Natural allelic variation in SW14 determines seed weight and quality in soybean.

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
Seed weight and oil/protein content are critical agronomic traits that determine soybean yield and quality. However, the key genes controlling these traits and the underlying regulatory mechanisms remain poorly understood. Here, we performed a combination of genome-wide association study and quantitative trait loci (QTL) mapping with seed weight variations, and identified a Nuclear Factor-YA (NF-YA) gene on chromosome 14 that positively regulates seed weight and protein content while negatively regulating oil content without affecting other agronomic traits, designated as Seed Weight 14 (SW14). SW14 physically interacts with GmLEC1a/b, the soybean orthologs of the central regulator of plant seed development, Leafy Cotyledon1 (LEC1), to disrupt the formation of a non-canonical NF-Y complex comprising GmLEC1, GmNF-YC2, and GmbZIP67, thereby inhibiting the GmLEC1-mediated transcriptional activation involved in seed development process. Natural allelic variations in SW14 affect the stability of the SW14 protein, which in turn confers varied seed weight and oil/protein content in soybean. Further analysis demonstrates that the elite SW14
