Genome-wide survey, characterization, and expression analysis of RING finger protein genes in <i>Brassica oleracea</i> and their syntenic comparison to <i>Brassica rapa</i> and <i>Arabidopsis thaliana</i>
Bibliographic record
Abstract
The ubiquitin-mediated post-translational regulatory pathway regulates a broad range of cell functions in all eukaryotes. It requires the involvement of a large number of E3 ligases, of which more than one third belongs to the RING protein family as in Arabidopsis thaliana. In this study, a total of 756 RING domains in 734 predicted proteins were identified in Brassica oleracea. Their encoding genes were characterized by RING domain type, additional domain, and expression pattern, and mapped on the nine chromosomes of B. oleracea. Comparison of these results with B. rapa and A. thaliana revealed some common as well as species-specific features. Our results showed that the differential gene loss following the whole genome triplication has largely contributed to the RING protein gene number variation among these species, although other factors such as tandem duplication, RING domain loss, or modification had also contributed to this variation. Analysis of RNA-seq data showed that these RING protein genes were functionally diversified and involved in all the stages of plant growth and development, and that the triplicated members were also diverged in expression with one member often more dominantly expressed over the two others in the majority of cases. Our study lays the foundation for further functional determination of each RING protein gene among species of the genus Brassica.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
