Classification
Members of the Pseudonocardia genus are classified as such:
Domain Bacteria
Phylum Actinomycetota
Class Actinomycetia
Order Pseudonocardiales
Family Pseudonocardiaceae
Genus Pseudonocardia
Species
This page covers details about the general genus of Pseudonocardia sp. There are currently 53 members of the Pseudonocardia genus.
Description and Significance
Describe the appearance, habitat, etc. of the organism, and why you think it is important. Pseudonocardia are Gram-positive bacteria, meaning they have only one cell membrane and a very thick peptidoglycan cell wall.
Genome Structure
Pseudonocardia sp. have one circular chromosome about six million base-pairs (~6,135 kbp, ~6.1 mbp) in length. Pseudonocardia sp. also often have two extrachromosomal plasmids, named pFRP1-1 and pFRP1-2. Both of these plasmids are circular as well. Both are significantly smaller than the genome; pFRP1-1 is about 297 kbp in length while pFRP1-2 is about half of that size, at 121 kbp in length. All in all, the genetic material housed by Pseudonocardia sp. cells code for 5,109 proteins and 63 RNAs. However, because these bacteria live in the soil, they are difficult to isolate and thus there are only about 20 genome sequences currently available for the entire genus, which houses 53 species.
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
