Glycosylation of S-RNases may influence pollen rejection thresholds in<i>Solanum chacoense</i>
Bibliographic record
Abstract
A survey of Solanum chacoense plants expressing an authentic S(11)-RNase transgene identified a line with partial compatibility to S(11) pollen. By comparing fruit set to the S-RNase levels determined immunologically in single styles, the minimum level of S(11)-RNase required for full rejection of S(11) pollen was estimated to be 18 ng per style. The S(11)-RNase threshold levels are thus considerably lower than those previously reported for the S(12)-RNase. Interestingly, these two allelic S-RNases differ dramatically in the extent of glycosylation, with the number of glycosylation sites varying from one (S(11)-RNase) to four (S(12)-RNase). It is suggested that reduced glycosylation of the S(11)-RNase may be related to the lower threshold for pollen rejection.

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.
