Developmental innovation of inferior ovaries and flower sex orchestrated by KNOX1 in cucurbits.
Article in Nature plants, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
In flowering plants, inferior ovaries are key morphological innovations that evolved multiple times from superior ovaries to protect female parts of the flower. However, the developmental mechanisms underlying inferior ovary formation remain largely unknown. Comparative spatial transcriptome mapping and cell lineage reconstructions in developing floral buds of cucumber and tomato, which have inferior and superior ovaries, respectively, revealed that inferior ovaries develop from accelerated receptacle growth resulting from the continuous activity of meristematic stems cells at the base of the cucumber floral organs. Genetic knockout of a receptacle-specific KNOX1 transcription factor in cucumber caused arrest in receptacle growth and yielded bisexual flowers with superior ovaries similar to those of tomato. Here we provide developmental and mechanistic insights into inferior ovary formation and sex determination in cucurbits.
