Genetic characterization of a red colour morph of <i>Euphorbia esula</i> subsp. <i>esula</i> (Euphorbiaceae) in the floodplains of the Saône (Eastern France)
Bibliographic record
Abstract
A new morph of leafy spurge, Euphorbia esula L., was discovered in the floodplains of the Val de Saône (VDS), France. In this region, this emerging weed shows two different morph colours: the common “green” variant and a rarer “red” variant. We compared the sequence data for the plastid trnT–trnF region among individuals of both morphs from the VDS, as well as other populations from Europe and North America, where this plant is invasive. In addition, we analysed the ploidy found among VDS individuals for both colours. Results showed that both morphs share two of the three chloroplast DNA (cpDNA) haplotypes found in the VDS and are both hexaploids (2n = 6x = 60). These results suggest that the red morph is only an environmental variant of E. esula subsp. esula. Our results indicate that leafy spurge infestations in this region form a genetically diverse structuring composed of three cpDNA haplotypes, two of which are shared by the two morphs.

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.
