Rapid formation of stable autotetraploid rice from genome-doubled F1 hybrids of japonica-indica subspecies.
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 11 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
Theory predicts that in the absence of selection, a newly formed segmental allopolyploid will become 'autopolyploidized' if homoeologous exchanges (HEs) occur freely. Moreover, because selection against meiotic abnormalities is expected to be strong in the initial generations, we anticipate HEs to be uncommon in evolved segmental allopolyploids. Here we analysed the whole-genome composition of 202 phenotypically homogeneous and stable rice tetraploid recombinant inbred lines (TRILs) derived from Oryza sativa subsp. japonica subsp. indica hybridization/whole-genome doubling. We measured functional traits related to growth, development and reproductive fitness, and analysed meiotic chromosomal behaviour of the TRILs. We uncover factors that constrain the genomic composition of the TRILs, including asymmetric parental contribution and exclusive uniparental segment retention. Intriguingly, some TRILs that have high fertility and abiotic stress resilience co-occur with largely stabilized meiosis. Our findings comprise evidence supporting the evolutionary possibility of HE-catalysed 'allo-to-auto' polyploidy transitions in nature, with implications for creating new polyploid crops.
