Here, we present a review of the studies of evolutionary genetics (phylogenetics, population genetics, and phylogeography) using genetic data as well as genome scale assemblies in Cactaceae (Caryophyllales, Angiosperms), a major lineage of succulent plants with astonishing diversity on the American continent. To this end, we performed a literature survey (1992-2021) to obtain detailed information regarding key aspects of studies investigating cactus evolution. Specifically, we summarize the advances in the following aspects: molecular markers, species delimitation, phylogenetics, hybridization, biogeography, and genome assemblies. In brief, we observed substantial growth in the studies conducted with molecular markers in the past two decades. However, we found biases in taxonomic/geographic sampling and the use of traditional markers and statistical approaches. We discuss some methodological and social challenges for engaging the cactus community in genomic research. We also stressed the importance of integrative approaches, coalescent methods, and international collaboration to advance the understanding of cactus evolution.
在此，我们对利用遗传数据以及仙人掌科（石竹目，被子植物）基因组规模组装进行的进化遗传学研究（系统发育学、群体遗传学和系统地理学）进行综述，仙人掌科是多肉植物的一个主要谱系，在美洲大陆具有惊人的多样性。为此，我们进行了一项文献调查（1992 - 2021年），以获取有关研究仙人掌进化关键方面的详细信息。具体而言，我们总结了以下方面的进展：分子标记、物种界定、系统发育学、杂交、生物地理学和基因组组装。简而言之，我们观察到在过去二十年中使用分子标记进行的研究有显著增长。然而，我们发现分类学/地理采样以及传统标记和统计方法的使用存在偏差。我们讨论了让仙人掌群落参与基因组研究的一些方法学和社会挑战。我们还强调了综合方法、溯祖方法和国际合作对于推进对仙人掌进化理解的重要性。
