Genome-wide analysis of Cyclophilin gene family in soybean (Glycine max)
Bibliographic record
Abstract
BACKGROUND: Cyclophilins (CYPs) belong to the immunophilin superfamily, and have peptidyl-prolyl cis-trans isomerase (PPIase) activity. PPIase catalyzes cis- and trans-rotamer interconversion of the peptidyl-prolyl amide bond of peptides, a rate-limiting step in protein folding. Studies have demonstrated the importance of many PPIases in plant biology, but no genome-wide analysis of the CYP gene family has been conducted for a legume species. RESULTS: Here we performed a comprehensive database survey and identified a total of 62 CYP genes, located on 18 different chromosomes in the soybean genome (GmCYP1 to GmCYP62), of which 10 are multi- and 52 are single-domain proteins. Most of the predicted GmCYPs clustered together in pairs, reflecting the ancient genome duplication event. Analysis of gene structure revealed the presence of introns in protein-coding regions as well as in 5' and 3' untranslated regions, and that their size, abundance and distribution varied within the gene family. Expression analysis of GmCYP genes in soybean tissues displayed their differential tissue specific expression patterns. CONCLUSIONS: Overall, we have identified 62 CYP genes in the soybean genome, the largest CYP gene family known to date. This is the first genome-wide study of the CYP gene family of a legume species. The expansion of GmCYP genes in soybean, and their distribution pattern on the chromosomes strongly suggest genome-wide segmental and tandem duplications.

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.
