Nuclear positioning and cell division site specification in plants
Bibliographic record
Abstract
The nucleus is a signature organelle present in eukaryotic cells, from plants to humans. Like any other organelle in the cell, the nucleus is dynamic and constantly moving. Nuclear movement can be directional depending on the cell type and its spatial and temporal function in the cell. During asymmetric cell division, the pre-mitotic nucleus moves directionally. A long-standing question in biology has been whether the nucleus determines the future cell division site, or if the future cell division site dictates the nuclear position. Plant cell biologists have done a fantastic job in answering this question over the years using classic genetic and cell biology approaches. Unfortunately, many classic experiments are fundamental for our understanding and not highlighted in recent literature. In this review, we cover classic experiments performed without novel molecular tools, and advance to recent experiments leveraging molecular and genetic tools. We provide a roadmap to understanding the importance of nuclear position in deciding the future cell division site.

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.
