Ultrastructure of mesophyll cells in two Robinia pseudoacacia hybrids under NaCl stress
Bibliographic record
Abstract
The ultrastructural changes of mesophyll cells in two Robinia pseudoacacia hybrids,i.e.tetraploid R.pseudoacacia and diploid R.pseudoacacia,were observed under NaCl stress.The results showed that: 1) before salt stress,the chloroplasts of two R.pseudoacacia were morphologically integrated.After 10 days of stress,the chloroplast of diploid R.pseudoacacia began deformed,with ambiguity in membrane and disorganization in grana lamell.After 20 days,the chloroplast showed further swelling and disarrangement,with a clear degradation of membrane.For tetraploid R.pseudoacacia,the structure of chloroplast changed little after 10 and 20 days of stress;2) Before salt stress,the mitochondria of two R.pseudoacacia were morphologically integrated.After 10 days of stress,the cavitas and ambiguous crista were observed in the mitochondria of diploid R.pseudoacacia,which appeared ambiguity in membrane and lost integrity.After 20 days,most of mitochondria lost complete membrane and showed compatible with cytoplasm;no clear cristae but many cavitas were observed.The mitochondria of tetraploid R.pseudoacacia changed little with salt stress;3 ) Before salt stress,the mesophyll cell of two R.pseudoacacia showed loose arrangement and complete structure.The chloroplast distributed at the margin of the cell wall.After 10 days,parts of chloroplast in diploid R.pseudoacacia moved to the middle of cell.After 20 days,most of chloroplast located in the middle of cell and showed random distribution;cell membrane degraded partly and became ambiguity.The shape of mesophyll cell of tetraploid R.pseudoacacia changed little under salt stress.The above results indicate that tetraploid R.pseudoacacia has anatomic adaptation to the salt stress.

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.
