Vacuolar compartmentalisation and efflux of cadmium in barley
Bibliographic record
Abstract
Plants have developed different tolerance strategies to deal with toxic metals. Various factors and mechanisms related to the compartmentalisation of cadmium (Cd) into the vacuoles and the efflux of Cd were investigated to analyse their roles in Cd tolerance in barley. In vacuolar transport assays, the addition of adenosine triphosphate (ATP) alone significantly increased Cd uptake into the vacuole, but more so when both ATP and glutathione (GSH) were supplied together. This suggests that Cd may be partly sequestered as Cd2+ ions via divalent cation transporters, but predominantly as Cd–GSH complexes, most likely via ATP-binding cassette transporter-type transporters. Comparison of the concentrations of 109Cd in whole protoplasts and vacuoles isolated from shoots demonstrated that the majority of the cellular Cd was located in the vacuole. Over 48 h, 12% of the root Cd was effluxed into the external solution when roots were loaded with 109Cd by foliar application. This active excretion may be a detoxification strategy, in addition to the compartmentalisation of the majority of cellular cadmium into vacuoles predominantly as complexed form.

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.
