Interpretive Summary:

Technical Abstract: The Order Pseudonocardiales is made of up a single family Pseudonocardiaceae which forms a distinct cluster between the Frankineae and Streptomycineae when members of the taxa are subjected to 16S rRNA gene phylogenetic analysis. The family contains 26 genera including Pseudonocardia, Actinoalloteichus, Actinokineospora, Actinomycetospora, Actinophytocola, Actinosynnema, Alloactinosynnema, Allokutzneria, Amycolatopsis, Crossiella, Goodfellowiella, Haloechinothrix, Kibdelosporangium, Kutzneria, Labedaea, Lechevalieria, Lentzea, Prauserella, Saccharomonospora, Saccharopolyspora, Saccharothrix, Sciscionella, Streptoalloteichus, Thermocrispum, Umezawaea, and Yuhushiella. These genera contain strains which are heterogenous in their morphological and chemotaxonomic features but, in general, they are predominantly mycelial actinobacteria with 8 genera having sporangia, pseudosporangia, and synnemata, and motile spores as a feature of at least two genera genus. There are no common chemotaxonomic features though the majority contain galactose in their cell walls and phophatidylethanolamine and the menaquinone MK9 (H4), though the latter is absent in the type species of the family. There are 8 monotypic genera and another 8 that contain between 2-5 species, with three genera Amycolatopsis (60), Pseudonocardia (47), and Saccharopolyspora (22) containing half the 237 species of the family. For ease of differentiating the taxa the majority of the morphological, chemotaxonomic, and physiological traits are presented in comprehensive tables.
