High-density genetic map and genome-wide association studies of aesthetic traits in Phalaenopsis orchids.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Phalaenopsis spp. represent the most popular orchids worldwide. Both P. equestris and P. aphrodite are the two important breeding parents with the whole genome sequence available. However, marker-trait association is rarely used for floral traits in Phalaenopsis breeding. Here, we analyzed markers associated with aesthetic traits of Phalaenopsis orchids by using genome-wide association study (GWAS) with the F1 population P. Intermedia of 117 progenies derived from the cross between P. aphrodite and P. equestris. A total of 113,517 single nucleotide polymorphisms (SNPs) were identified in P. Intermedia by using genotyping-by-sequencing with the combination of two different restriction enzyme pairs, Hinp1 I/Hae III and Apek I/Hae III. The size-related traits from flowers were negatively related to the color-related traits. The 1191 SNPs from Hinp1 I/ Hae III and 23 simple sequence repeats were used to establish a high-density genetic map of 19 homolog groups for P. equestris. In addition, 10 quantitative trait loci were highly associated with four color-related traits on chromosomes 2, 5 and 9. According to the sequence within the linkage disequilibrium regions, 35 candidate genes were identified and related to anthocyanin biosynthesis. In conclusion, we performed marker-assisted gene identification of aesthetic traits with GWAS in Phalaenopsis orchids.
