Histidine kinase activity and the regulation of ethylene signal transduction
Bibliographic record
Abstract
Ethylene is a gaseous hormone that regulates many aspects of plant growth and development. Although the effect of ethylene on plant growth was discovered a century ago, the key players in the ethylene response pathway were only identified over the last 15 years. In Arabidopsis, ethylene is perceived by a family of five receptors (ETR1, ETR2, ERS1, ERS2, and EIN4) that resemble two-component histidine kinases. Of these, only ETR1 and ERS1 contain all the conserved residues required for histidine kinase activity. The ethylene receptors appear to function primarily through CTR1, a serine/threonine kinase that actively suppresses ethylene responses in air (absence of ethylene). Despite recent progress toward understanding ethylene signal transduction, the role of the ethylene-receptor histidine-kinase activity remains unclear. This review considers the significance of histidine kinase activity in ethylene signaling and possible mechanisms by which it may modulate ethylene responses.Key words: ethylene receptor, ETR1, histidine kinase, two-component, phosphorylation, Arabidopsis.

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.
