Divergence of VRN-B3 alleles during the evolution of domesticated wheat.

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
Genetic changes accrued during the domestication of wheat have been crucial in improving the cultivation and yield of this strategic crop. Allelic variation at the VRN3 gene makes a significant contribution to the adaptability of wheat to a wide range of environmental conditions. In the present study, the origin and distribution of the Vrn-B3a and Vrn-B3b alleles during the evolution of wheat were investigated. Analysis of 214 accessions of 11 polyploid wheat species from different eco-geographical areas found the Vrn-B3a and Vrn-B3b alleles in accessions of tetraploid wheat T. dicoccum from Russia and hexaploid wheat of T. spelta from Iran, respectively. DNA sequence analysis of an insertion in the Vrn-B3b promoter region identified a new family of non-autonomous transposable hAT elements that originated in T. urartu lineage. Publicly available whole genome sequence assemblies of 11 T. aestivum and T. durum varieties, as well as WGS of T. dicoccoides were used to investigate the phylogeny and distribution of the TEs inserted in the Vrn-B3a and Vrn-B3b promoter regions, to determine the origin of these alleles. Results showed that both Vrn-B3a and Vrn-B3b diverged during the domestication of wheat, in the T. dicoccum lineage. However, while Vrn-B3a is common in T. dicoccum and T. durum from Ukraine and Russia the Vrn-B3b allele likely has a more recent origin in hexaploid wheat from the Near East.
