Abstract

fetched live from OpenAlex

A large circular plasmid detected in Francisella novicida-like strain PA10-7858, designated pFNPA10, was sequenced completely and analyzed. This 41,013-bp plasmid showed no homology to any of the previously sequenced Francisella plasmids and was 8-10 times larger in size than them. A total of 57 ORFs were identified within pFNPA10 and at least 9 of them encoded putative proteins with homology to different conjugal transfer proteins. The presence of iteron-like direct repeats and an ORF encoding a putative replication protein within pFNPA10 suggested that it replicated by the theta mode. Phylogenetic analyses indicated that pFNPA10 had no near neighbors in the databases and that it may have originated within an environmental Francisella lineage. Based on its features, pFNPA10 appears to be a novel extra-chromosomal genetic element within the genus Francisella. The suitability of pFNPA10 as a vector for transformation of species of Francisella by conjugation remains to be explored.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
