The pomegranate (Punica granatum L. cv. 'Wonderful') genome and P. protopunica shed light on pomegranate domestication. Is Daru a wild stock?

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
backgroundThe pomegranate is cultivated across a wide range of geographical regions worldwide for ornamental purposes, fruit aril for the food industry, and juice production. The pomegranate genome is reported to consist of 2n = 16 chromosomes in some cultivars and 2n = 18 in others. Clustering assembled contigs using Hi-C technology resulted in eight pseudochromosomes, alternatively, anchoring these contigs onto a genetic map produced nine pseudochromosomes. The origin of the domesticated pomegranate is unknown. Previous studies have suggested that the variant Daru, which is grown in the region of India and Nepal, is the origin of the wild stock.
resultsHere we explored the phylogeny, genetic structure, and substitution pattern of P. granatum. Phylogenetic analysis of Punica granatum accessions revealed that Daru seedlings constitute a distinct clade, which is a sister to the clade of Asian accessions, rather than an outgroup. No evidence of introgression was observed between Daru and cultivated accessions. Analysis of the non-synonymous to synonymous substitutions ratio in genic regions outlines a similar profile of the Daru and the domesticated pomegranates with overall positive selection, while the wild type P. protopunica illustrated a different profile with positive selection only in some regions. Domesticated pomegranate variants show low heterozygosity and nucleotide diversity, particularly on chromosome 1.
conclusionsOur findings suggest that differences in chromosome numbers may be associated with the formation of chromosome quadrivalents and their impact on the arrangement of contigs into pseudochromosomes. The profile of Kn to Ks ratio in domesticated pomegranates likely reflects positive selection. Genetic profiling of Daru, domesticated P. granatum, and wild-type P. protopunica revealed that Daru more closely resembles domesticated plants, challenging the notion that it represents the wild pomegranate.
