Bibliographic record
Abstract
Shi, H., Wang, Y., Li, Z., Zhang, D., Zhang, Y., Xiang, D., Li, Y. and Zhang, Y. 2014. Pear IAA1 gene encoding an auxin-responsive Aux/IAA protein is involved in fruit development and response to salicylic acid. Can. J. Plant Sci. 94: 263–271. Auxin-responsive Aux/IAA proteins are rapidly auxin-induced, short-lived proteins that act as repressors for the auxin response factor (ARF)-activated gene expression. A gene encoding an Aux/IAA protein and designated PpIAA1 was isolated from pear (Pyrus pyrifolia). Using PCR amplification techniques, the genomic clone corresponding to PpIAA1 was isolated and shown to contain three introns with typical GT/AG boundaries defining the splice junctions. The deduced PpIAA1 protein contains the conserved features of indole-3-acetic acids (IAA): four Aux/IAA conserved domains, Aux/IAA family domain, Aux/IAA-ARF dimerization domain profile, and conserved nuclear localization signal (NLS) motifs. Phylogenetic analyses clearly demonstrated PpIAA1 has the highest homology with grape VvIAA. PpIAA1 was preferentially expressed in fruit, and moderate expression was found in anthers. Relatively low expression signal was detected in other tissues including shoots, leaves, and petals. Moreover, expression of PpIAA1 was developmentally regulated in fruit. Further study demonstrated that PpIAA1 expression in pear fruit was remarkably regulated by salicylic acid and IAA. The data suggest that PpIAA1 might be involved in the interplay between IAA and salicylic acid signaling pathway during the fruit development of pear.

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.
