基因组分析是描述新分类群的主要依据之一。然而，要获得所有具有有效命名法的放线菌的基因组序列，还需要十年的测序工作。本文描述了放线菌门的成员的较高的分类等级的重排，使用16S rRNA基因序列的同源性和可用的基因组序列的同源性的支持。根据16SrRNA基因序列的精确聚类分析，我们将放线菌门425个属的所有已知有效命名的放线菌划分为6个纲、46个目、79个科，其中包括16个新目和10个新科。1940年颁布的《微球菌名录》（Micrococcales Preparation 1940）（1980年批准名录）修订。Nouioui et al. 2018现在分为11个单系目：修订的Micrococcales和10个提议的新目Aquipurifiales，Beebergiales，Bogoriellales，Brevibacteriales，Cellulomonadales，Demequinales，Dermabacterales，Dermatophilales，Microbacteriales和Ruaniales。此外，Stackebrandt等人1997修订了“放线菌”类别。Nouioui et al. 2018在没有任何命名类型的情况下进行了描述，因此“放线菌”的名称被认为是非法的。根据《国际原核生物命名规则》第8条，帕克等人，2019年，我们提出了放线菌纲这一名称，该名称是通过使用放线菌目布坎南1917（1980年批准列表）的词干修订而形成的。Zhi et al. 2009，以取代名称“放线菌”。建议的新纲放线菌的命名类型是Actinomycetales Buchanan 1917（Approved Lists 1980）修订。Zhi等人，2009年。
Genome analysis is one of the main criteria for description of new taxa. Availability of genome sequences for all the actinobacteria with a valid nomenclature will, however, require another decade's works of sequencing. This paper describes the rearrangement of the higher taxonomic ranks of the members of the phylum 'Actinobacteria', using the phylogeny of 16S rRNA gene sequences and supported by the phylogeny of the available genome sequences. Based on the refined phylogeny of the 16S rRNA gene sequences, we could arrange all the members of the 425 genera of the phylum 'Actinobacteria' with validly published names currently in use into six classes, 46 orders and 79 families, including 16 new orders and 10 new families. The order Micrococcales Prevot 1940 (Approved Lists 1980) emend. Nouioui et al. 2018 is now split into 11 monophyletic orders: the emended order Micrococcales and ten proposed new orders Aquipuribacterales, Beutenbergiales, Bogoriellales, Brevibacteriales, Cellulomonadales, Demequinales, Dermabacterales, Dermatophilales, Microbacteriales and Ruaniales. Further, the class 'Actinobacteria' Stackebrandt et al. 1997 emend. Nouioui et al. 2018 was described without any nomenclature type, and therefore the name 'Actinobacteria' is deemed illegitimate. In accordance to Rule 8 of the International Code of Nomenclature of Prokaryotes, Parker et al. 2019, we proposed the name Actinomycetia which is formed by using the stem of the name Actinomycetales Buchanan 1917 (Approved Lists 1980) emend. Zhi et al. 2009, to replace the name 'Actinobacteria'. The nomenclature type of the proposed new class Actinomycetia is the order Actinomycetales Buchanan 1917 (Approved Lists 1980) emend. Zhi et al. 2009.
