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

MAIN

conclusionThe distribution of early flowering alleles of VRN-A3 was found to be biased to low latitudes, and these alleles may contribute to environmental adaptability to low latitudes in cultivated emmer wheat. In wheat (Triticum spp.), the flowering time is an important trait for successful seed production and yield by adapting to the regional environment. An early flowering allele of VRN-A3 with 7- and 25-bp insertions in the promoter region (Vrn-A3a-h1) has recently been reported from the analysis of an emmer wheat (Triticum turgidum L. ssp. dicoccum) accession, TN26. This early flowering allele of VRN-A3 might be associated with the regional adaptation of wheat. In this study, we elucidated its geographic distribution to assess the importance of the early flowering allele of VRN-A3 in worldwide wheat collection. From sequence analysis, we identified six VRN-A3 alleles with the 7- and 25-bp insertions, namely, Vrn-A3a-h2, Vrn-A3a-h3, Vrn-A3a-h4, Vrn-A3a-h5, Vrn-A3a-h6, and Vrn-A3c-h2 from wild emmer wheat, while we identified two VRN-A3 alleles with these insertions, Vrn-A3a-h2 and Vrn-A3c-h1 from cultivated tetraploid and hexaploid wheat species in addition to Vrn-A3a-h1. Among VRN-A3 alleles distributed in cultivated wheat, we found that Vrn-A3a-h2 promoted early heading, whereas Vrn-A3c-h1 did not affect heading time. Our analysis showed that the distribution of early flowering alleles of VRN-A3 dominated in cultivated emmer wheat in Ethiopia and India, which actually showed an early flowering phenotype. This implied that the early flowering alleles of VRN-A3 contribute to adaptability to a low-latitude environment in cultivated emmer wheat. We could not find durum (T. turgidum L. ssp. durum) and bread wheat (T. aestivum L. ssp. aestivum) accessions with these early flowering alleles. Our findings indicated that Vrn-A3a-h1 and Vrn-A3a-h2 were useful for breeding of early flowering cultivars in durum and bread wheat varieties.
