The relationship between the dominant<i>Additional</i><i>vein</i>mutant in<i>Drosophila melanogaster</i>and<i>engrailed</i>
Bibliographic record
Abstract
Additional vein (Adv) is a dominant mutation that affects the first wing vein in Drosophila. It also manifests a recessive lethal phenotype and is associated with a large inversion. Using a combination of genetic and cytogenetic techniques, we show that Adv interacts with engrailed (en), likely because one of the inversion breakpoints interferes with en function. Genetic interaction studies reveal that Adv is lethal in trans with various lethal alleles of en and gives an engrailed-like wing phenotype with weak alleles of en. In situ hybridization to polytene chromosomes using en cDNA demonstrates that one of the inversion breakpoints lies within the en coding region. Although the cause of the wing phenotype is not determined herein, it likely is caused by the other inversion breakpoint interfering with a different function. The characterization of this mutation could expedite studies to understand what molecular events result in the Adv phenotype and thereby provide insight into the development of the first wing vein in Drosophila.
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.
