Mitogen-activated protein kinase kinase 6 negatively regulates anthocyanin induction in Arabidopsis
Bibliographic record
Abstract
Arabidopsis mitogen-activated protein (MAP) kinase kinase 6 (MKK6) has previously been shown to play important roles in plant immunity and cytokinesis. Here we report that it is also involved in the negative regulation of anthocyanin biosynthesis in Arabidopsis. Elevated anthocyanin levels are observed in mkk6 knock out mutant plants. RNA-sequencing analysis revealed that the expression level of MYB75 (Myb transcription factor 75), which encodes a key positive regulator of anthocyanin biosynthesis, is up-regulated in mkk6 mutant plants, suggesting that increased MYB75 expression contributes to the elevated anthocyanin levels. In addition, suppression of high sucrose-induced anthocyanin production by pathogen associated molecular pattern-triggered immunity is also dependent on MKK6, further supporting that MKK6 is a key negative regulator of anthocyanin biosynthesis in 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.
