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

backgroundTassel branch number shapes plant architecture, which is crucial for maize adaptation to high-density planting. Therefore, unrevealing the molecular mechanisms of tassel branching is essential for crop breeding. To gain better insights into this mechanism, we integrated metabolomic and transcriptomic analysis to explore differentially accumulated metabolites (DAMs) and differentially expressed genes (DEGs) between two types of materials with distinct tassel branching numbers.

resultsWe identified a pair of maize sibling lines, unbranched tassel line (UBT) and multibranched tassel line (MBT). UBT has only one spike without branches due to the inhibition of branch meristems, while MBT has multiple branches. Gene Ontology (GO) enrichment analysis of DEGs revealed significant enrichment in organ growth regulation, hormone response and auxin signaling pathway. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of DAMs revealed enrichment in plant hormone signal transduction. Integrated transcriptomic and metabolomic analysis revealed enrichment of the tryptophan metabolism, a crucial auxin biosynthetic pathway, suggesting its potential involvement in tassel branching development.

conclusionsThe elevated levels of indole-3-acetamide in the tryptophan metabolism pathway suggest an increase in auxin accumulation, which may subsequently suppressed branch meristem formation in UBT through downregulation of BARREN STALK 1 expression and modulation of auxin signaling pathways.
