Elements present in mineral nutrient reserves in dry <i>Arabidopsis thaliana</i> seeds of wild type and <i>pho</i>1, <i>pho</i>2, and <i>man</i>1 mutants
Bibliographic record
Abstract
Comparison of wild type and mutants of Arabidopsis thaliana offers an opportunity to study the genetic control of nutrient storage in seeds. We used energy dispersive X-ray analysis to determine the elements present and their relative amounts in globoids of dry wild-type seeds, as well as seeds of a reduced total P uptake mutant (pho1), a phosphate accumulator (pho2), and a metal accumulator (man1). Globoids are spherical inclusions, rich in phytate that function as a store for inositol, P, K, Mg, Ca, Fe, and Zn. Key findings of this study were the following: (i) globoids in protein bodies from nine different tissues and (or) organs in dry Arabidopsis thaliana seeds contained P, K, Mg, and Ca, and sometimes traces of Fe and Zn; (ii) globoids contained higher Ca and lower Mg amounts than occur in globoids in seeds of most other plant species; (iii) globoids in comparable tissue and (or) organ regions of seeds were very similar in elemental composition for wild type and all mutant plants.Key words: Arabidopsis, dry seeds, phytate, mineral nutrient mutants, phosphorus, globoids.

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.
