Abstract
Calcium ions (Ca2+) are well known signaling molecules in plant signal transduction pathways including the response to abiotic stress. Particular stimuli cause specific transient elevations in cytosolic Ca2+ ([Ca2+]cyt) with a stimulus-dependent amplitude and temporal pattern. These Ca2+ transients, known as Ca2+ signatures, rely on the counteractive activities of Ca2+-permeable channels and Ca2+-transporting proteins. Whereas the channels causing an increase in [Ca2+]cyt were partly identified, direct evidence for the role of Ca2+-transporting proteins in the determination of Ca2+ signatures was missing. We recently reported on the functional characterization of a stress-responsive PIIB-type Ca2+-ATPase (PCA1) from the moss Physcomitrella patens. This study revealed an essential role of this Ca2+ pump in the adjustment of salt stress tolerance. Most strikingly, the generation of a specific Ca2+ signature in response to salt was abolished in Physcomitrella mutant lines lacking PCA1 activity. Thus, we can provide a direct link for the function of a Ca2+-ATPase in the generation of a specific Ca2+ signature in plants.

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.
