Abstract
Wu, Q., Wang, X. Z., Tang, Y. Y., Yu, H. T., Cui, F. G., Zhang, J. C. and Wang, C. T. 2014. Molecular cloning, genomic organization and functional analysis of the ribosomal protein L4/L1 (RPL4) gene from Arachis hypogaea. Can. J. Plant Sci. 94: 85–97. The ribosomal proteins have been shown to be important in plant polarity establishment, cell proliferation, leaf shape and auxin-related development. The RPL4 protein is crucial for the maintenance of ribosomal translational efficiency and fidelity. This study concerns the RPL4 gene from Arachis hypogaea. The full-length cDNA (1538 bp) of RPL4 consisted of an open-reading frame of 1221 bp encoding 406 amino acids. The genomic DNA sequence of RPL4 gene consisted of 1491 bp containing two exons and one 270-bp intron. The RPL4 mRNA transcript was mainly expressed in roots and leaves, and fewer signals were detected in stems. The sequence data revealed that RPL4 encoded a typical ribosomal protein L4/L1e domain. Phylogenetic analysis for genes encoding proteins showed that RPL4 were conserved within dicotyledonous and monocotyledonous plants. The ratios of nonsynonymous/synonymous substitution rate (ω=d N/d S) were analyzed. No sites were identified under positive selection. In the whole RPL4 sequence, d S greatly exceeded d N in all branches of the tree (d N/d S<< 1.0), indicating that functional constraints (purifying selection) have acted on RPL4 throughout evolution. The differences among plants and animals and Caenorhabditis elegans may indicate functional differentiation during species evolution.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
