Molecular analysis of anthocyanin-related genes in ornamental cabbage
Bibliographic record
Abstract
Ornamental cabbage (Brassica oleracea var. acephala) is a winter-grown and important decorative plant of the family Brassicaceae, which displays an exceptional coloration in the central leaves of the rosette. Anthocyanins are the key determinant of the red, purple, and blue colors of vegetative and reproductive parts of many plant species including ornamental cabbage. Total anthocyanin content was measured spectrophotometrically, and the highest anthocyanin content was detected in the red followed by light-red and white ornamental cabbage lines. Anthocyanin biosynthesis is controlled by members of three different transcription factor (TF) families, such as MYB, basic helix-loop-helix (bHLH), and WD40 repeats (WDR), which function as a MBW complex. We identified three MYB, six bHLH, and one WDR TFs that regulate anthocyanin biosynthesis in ornamental cabbage. The expression of the regulatory and biosynthetic genes for anthocyanin synthesis was determined by qPCR. The tested structural genes of the anthocyanin pathway were shown to be up-regulated in the red followed by light-red ornamental cabbage lines; however, the expression levels of the late biosynthetic genes were barely detected in the white ornamental cabbage lines. Among the regulatory genes, BoPAP2 (MYB), BoTT8, BoEGL3.1, and BoMYC1.2 (bHLH), and BoTTG1 (WDR) were identified as candidates for the regulation of anthocyanin biosynthesis. This work could be useful for the breeding of novel colorful ornamental cabbage cultivars.

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.
