The dynamic regulatory network of stamens and pistils in papaya.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundPapaya exhibits three sex types: female (XX), male (XY), and hermaphrodite (XY
resultsIn this study, we identified three organ-specific clusters involved in papaya pistils and stamens development. We found that pistil development is primarily characterized by the significant expression of auxin-related genes, while the pistil abortion genes in males is mainly associated with cytokinin, gibberellin, and auxin pathways. Additionally, we constructed expression regulatory networks for the development of female pistils, aborted pistils and stamens in male flowers, revealing key regulatory genes and signaling pathways involved in papaya organ development. Furthermore, we systematically identified 65 members of the MADS-box gene family and 10 ABCDE subfamily MADS-box genes in papaya. By constructing a phylogenetic tree of the ABCDE subfamily, we uncovered gene contraction and expansion in papaya, providing an improved understanding of the developmental mechanisms and evolutionary history of papaya floral organs.
conclusionsThese findings provide a robust framework for identifying candidate sex-determining genes and constructing the sex determination regulatory network in papaya, providing insights and genomic resources for papaya breeding.
