Genetic characteristics of endemic Prunus tomentosa in China based on microsatellites.
Article in BMC plant biology, 2025. 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
backgroundPrunus tomentosa Thunb, a fruit tree native to China, is an important and excellent plant material. It exhibits high adaptability to almost all soil types and climatic conditions. The germplasm resources are found in the six geographical regions of China, covering a vast expanse, and comprise a variety of ecological types. However, little is known about genetic diversity and population structure, with its abundant genetic information. Nuclear simple sequence repeat markers, with biparentally inherited characteristics, is powerful for evaluating the genetic diversity of population. Therefore, this research assessed the genetic diversity and population structure of P. tomentosa by collecting extensive samples. The finding will contribute to not only proposing scientific conservation strategies of P. tomentosa but also developing the germplasm to breed novel cherry cultivar.
resultsA total of 822 germplasms from 40 populations were used for assessing. The indicators of genetic diversity showed high values, including observable heterozygosity (0.546), expected heterozygosity (0.819), Shannon's information index (I = 1.951), polymorphism information content (0.799). The populations displaying the greatest diversity-Gan-XlM, Shaan-HM, and Gan-ZhC. In addition, extensive genetic differentiation was detected. The genetic differentiation coefficient (F
conclusionsThe P. tomentosa populations showed high or moderate polymorphism. The genetic differentiation within each population was higher than that between populations. There was a significant correlation between the genetic distance and the geographical distance. Based on genetic diversity and population differentiation levers, the most diverse populations-Gan-XlM, Shaan-HS, and Gan-PL from Gansu and Shaanxi provinces, should first be protected and applied to the innovation of cherry germplasm, followed by significantly differentiated populations, including Chuan-Aba, Ning-HlM, and Gan-PL.
