利用cp rbcL、matK和trnL-trnF基因间隔区对中国属补血草属与白花科其他属的亲缘关系进行了研究。分析表明，白花蛇舌草科是白藜芦科较强的单系姐妹群，通过系统发育分析确定了白花蛇舌草科中的两个类群。利用nrDNA(ITS)和cpDNA(trnL-trnF和PSBA-trnH两个基因间隔区)对中国补血草的遗传多样性进行了初步分析。结果表明，该物种的种群遗传多样性较低，可能与人类活动和繁育系统有关。这些结果已被用来了解中华绒毛虫的进化和种群历史，这是建立该物种有效保护措施的必要条件。(C)2012爱思唯尔B.V.保留所有权利。
Phylogenetic relationship of Limonium and other genera of Plumbaginaceae in China were studied using the cp rbcL, matK and the intergene spacer of trnL-trnF. The analysis showed that Plumbaginaceae was strongly supported monophyletic group sister to Polygonacea, and two tribes were comfirmed by phylogenetic analysis in Plumbaginaceae. Preliminary genetic diversity of Limonium sinense in China was also analyzed in this study by nrDNA (ITS) and cp DNA (two regions of intergenic spacers, trnL-trnF and psbA-trnH). The results showed that the population genetic diversity was low perhaps for human activities and breeding system of this species. These results have been used to understand the evolutionary and demographic history of L. sinense, which is a requisite to establish efficient conservation measures for this species.
