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

Heterosis has long been exploited for crop breeding; however, the genetic mechanisms, particularly the initial establishment of heterosis during the early vegetative growth phase, remain elusive. The biggest challenge for that is to exclude noise genes from the identified heterosis-related candidates. Herein, we use nutrient-deficient hybrid with no measurable growth heterosis as control. After filtering these irrelevant genes, only 336 differentially expressed genes (DEGs), which is significantly lower than in previous reports, were identified as heterosis-related genes in a superhybrid rice of Liang-You-Pei-Jiu (LYP9) at early-tillering stage. Among the DEGs that could be mapped to quantitative trait loci (QTL), approximately 72.8% could be covered by yield or growth vigor-related QTL, thereby suggesting that our DEGs were reliable and may have potential value to rice breeding. Among the 336 DEGs identified, a majority showed intermediate expression relative to that of its parental lines (i.e. additive effects), particularly, expression was frequently more similar to the paternal line rather than the maternal line (44.1% versus 32.7%); the remaining 27.1% were exclusively up- or down-regulated between the hybrid and either parent. Interestingly, up-regulated genes encoded various enzymes, whereas down-regulated genes were enriched in responses to stress, indicating that hybrids may benefit from both activating metabolism-related pathways and alleviating fitness cost through allelic interactions. Furthermore, a significantly larger proportion of divergent genes and higher nonsynonymous substitutions rates were detected in these DEGs, suggesting a potential contribution to the establishment of heterosis in superhybrid rice LYP9.
