Living gymnosperms comprise four major groups: cycads, , conifers, and gnetophytes. Relationships among/within these lineages have not been fully resolved. Next generation sequencing has made available a large number of sequences, including both plastomes and single-copy nuclear genes, for reconstruction of solid phylogenetic trees. Recent advances in gymnosperm phylogenomic studies have updated our knowledge of gymnosperm systematics. Here, we review major advances of gymnosperm phylogeny over the past 10 years and propose an updated classification of extant gymnosperms. This new classification includes three classes (Cycadopsida, Ginkgoopsida, and Pinopsida), five subclasses (Cycadidae, Ginkgoidae, Cupressidae, Pinidae, and Gnetidae), eight orders (Cycadales, Ginkgoales, Araucariales, Cupressales, Pinales, Ephedrales, Gnetales, and Welwitschiales), 13 families, and 86 genera. We also described six new tribes including Acmopyleae Y. Yang, Austrocedreae Y. Yang, Chamaecyparideae Y. Yang, Microcachrydeae Y. Yang, Papuacedreae Y. Yang, and Prumnopityeae Y. Yang, and made 27 new combinations in the genus .
苏铁、银杏、松柏类和买麻藤类。这些谱系之间/内部的关系尚未完全厘清。新一代测序技术已提供了大量序列，包括质体基因组和单拷贝核基因，用于构建可靠的系统发育树。裸子植物系统发育基因组学研究的最新进展更新了我们对裸子植物系统分类学的认识。在此，我们回顾过去10年裸子植物系统发育的主要进展，并提出现存裸子植物的更新分类。这个新分类包括三个纲（苏铁纲、银杏纲和松柏纲）、五个亚纲（苏铁亚纲、银杏亚纲、柏亚纲、松亚纲和买麻藤亚纲）、八个目（苏铁目、银杏目、南洋杉目、柏目、松目、麻黄目、买麻藤目和百岁兰目）、13个科和86个属。我们还描述了六个新族，包括杨氏南洋杉族、杨氏澳洲柏族、杨氏扁柏族、杨氏微卡克族（Microcachrydeae Y. Yang）、杨氏巴布亚柏族和杨氏泪柏族，并在该属中进行了27个新组合。
