(No=12,Ne=3.92),元宝山冷杉(No=9,Ne=3.28),两者均低于广布种岷江冷杉(No=14,Ne=11.57); 梵净山冷杉和元宝山冷杉的稀有单倍型较少,其频率最高的单倍型分别出现在该种群的46.0%和44.1%的个体中; 梵净山冷杉(He=0.75)和元宝山冷杉(He=0.70)的单倍型多样性也低于岷江冷杉(He=0.97)。梵净山冷杉和元宝山冷杉的叶绿体微卫星遗传多样性水平低。 |

Abstract: |
Abies fanjingshanensis and A. yuanbaoshanensis are critically endangered plants. We used chloroplast microsatellite marker to compare the genetic diversity of A. yuanbaoshanensis and A. fanjingshanensis with a widely distributed species A. fargesii var. faxoniana. A total of 21 alleles and 35 haplotypes was detected in 249 individuals from 3 pairs of primer(Pt63718,Pt30204 and Pt71936). The number of haplotypes(No),effective number of haplotypes(Ne)of A. fanjingshanensis(No=12,Ne=3.92)and A. yuanbaoshanensis(No=9,Ne=3.28)were lower than A. fargesii var. faxoniana. A. fanjingshanensis and A. yuanbaoshanensis had less rare haplotypes. The haplotype diversity(He)of A. fanjingshanensis(He=0.75)and A. yuanbaoshanensis(He=0.70)were also lower than A. fargesii var. faxoniana(He=0.97). A. fanjingshanensis and A. yuanbaoshanensis had a relatively low level of genetic diversity at chloroplast microsatellite. |
