Genome-wide identification and expression analyses of R2R3-MYB transcription factor genes from two Orchid species
Bibliographic record
Abstract
MYB transcription factors play important roles in different plant biological processes during plant growth, development and stress response. In this study, 101 ( DoMYB1-101 ) and 99 ( PaMYB1-99 ) R2R3-MYB genes were identified in the genomes of Dendrobium officinale and Phalaenopsis aphrodite , respectively. To classify the isolated candidate genes, the R2R3-MYB genes from A. thaliana were selected as references. As a result, all identified DoMYB and PaMYB genes were classified into 22 subfamilies. Phylogenetic analysis revealed that S21 had the largest number of members of all the subfamilies. The numbers of introns, exons and conserved sequences in all of the identified genes are different. In addition, 20 DoMYB genes from six subfamilies were selected for further analysis of tissue-specific expression and responses to various abiotic stresses treatments. The results showed that all of the DoMYB genes in S4 and S19 subfamilies exhibited the highest relative expression levels in flowers. And five DoMYB genes including DoMYB31 , DoMYB40 , DoMYB49, DoMYB52 and DoMYB54 , responded to the stress response. These results may provide useful information for further studies of the R2R3-MYB gene family.

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.
