Occurrence of the gametophyte of Agarum clathratum (Laminariales, Phaeophyceae) as an endophyte in Orculifilum denticulatum (Gigartinales, Rhodophyceae)
Bibliographic record
Abstract
SUMMARY An endophytic filamentous brown alga, growing in the red alga Orculifilum denticulatum Lindstrom, was collected from the north-east Pacific, near Juneau, Alaska. Within the host tissue, its branched filaments formed a network in the space between the filaments of the host tissues embedded in the host intercellular substances. Cells of the filaments contained many discoid chloroplasts without pyrenoids. Neither microscopic morphological observation nor culturing was sufficient to reveal the specific identity or even the familial affinity of the alga; in contrast, molecular phylogenetic analysis of its rbcL gene and rDNA ITS sequences showed that it was the gametophyte of Agarum clathratum Dumortier (Laminariales). There are few reports of laminarialean gametophytes in nature; this is the first report actually identifying the species of laminarialean gametophyte in a red alga.
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 machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
