<i>Arabidopsis LRR-MAL Receptor-like Kinases</i> regulate intraspecific and interspecific pollen-stigma interactions
Bibliographic record
Abstract
Abstract Flowering plants contain tightly controlled pollen-pistil interactions required for promoting intraspecies fertilization and preventing interspecies hybridizations. In Arabidopsis , several receptor kinases (RKs) are known to regulate the later stages of intraspecies pollen tube growth and ovular reception in the pistil, but less is known about RK regulation of the earlier stages. The Arabidopsis RKF1 cluster of Leucine-Rich Repeat Malectin ( LRR-MAL) RKs was previously found to function in the stigma to promote intraspecies pollen hydration. Here, we tested additional combinations of up to seven Arabidopsis LRR-MAL RK knockout mutants for the RKF1 cluster, LIK1 , RIR1 and NILR2 . These LRR-MAL RKs were discovered to function in the female stigma to support intraspecies Arabidopsis pollen tube growth and to establish a pre-zygotic interspecies barrier against Capsella rubella pollen. Thus this study uncovered new biological functions for these poorly understood group of RKs in regulating the early stages of Arabidopsis sexual reproduction.

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.
