Genome-Wide Association Study in European Beech (Fagus sylvatica L.) for Drought Stress Related Traits.
Article in Physiologia plantarum. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Genome-wide association studies (GWAS) aim to identify loci associated with different traits, which could be evaluated in subsequent studies and later be prioritized in individual and seed stand selection. In trees, traits are measured at maturity or are only available after a long time, and juvenile-mature correlations are often unknown. Therefore, it is a promising approach to study natural populations directly. Data were collected from approximately 100 adult beech trees per stand in five locations in the Postăvarul Massif, South-Eastern Romanian Carpathians (Carpații de Curbură) along an altitudinal gradient associated with precipitation and temperature. We performed GWAS on 610,678 single-nucleotide polymorphisms (SNPs) using PLINK and Genome-wide Efficient Mixed Model Association (GEMMA) to identify SNP markers associated with drought-stress-related traits. Even though this study used a natural population, we found very interesting associations while accounting for environmental heterogeneity along the altitudinal gradient. A total of 88 markers were associated with stomatal density. Seventy-two markers are located on chromosome 10 in a region spreading from ~5.48 to 13.67 Mb. We found five gene annotations in this region that are thought to play a role in controlling stomatal density in Arabidopsis. All markers within this region exhibit similar allele frequencies, which indicate a connection to stomatal density and the altitudinal gradient. This entire region may be under joint selection for stomatal features. Our research provides insights into the genetic architecture of various drought-stress traits in the studied population.
