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

backgroundCowpea is one of the most important legume crops in the world. Flowering time (FT) and growth habit (GH) are fundamentally important in determining cowpea yield. However, the genetic basis of nature variation in FT and GH has been seldom explored.

resultsIn this study, we evaluated the FT and GH of a genetic diversity panel of 344 cowpea accessions within two experimental replications in 2022 Spring and 2023 Autumn, respectively. We investigated their phenotypic variation and the distribution in three cowpea subpopulations. The FT varied from 53 to 70 days and 30-65 days in 2022 spring and 2023 autumn, respectively. Prostrate type accounted for 92% (315 accessions) and the erect type only made up 4% (14 accessions). We identified 6 genomic regions significantly associated with FT and 14 regions controlling GH through genome-wide association study, respectively. Haplotype analysis confirmed the correlation between different haplotypes and the corresponding phenotypes. We also found the pyramiding effect of the favorable alleles on FT and GH. In addition, six candidate genes were regarded as the likely candidate genes for 6 significant regions, which may involve in the hormone signaling, transcription factor and various metabolic pathways.

conclusionsThese results enhanced our understanding of genetic mechanism of FT and GH, and facilitate the development of new varieties with correct flowering time and ideal growth habit.
