Abstract
Significance Interorganelle connectivity and nonvesicular information transfer are hallmarks of biological systems. These processes facilitate communication between organelles, allowing them to adapt to changing cellular environments. In plants, the endoplasmic reticulum (ER)–plasma membrane (PM) contact sites (EPCSs) physically connect the cortical ER and the PM, and act as general platforms for Ca 2+ homeostasis regulation and the cellular adaptation to environmental stresses. Our identification of ionic stress and PM phosphoinositides as enhancers of ER–PM connectivity advances our understanding of how stress influences interorganelle communication. Furthermore, our analyses of the spatiotemporal regulation of EPCS expansion highlights unique mechanisms that plants activate to maintain interorganelle communication during long-term exposure to environmental stress, not described in other eukaryotes.

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 it
