Seasonal Changes in Perennial Nodules of Beach Pea (<i>Lathyrus maritimus</i> [L.] Bigel.) with Special Reference to Oleosomes
Bibliographic record
Abstract
Beach pea (Lathyrus maritimus [L.] Bigel.), a potential cold‐climate circumpolar legume crop, grows along the shorelines of Newfoundland, Canada. The nodules undergo winter dormancy and become active in the spring season. The nodules sampled in winter show dormant tissue and bacteria without any loss of structural integrity. In the senescent zone, bacteroids are found to be disintegrated. Oleosomes (lipid bodies) are clearly localized in the meristem, invasion zone, interstitial cells of the symbiotic and senescent zone, vascular tissue, and cortical cells of both winter and summer nodules. In all the tissues, significantly large numbers of oleosomes are seen in histological preparations of nodules sampled in winter compared with nodules sampled in summer. As winter approaches, the nodules show increasing accumulation of lipids. The nodule tissues are protected from winter stress and pathogen attack by suberized peridermal cells. We propose multipurpose functions of oleosomes in root nodules of beach pea, including the release of energy for various metabolic functions in the cells, to prevent freezing in the localized microenvironment of the cells, and to insulate the cells and supply fatty acids for membrane synthesis during cell growth.

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.
