Transcriptome-wide association study and eQTL analysis to assess the genetic basis of bulb-yield traits in garlic (Allium sativum).
Article in BMC genomics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
backgroundGarlic bulbs are abnormal expanding axillary buds that are rarely found among vascular plants. Bulb-yield is one of the valuable agronomic traits of garlic. However, due to the large genome size and a strictly asexual life cycle in the cultivars, the genetic basis of the yield traits are poorly understood in garlic.
resultsIn the present study, we carried out an association mapping for three yield traits of garlic bulbs: bulb weight (BW), diameter (BD), and the number of garlic cloves (CN), using the recently proposed transcriptome-referenced association study. In total 25, 2, and 30 single nucleotide polymorphisms (SNPs), were identified in the transcripts to be associated with BW, BD, and CN traits, respectively. Of the transcripts with associated SNPs, the expression of 17 of them showed a significant correlation with the corresponding traits in the population, suggesting their relation to bulbs yield traits. Six transcripts were long non-coding RNAs (lncRNAs), and the others encode proteins involved mainly in carbohydrate metabolism, transcription regulation, cytokinin activity, protein degradation, etc. In addition, expression quantitative trait locus (eQTL) and expression correlation analysis have revealed that seven CN-related transcripts displayed interrelation, constituting two potential pathways.
conclusionThis study provides novel insights into the genetic basis of the yield traits in garlic bulbs, and the identification of trait-associated SNPs/transcripts provides a basis for improving the bulb yield in garlic breeding.
