Dynamic proteomics reveals that endosperm weakening plays a critical role during seed germination in

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Methods: This study employed iTRAQ-based proteomics, transcriptomics, and hormone profiling to analyze three key germination stages (S1, pulp removal and initial imbibition. S2, radicle emergence through the seed coat. S3, transition phase between primary root elongation and cotyledon emergence). Results: Morphological observations indicated gradual endosperm weakening and embryo development during germination. Transcriptomics highlighted 30 enriched pathways, notably plant hormone signaling and starch and sucrose metabolism. Proteomics revealed consistent enrichment of FOG: RRM domain, aspartyl protease, and β-fructofuranosidase across comparisons. Hormone assays showed decreases in ABA, bioactive GAs, IAA, JA, and SA from S1 to S3, with a marked increase in the bioactive GAs/ABA ratio. Integrated omics emphasized metabolism and hormone signal transduction. Key enzymes in starch and sucrose metabolism (e.g., β-fructofuranosidase, α-xylosidase, β-D-xylosidase, and β-glucosidase) increased, supporting energy conversion and endosperm weakening. Conversely, ABA-related proteins (PYL4, PP2C) decreased. Sucrose synthase, involved in ABA-GA antagonism, also declined. Discussion: These results underscore synergistic endosperm weakening and hormonal regulation during
