Genetic structure analysis and core germplasm construction of Robinia pseudoacacia and its closely related species based on SNP.
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 1 paper.
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
Robinia pseudoacacia is a forest biomass energy tree species with substantial potential for development and utilization. However, the lack of research on its genetic structure and the unclear genetic background of its germplasm resources impede the conservation and improvement of R. pseudoacacia. In this study, Hyper-seq was used to identify the SNP of Robinia spp. (R. pseudoacacia and its closely related species). The genetic diversity and population structure of 105 Robinia spp. germplasm were analyzed, and a core germplasm bank was constructed. A total of 1,298,097 SNPs and 306,188 InDel polymorphic loci were obtained via mapping with the reference genome. Most of the mutations were detected in the intergenic region. For the 101 R. pseudoacacia samples, the polymorphism information content (PIC) was 0.100 and the nucleotide diversity (Pi) was 0.178, indicating a relatively low level of genetic diversity. Population genetics analysis was conducted based on the 1,312 filtered SNP loci. Phylogenetic relationships divided the entire population into three groups. Genetic structure and cross-validation error indicate low genetic divergence among the sampled individuals. Finally, 21 samples were selected as the core germplasms, accounting for 20% of the total samples. This study provided the basis for genetic research, germplasm protection and breeding of Robinia spp.
