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.

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.
