This review describes the development of evolutionary studies of sex based on the volvocine lineage of green algae, which was facilitated by whole-genome analyses of both model and non-model species. Volvocine algae, which include Chlamydomonas and Volvox species, have long been considered a model group for experimental studies investigating the evolution of sex. Thus, whole-genomic information on the sex-determining regions of volvocine algal sex chromosomes has been sought to elucidate the molecular genetic basis of sex evolution. By 2010, whole genomes were published for two model species in this group, Chlamydomonas reinhardtii and Volvox carteri. Recent improvements in sequencing technology, particularly next-generation sequencing, allowed our studies to obtain complete genomes for non-model, but evolutionary important, volvocine algal species. These genomes have provided critical details about sex-determining regions that will contribute to our understanding of the diversity and evolution of sex.
这篇综述描述了基于绿色藻的团藻目谱系的性进化研究的发展，这得益于对模型和非模型物种的全基因组分析。团藻目藻类，包括衣藻和团藻物种，长期以来一直被认为是研究性进化的实验模型群体。因此，人们一直在寻找有关团藻目藻类性染色体性别决定区域的全基因组信息，以阐明性别进化的分子遗传基础。到 2010 年，该组的两个模式物种，衣藻和 Carterioides volvox 的全基因组已经公布。最近测序技术的改进，特别是下一代测序，使我们的研究能够获得非模型但具有进化重要性的团藻目藻类物种的完整基因组。这些基因组提供了有关性别决定区域的关键细节，这将有助于我们理解性的多样性和进化。
