Editorial: Advances in Pollen Research: Biology, Biotechnology, and Plant Breeding Applications
Bibliographic record
Abstract
In flowering plants, mature pollen grains are produced within the developing anthers of the flowers in two successive phases, microsporogeneseis and microgametogenesesis.Anther and pollen development involves the coordinated growth and differentiation of tissues and cell types required for the formation of viable male gametes, but also, to permit pollen release and ensure successful fertilization. The identification of the genetic networks and regulatory molecules involved in the formation of the anther remains a highly unexplored topic in many crops. Evolutionary and functional studies in crops are helping to unravel new functions for genes originally identified in model plants (Rojas-Gracia et al. 2017) and the changes in transcriptional profiles associated with plant domestication (Xiang et al. 2019). Under the global changes in environmental conditions, pollen development is probably one of the most vulnerable and challenged stages of plant reproduction (Chaturvedi et al. 2021). In this context, increasing basic research will provide valuable information to assist the design of biotechnological tools to mitigate this effect especially in crop systems in the future. All authors contributed to the article and approved the final version of the manuscript.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
