Previous attempts to introduce transposon Tn4001 into Mycoplasma pulmonis and Mycoplasma arthritidis have not been successful, possibly due to functional failure of the transposon's gentamicin resistance determinant. Tn4001C and Tn4001T were constructed, respectively, by insertion of a chloramphenicol acetyltransferase gene and the tetM tetracycline resistance determinant into Tn4001. Both Tn4001C and Tn4001T transposed in M. pulmonis, and Tn4001T transposed in M. arthritidis. The incorporation of a Tn4001T derivative that contained lacZ into either Mycoplasma species resulted in transformants with readily detectable LacZ activity. Tn4001T may be of general utility for use as a mycoplasma cloning vehicle because tetM functions in all species of Mycoplasma examined thus far.

() is characterized by a reduced genomic size and limited synthetic capacity, including the inability to synthesize nucleotides de novo, relies on nucleases for nutrient acquisition and survival. A number of nucleases have been implicated in pathogenicity, facilitating substrate degradation and contributing to DNA repair mechanisms that enhance bacterial persistence. The present study confirmed that the T5.

Mycoplasma pneumoniae is a small cell wall-lacking bacterium that is a common cause of bronchitis and pneumonia in humans. In addition to its clinical importance, M. pneumoniae has recently been considered a promising model organism for synthetic biology because of its small genome size and unique cell structure.

Linezolid resistance has represented a global concern with its wide dissemination among nosocomial pathogens in recent years. One hundred and two linezolid-resistant (LRSC) were constantly isolated from 2011 to 2021, which demonstrated single clonal dissemination in a Chinese tertiary hospital. A structurally similar -carrying plasmid was identified among 90 isolates.

Mycoplasmas are important model organisms for Systems and Synthetic Biology, and are pathogenic to a wide variety of species. Despite their relevance, many of the tools established for genome editing in other microorganisms are not available for Mycoplasmas. The Tn4001 transposon is the reference tool to work with these bacteria, but the transformation efficiencies (TEs) reported for the different species vary substantially.

Mycoplasma gallisepticum (MG) is an important pathogen that can cause chronic respiratory disease in chickens and infectious sinusitis in turkeys. MG has the ability to form biofilms. The molecular mechanisms underlying MG biofilm formation are complex and poorly understood.
