Draft Genome Sequence of <i>Phytophthora abietivora</i> , a Root Rot Pathogen of True Firs in Managed Plantations
Bibliographic record
Abstract
Phytophthora abietivora is a recently described root rot pathogen of true firs ( Abies spp.) and a major contributor to fir plantation decline in eastern North America. We present a 62.17-Mbp draft genome assembly of P. abietivora generated using Oxford Nanopore and Illumina sequencing technologies. The assembly comprises 2,917 scaffolds with an N50 of 43.8 kb, 99.7% completeness, and 15,906 predicted protein-coding genes, including 1,210 secreted proteins. Single-nucleotide polymorphism analysis revealed extended runs of homozygosity and allele frequency shifts, suggesting dynamic extreme aneuploidy. This reference genome will serve as a critical resource for exploring the evolution and pathogenicity of P. abietivora and developing control strategies.

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.
