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

Amphicarpy (seed heteromorphy) is a unique and fascinating reproductive strategy wherein a single plant produces both aerial and subterranean fruits. This strategy is believed to be an adaptation to life under stressful or uncertain environments. Here, we sequenced and de novo assembled a chromosome-level genome assembly of the legume Amphicarpaea edgeworthii Benth. The 299-Mb A. edgeworthii genome encodes 27 899 protein-coding genes and is the most compact sequenced legume genome reported until date. Its reduced genome size may be attributed to the reduced long-terminal repeat retrotransposon content, which stems from the unequal homologous recombination. Gene families related to immunity and stress resistance have been contracted in A. edgeworthii, which is consistent with the notion that the amphicarpic reproductive strategy may be a complementary mechanism for its weak environmental-adaptation ability. We demonstrated the 'ABCE' model for the differentiation of chasmogamous and cleistogamous flowers. In addition, the characteristics of aerial and subterranean seeds in hard-seededness were explored. Thus, we suggest that the A. edgeworthii genome, which is the first of an amphicarpic plant, offers significant insights into its unusual reproductive strategy that is a key resource towards comprehending the evolution of angiosperms.
