Gamma-aminobutyric acid (GABA) releases seed dormancy by orchestrating abscisic acid and gibberellin metabolism and signaling.

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
backgroundSeed dormancy release, regulated by abscisic acid (ABA) and gibberellin (GA), is essential for plant development and yield. Gamma-aminobutyric acid (GABA) is known to mediate plant stress responses; however, its role in seed dormancy release remains elusive.
resultsHere, we reported that seed dormancy release was impaired in GAD2-deficient seeds lacking GABA biosynthesis while enhanced in GABA-T-deficient seeds with impaired GABA catabolism, indicating a positive regulatory role of GABA in seed dormancy release. Further, ABA antagonized GABA-facilitated seed dormancy release, and GABA failed to alleviate seed dormancy in the GA-deficient mutant ga1-t. Analysis of mutants defective in ABA and GA biosynthesis revealed that seed dormancy release, characterized as decreased ABA content and increased GA
conclusionOur findings not only advance our understanding on the mechanism of GABA-mediated seed dormancy release via coordinated regulation of abscisic acid and gibberellin pathways, but also highlight the potential of GABA as a natural alternative to synthetic chemicals for promoting sustainable and environmentally friendly agricultural practices.
