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

Direct-seeded rice is of great significance for ensuring food security. The hypoxic conditions under deep sowing impose significant abiotic stress to severely inhibit seed germination and seedling emergence in direct-seeded rice. Improvement of rice tolerance to deep-sowing germination stress is critical for promoting the seedling and grain yield of direct-seeded rice. In this study, we employed 276 rice germplasms to investigate the hypoxic germination (HG)-related traits through genome-wide association study (GWAS). Transcriptome profiling was conducted on germplasms with strong and weak HG tolerance under both deep-sowing and control conditions. GWAS identified 76 HG-associated genes, among which 27 genes were also detected by transcriptome profiling. Gene functional annotation and haplotype analysis screened four important candidate genes (LOC_Os01g51870, LOC_Os03g11510, LOC_Os05g01440, and LOC_Os07g35350) related to HG under deep sowing. The findings establish a genetic framework for improving HG tolerance in rice under deep sowing through molecular breeding strategies.
