Haloxylon ammodendron (C. A. Mey.) Bunge is a host for the holoparasitic plant Cistanche deserticola Y. C. Ma, the original source of medicinal material known as Herba Cistanchis. The inter-simple sequence repeat marker was used to assess the genetic variations and relationships among six accessions of H. ammodendron with a total of 120 individuals collected from three localities in the Alxa Desert, inner Mongolia, China. At each locality, individuals both parasitized (PP) by C. deserticola and non-parasitized (NP) were sampled. The results showed that Nei’s gene diversity and Shannon’s index of PP accessions were higher, but were not significantly different, from those of NP accessions. An unweighted pair-group method arithmetic average dendrogram showed two clusters, one that included all PP accessions, and the other the NP accessions. Genetic differentiation therefore existed between PP and NP accessions, which might be attributed to low gene flow between the NP and PP groups (Nmionship between genetic distance and geographic distance within each group, although not statistically significant in this study, might be associated with high gene flow in both the NP and PP groups.

目的从分子水平证实空间搭载对梭梭种子后代的遗传物质发生变异。方法利用"神舟"四号飞船搭载的梭梭种子地面种植,进行简单重复间序列(inter-simple sequence repeats,iSSR)检测。结果空间搭载的梭梭和地面对照经iSSR分析,94个iSSR引物中,80个引物扩增的DNA带型一致,14个引物扩增的DNA带型表现多态性。空间搭载的梭梭和地面对照相比,共发现5个特异位点,分别为uBC834-1000,uBC834-1200,uBC840-3000,uBC841-2000和uBC846-1100。另外,地面对照组的多态位点比率(P)、Nei基因多样度(h)和Shannon多样性指数(i)均低于空间搭载组。结论空间环境可引起梭梭遗传物质DNA水平上的变异。
