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

The proper use of resistance genes (R genes) requires a comprehensive understanding of their genomics and evolution. We analyzed genes encoding nucleotide-binding sites and leucine-rich repeats in the genomes of rice (Oryza sativa), maize (Zea mays), sorghum (Sorghum bicolor), and Brachypodium distachyon. Frequent deletions and translocations of R genes generated prevalent presence/absence polymorphism between different accessions/species. The deletions were caused by unequal crossover, homologous repair, nonhomologous repair, or other unknown mechanisms. R gene loci identified from different genomes were mapped onto the chromosomes of rice cv Nipponbare using comparative genomics, resulting in an integrated map of 495 R loci. Sequence analysis of R genes from the partially sequenced genomes of an African rice cultivar and 10 wild accessions suggested that there are many additional R gene lineages in the AA genome of Oryza. The R genes with chimeric structures (termed type I R genes) are diverse in different rice accessions but only account for 5.8% of all R genes in the Nipponbare genome. In contrast, the vast majority of R genes in the rice genome are type II R genes, which are highly conserved in different accessions. Surprisingly, pseudogene-causing mutations in some type II lineages are often conserved, indicating that their conservations were not due to their functions. Functional R genes cloned from rice so far have more type II R genes than type I R genes, but type I R genes are predicted to contribute considerable diversity in wild species. Type I R genes tend to reduce the microsynteny of their flanking regions significantly more than type II R genes, and their flanking regions have slightly but significantly lower G/C content than those of type II R genes.
