Genetic regulation of rice minor vein patterning by the OsIDD14/12/13 protein complex
Bibliographic record
Abstract
INDETERMINATE DOMAIN (IDD) transcription factors play important and diverse roles in plant growth, development, and stress responses. For example, OsIDD12 and OsIDD13 associate with SHORT ROOT transcription factors to mediate the expression of the auxin influx transporter gene OsPIN5c in rice ( Oryza sativa ), thereby regulating minor vein differentiation. However, the underlying mechanism is unclear. In this study, we demonstrate that OsIDD14 associates with OsIDD12 and OsIDD13 to regulate minor vein patterning in rice. In situ hybridization and GUS reporter assays revealed that OsIDD14 expression is restricted to the rice vasculature. The osidd12 osidd13 osidd14 triple mutant exhibited a minor vein pattern similar to that of C 4 grasses. We demonstrate that OsIDD14 forms a heterogeneous protein complex with OsIDD12 and OsIDD13 that suppresses OsPIN5c expression and inhibits minor vein formation. Ectopic expression of OsIDD14 rescued the phenotypes of the osidd12 osidd13 double mutant, revealing the functional redundancy of rice IDD12, 13, and 14. In summary, these study reveals that OsIDD14 plays a pivotal role in minor vein patterning and has pleiotropic functions in rice, and laying the foundation for developing rice with high vein density.

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.
