Ginger genome reveals the SMPED1 gene causing sex-phase synchrony and outcrossing in a flowering plant.
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 2 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 many flowering plants, male and female reproductive organs mature at different times to avoid self-pollination, a phenomenon termed dichogamy. Most dichogamous species are either protandrous or protogynous, making this strategy difficult to study genetically. However, in the ginger Alpinia mutica, protandrous and protogynous floral morphs co-occur within populations, and the synchronized rhythmic movement of styles and dehiscence of stamens promotes cross-pollination between morphs. Here we demonstrate that a single Mendelian locus with a dominant allele governing protogyny controls sexual polymorphism. We used haplotype-resolved genomes and population genomics to identify the dichogamy-determining region, revealing a large deletion in the protandrous morphotype. We found that the key gene SMPED1, located adjacent to the deletion, governs the timing of anther dehiscence and style movement. SMPED1 is widespread among angiosperms and probably has conserved function. Our findings represent a new genetic characterization of a key mating system gene controlling the synchrony of sex organs in flowering plants.
