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

backgroundRye (Secale cereale L.) is the most widely used related species in wheat genetic breeding, and the introduction of its chromosome fragments into the wheat genome through distant hybridization is essential for enriching the genetic diversity of wheat. Rapid and accurate detection of rye chromatin in the wheat genome is important for distant hybridization. Simple sequence repeats (SSRs) are widely distributed in the genome, and SSRs of different species often exhibit species-specific characteristics.

resultsIn this study, genome-wide SSRs in rye were identified, and their characteristics were outlined. A total of 997,027 SSRs were selected, with a density of 115.97 SSRs/Mb on average. There was no significant difference in the number of SSRs on each chromosome. The number of SSRs on 2R was the highest (15.29%), and the number of SSRs on 1R was the lowest (13.02%). The number of SSRs on each chromosome is significantly correlated with chromosome length. The types of SSR motifs were abundant, and each type of SSR was distributed on 7 chromosomes of rye. The numbers of mononucleotide simple sequence repeats (MNRs), dinucleotide simple sequence repeats (DNRs), and trinucleotide simple sequence repeats (TNRs) were the greatest, accounting for 46.90%, 18.37%, and 22.64% of the total number, respectively. Among the MNRs, the number of G/C repeats and the number of 10 bp motifs were the greatest, accounting for 26.24% and 31.32% of the MNRs, respectively. Based on the SSR sequences, a total of 657 pairs of primers were designed. The PCR results showed that 119 pairs of these primers were rye-specific and could effectively detect rye chromatin in the wheat genome. Moreover, 86 pairs of the primers could also detect one or more specific rye chromosomes.

conclusionThese results lay a foundation for both genomic evolution studies of rye and molecular breeding in wheat.
