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

backgroundThe bHLH transcription factor SD6 regulates rice seed dormancy. However, sequence variants of wheat SD6 homologs and their roles in seed dormancy remain unknown.

resultsHere, we cloned three wheat homologous genes of SD6 (named TaSD6-7A, TaSD6-7B, and TaSD6-7D), and found that TaSD6-7A had abundant sequence variations, while TaSD6-7B and TaSD6-7D had no variation. Based on sequence variations in the promoter and coding regions of TaSD6-7A, we developed three molecular markers and verified their associations with seed dormancy in 160 wheat varieties. We further confirmed that the TaSD6-7 A + 1307-T allele positively regulated seed dormancy, but had no adverse effects on other important agronomic traits. Resequencing and phenotypic data indicated that the favorable haplotype TaSD6-7A

conclusionOverall, this study provides novel genetic resources and molecular markers for improving PHS resistance of modern wheat varieties.
