Portal protein diversity and phage ecology
Bibliographic record
Abstract
Recent whole-genome cyanophage sequencing (Sullivan et al., 2010) has revealed that the sequences of some genes do not match those published previously as single-gene sequences derived from DNA fragments PCR-amplified from phage isolates. Specifically, the g20 gene sequences for S-SSM7 (gene GI:189397276, protein GI:189397277) and Syn33 (gene GI:189397306, protein GI:189397307) in Sullivan and colleagues (2008) were incorrect. The revised sequences do not alter g20 tree topology or the conclusions of Sullivan and colleagues (2008). The source of error for these gene sequences is not certain, but could have its origin in either a clerical error, PCR contamination and/or mixed phage stocks. On this latter point, it has recently come to light that triplicate plaque purifications do not always result in pure stocks for these cyanophages, possibly due to the fluid consistency of the agarose plates (0.28% agarose) required for growth of the host. More reliable purification procedures have subsequently been developed. However, as mixed phage stock preparations could influence host range, we recommend that published host range data (Sullivan et al., 2003) be verified before their use in further research.
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.

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; both teacher heads agree on what is shown here.
