1 · What the graph read from it

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.

2 · The registry

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

key messageA novel GLK transcription factor, BnaA03.G2-like, regulates seed vigor after aging by affecting FAs composition in B. napus. Seeds, a most crucial materials for crop production, constitute the basis of agriculture. Seed aging usually occurs during storage, especially for seeds with high oil content. However, the genes and mechanisms underlying seed aging in Brassica napus, a widely grown oilseed crop, remain largely unexplored. In this study, nine SNPs associated with seed vigor after aging were identified through a genome-wide association study, and transgenic seeds confirmed that BnaA03.G2-like negatively regulated seed vigor after aging. Haplotype and gene-based association analyses revealed that S_A3.16900957 and S_A3.16901008 were two core variants located within BnaA03.G2-like. Transcriptome analysis and gas chromatography results suggested that BnaA03.G2-like regulated fatty acid biosynthesis, and the linoleic acid content significantly increased in the seeds of BnaA03.G2-like overexpression lines but decreased in the seeds of BnaA03.G2-like RNA interference lines. Further correlation analysis and malondialdehyde determination revealed that BnaA03.G2-like regulated seed vigor by affecting the linoleic acid content in mature seeds and the degree of membrane lipid peroxidation during seed aging. This study initially reported the function of BnaA03.G2-like and its favorable alleles, providing genetic resources for seed antiaging breeding in B. napus.
