Structure-function analysis of the barley genome: the gene-rich region of chromosome 2HL.
Article in Functional & integrative genomics, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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.
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
A major gene-rich region on the end of the long arm of Triticeae group 2 chromosomes exhibits high recombination frequencies, making it an attractive region for positional cloning. Traits known to be controlled by this region include chasmogamy/cleistogamy, frost tolerance at flowering, grain yield, head architecture, and resistance to Fusarium head blight and rusts. To assist these cloning efforts, we constructed detailed genetic maps of barley chromosome 2H, including 61 polymerase chain reaction markers. Colinearity with rice occurred in eight distinct blocks, including five blocks in the terminal gene-rich region. Alignment of rice sequences from the junctions of colinear chromosome segments provided no evidence for the involvement of long (>2.5 kb) inverted repeats in generating inversions. However, reuse of some junction sequences in two or three separate evolutionary breakage/fusion events was implicated, suggesting the presence of fragile sites. Sequencing across 91 gene fragments totaling 107 kb from four barley genotypes revealed the highest single nucleotide substitution and insertion-deletion polymorphism levels in the terminal regions of the chromosome arms. The maps will assist in the isolation of genes from the chromosome 2L gene-rich region in barley and wheat by providing markers and accelerating the identification of the corresponding points in the rice genome sequence.
