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

backgroundMaize, as an important dual-purpose grain and forage crop all over the world, exhibits extensive heritable and phenotypic diversity. Taking the breeding patterns as the core and developing advanced genetic breeding tools with the characteristics of Chinese maize germplasms will significantly advance the genetic dissection of complex agronomic traits and facilitate targeted genetic improvement in maize.

resultsHere, based on the predominant heterotic pattern "X group × SPT group," we developed the first whole chromosome substitution line (WCSL) population in maize, designated the MOSAIC population. We ensured the near-complete substitution of single chromosome and consistent genetic backgrounds as much as possible in each WCSL from the MOSAIC population. The de novo genome assembly and characteristic analysis of the parental lines revealed abundant genetic variants between WCSLs and their parents. Three key major QTL loci associated with tassel main axis length, anthocyanin accumulation at the base of anther glumes, and tassel branch number were rapidly identified and mapped using the MOSAIC population. Meanwhile, we established the MOSAIC molecular breeding and data sharing platform (MOSAIC-DB), which integrates diverse data resources including pedigrees, phenotypes, genotypes, assembled genomes, and structural variants along with integrated analysis modules.

conclusionsThis study provides a powerful new genetic resource for uncovering the genetic basis of complex traits and for genetic improvement, which facilitates the exploration of the molecular mechanisms underlying key agronomic traits and enables more directed breeding strategies by integrating genetics and genomics in maize.
