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

Chromosome 1H (approximately 622 Mb) of barley (Hordeum vulgare) was isolated by flow sorting and shotgun sequenced by GSFLX pyrosequencing to 1.3-fold coverage. Fluorescence in situ hybridization and stringent sequence comparison against genetically mapped barley genes revealed 95% purity of the sorted chromosome 1H fraction. Sequence comparison against the reference genomes of rice (Oryza sativa) and sorghum (Sorghum bicolor) and against wheat (Triticum aestivum) and barley expressed sequence tag datasets led to the estimation of 4,600 to 5,800 genes on chromosome 1H, and 38,000 to 48,000 genes in the whole barley genome. Conserved gene content between chromosome 1H and known syntenic regions of rice chromosomes 5 and 10, and of sorghum chromosomes 1 and 9 was detected on a per gene resolution. Informed by the syntenic relationships between the two reference genomes, genic barley sequence reads were integrated and ordered to deduce a virtual gene map of barley chromosome 1H. We demonstrate that synteny-based analysis of low-pass shotgun sequenced flow-sorted Triticeae chromosomes can deliver linearly ordered high-resolution gene inventories of individual chromosomes, which complement extensive Triticeae expressed sequence tag datasets. Thus, integration of genomic, transcriptomic, and synteny-derived information represents a major step toward developing reference sequences of chromosomes and complete genomes of the most important plant tribe for mankind.
