Genetic diversity and morphological variation in wild Silene compacta Fischer genotypes from Türkiye.
Article in BMC plant biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Silene compacta Fischer ex Hornem., a member of Caryophyllaceae family, is a wild plant with significant ornamental and ecological value, now threatened by habitat loss and climate change. This study assessed the genetic diversity of 40 S. compacta genotypes collected from four—geographically distinct regions of Türkiye (Bolu, İzmir, Isparta, and Nevşehir) using 26 morphological traits and 10 inter-simple sequence repeats (ISSR) primers. Principal Component Analysis of morphological data grouped the genotypes into five clusters, with the first two components explaining 61.5% of the total variation. ISSR analysis generated 145 bands, of which 140 were polymorphic and 5 monomorphic. The polymorphism rate in ISSR markers ranged between 86.67% and 100%, demonstrating substantial genetic diversity among the tested genotypes. The discriminatory power of ISSR primers was evaluated using polymorphism information content, with a mean value of 0.39, indicating a moderately high level of informativeness and allelic diversity among populations. In addition, Pearson correlation analysis of morphological traits revealed strong positive associations among floral and foliar parameters (r = 0.70–0.92, p < 0.01), confirming a high degree of morphological integration and developmental coordination within populations. While UPGMA and neighbor-joining dendrograms confirmed the genetic divergence among regional populations, complete regional separation was not observed, possibly due to the dominant nature of ISSR markers. Morphological and genetic data were not always congruent, indicating both environmental influence and underlying genetic variation. This integrated approach provides valuable insights into the genetic structure of S. compacta, for developing effective conservation strategies and guiding the management strategies and sustainable utilization of genetic resources.
