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

backgroundFlower size significantly influences the visitation of pollinators in angiosperms, and is also a crucial trait that affects commercial value of ornament plants. Sweet osmanthus (Osmanthus fragrans) is an ornamental species characterized by its small and aromatic flowers. GATA transcription factors have been reported to be involved in regulating plant development and growth. However, our understanding of the regulatory functions of GATA transcription factors concerning floral traits in ornamental plants such as sweet osmanthus remains limited.

resultsIn this study, we functionally identified a member of the GATA family,, designated as OfGATA9, in sweet osmanthus. The expression of OfGATA9 was found to be transcriptionally up-regulated during the early stages of flower opening in sweet osmanthus. Furthermore, the expression pattern of OfGATA9 correlated with the flower size across various cultivars of sweet osmanthus. The nucleus-localized OfGATA9 harbors a conserved GATA-type zinc finger domain, and belongs to subfamily I of the GATA family. Ectopic over-expression of OfGATA9 in Nicotiana tabacum resulted in an increase in both flower size and epidermis cell dimensions. Comparative transcriptome analysis between control and transgenic N. tabacum showed that over-expressing OfGATA9 led to differential expression of genes including EXLB1, XTHs, bHLHs, EFRs, Auxin/IAAs, SAURs, MYB-like, and MADS-box genes in flowers.

conclusionsThis study revealed the function of OfGATA9 in regulatory networks that influence flower size by promoting cell expansion and the expression of related genes. Our findings establish a theoretical foundation for breeding large-flowered sweet osmanthus.
