MOLECULAR CHARACTERIZATION OF POTYVIRUSES INFECTING POTATO AND VEGETABLES IN IRAQ
Bibliographic record
Abstract
The genetic diversity of potyviruses infecting potato and vegetables in Iraq was determined by reverse transcription polymerase chain reaction (RT-PCR) targeting the 3´ terminal part of the genome. RT-PCR products were cloned and sequenced. Sequence analysis confirmed the occurrence of potyviruses, namely Bean yellow mosaic virus (BYMV) in broad bean, Potato virus Y (PVY) in potato and tomato, and Zucchini yellow mosaic virus (ZYMV) in zucchini squash. BYMV sequences showed maximum nucleotide sequence identity (97.2-98.7%) with isolates from Australia and Japan. Most PVY sequences were very closely related (ca. 99% nucleotide sequence identity) to PVYO: N isolates from USA and Canada, whereas other sequences showed nucleotide identities (98.5-98.7%) with PVYNTN isolates from Poland, UK and Syria. ZYMV sequences showed maximum nucleotide identity (97.9%) with an isolate from Israel. The low genetic diversity amongst Iraqi potyviruses, alongside their high sequence identities with potyviruses from other countries, suggests a relatively recent introduction to Iraq through imported planting materials.

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.
