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

key messageThe divergence patterns of NBS - LRR genes in soybean Rsv3 locus were deciphered and several divergent alleles ( NBS_C, NBS_D and Columbia NBS_E ) were identified as the likely functional candidates of Rsv3. The soybean Rsv3 locus, which confers resistance to the soybean mosaic virus (SMV), has been previously mapped to a region containing five nucleotide binding site-leucine-rich repeats (NBS-LRR) genes (referred to as nbs_A-E) in Williams 82. In resistant cultivars, however, the number of NBS-LRR genes in this region and their divergence from susceptible alleles remain unclear. In the present study, we constructed and screened a bacterial artificial chromosome (BAC) library for an Rsv3-possessing cultivar, Zaoshu 18. Sequencing two positive BAC inserts on the Rsv3 locus revealed that Zaoshu 18 possesses the same gene content and order as Williams 82, but two of the NBS-LRR genes, NBS_C and NBS_D, exhibit distinct features that were not observed in the Williams 82 alleles. Obtaining these NBS-LRR genes from eight additional cultivars demonstrated that the NBS_A-D genes diverged into two different alleles: the nbs_A-D alleles were associated with the rsv3-type cultivars, whereas the NBS_A-D alleles were associated with the Rsv3-possessing cultivars. For the NBS_E gene, the cultivar Columbia possesses an allele (NBS_E) that differed from that in Zaoshu 18 and rsv3-type cultivars (nbs_E). Exchanged fragments were further detected on alleles of the NBS_C-E genes, suggesting that recombination is a major force responsible for allele divergence. Also, the LRR domains of the NBS_C-E genes exhibited extremely strong signals of positive selection. Overall, the divergence patterns of the NBS-LRR genes in Rsv3 locus elucidated by this study indicate that not only NBS_C but also NBS_D and Columbia NBS_E are likely functional alleles that confer resistance to SMV.
