Control of vein patterning by intracellular auxin transport
Bibliographic record
Abstract
The vein networks of plant leaves are among the most spectacular expressions of biological pattern, and the principles controlling their formation have continually inspired artists and scientists. Control of vein patterning by the polar, cell-to-cell transport of the plant signaling molecule auxin--mediated in Arabidopsis primarily by the plasma-membrane-localized PIN1--has long been known. By contrast, the existence of intracellular auxin transport and its contribution to vein patterning are recent discoveries. The endoplasmic-reticulum-localized PIN5, PIN6, and PIN8 of Arabidopsis define an intracellular auxin-transport pathway whose functions in vein patterning overlap with those of PIN1-mediated intercellular auxin transport. The genetic interaction between the components of the intracellular auxin-transport pathway is far from having been resolved. The study of vein patterning provides experimental access to gain such a resolution-a resolution that in turn holds the promise to improve our understanding of one of the most fascinating examples of biological pattern formation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
