Role of <i>Euphalerus ostreoides</i> (Hemiptera: Psylloidea) in manipulating leaflet ontogenesis of <i>Lonchocarpus muehlbergianus</i> (Fabaceae)
Bibliographic record
Abstract
This study deals with the ontogenesis of leaflets and galls induced by Euphalerus ostreoides Crawf. on the second-order veins of leaflets of Lonchocarpus muehlbergianus Hassl. Leaflets had a median submarginal developmental pattern with four layers of ground meristem. Procambial strands were differentiated from the median layers. Simple nonglandular trichomes were differentiated from the protoderm and abscised before leaflet maturation. Mature leaflets had uniseriate epidermis and isolateral mesophyll. Galls were bivalve-shaped, with a single nymphal chamber and glabrous outer epidermis. Sparse trichomes occurred on the margin of the valves and inner epidermis. Cecidogenesis led to vascular neoformation, cell hypertrophy, and conspicuous hyperplasia of the cortical layers, with cytological distinctiveness. Histochemistry of invertases indicated that sugars supplied plant cell machinery. The developmental pattern of nongalled leaf tissues of L. muehlbergianus, as well as the variations caused by the feeding activity of E. ostreoides, were in accordance with a developmental model proposed for Psyllidae galls in the Neotropics. The valves are vascularized leafy appendages that originated from the most adaxial layers of the ground meristem. Vascularization supplied additional feeding sites to E. ostreoides, as well as water uptake, which were of major importance in the determination of the final shape of the gall.

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.
