An Expanded Genetic Toolbox to Accelerate the Creation of <i>Acholeplasma laidlawii</i> Driven by Synthetic Genomes
Bibliographic record
Abstract
We have developed genetic tools for the atypical bacterium Acholeplasma laidlawii . A. laidlawii is a member of the class Mollicutes, which lacks cell walls, has small genomes, and has limited metabolic capabilities, requiring many metabolites from their hosts. Several of these traits have facilitated the development of genome transplantation for some Mollicutes, consequently enabling the generation of synthetic cells. Here, we propose the development of genome transplantation for A. laidlawii . We first investigated a donor–recipient relationship between two strains, PG-8A and PG-8195, through whole-genome sequencing. We then created multihost shuttle plasmids and used them to optimize an electroporation protocol. We also evolved a superior strain for DNA uptake via electroporation. We created a PG-8A donor strain with a Tn5 transposon carrying a tetracycline resistance gene. These tools will enhance Acholeplasma research and accelerate the effort toward creating A. laidlawii strains with synthetic genomes.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
