Phylogenomic analysis and development of molecular markers for the determination of twelve plum cultivars (Prunus, Rosaceae).
Article in BMC genomics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundPlums are one of the most important economic crops of the Rosaceae family and are produced all over the world. China has many local varieties, but the genomic information is limited for genetic studies. Here, we first sequenced, assembled, and analyzed the plastomes of twelve plum cultivars and developed molecular markers to distinguish them.
resultsThe twelve plastomes of plum cultivars have a circular structure of 157,863-157,952 bp containing a large single-copy region (LSC) of 86,109-86,287 bp, a small copy region (SSC) of 18,927-19,031 bp, and two inverted repeats (IR) of 26,353-26,387 bp each. The plastomes of plum cultivars encode 131 genes, including 86 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. We detected 50, 54, 54, 53, 53, 50, 54, 54, 54, 49, 50, 54 SSRs in the twelve analyzed varieties, respectively. For repeat sequences, we identified 553 tandem repeats, 204 direct repeats, and 270 palindromic repeats. We also analyzed the expansion/contraction of IR regions. The genes rpl22, rps19, rpl2, ycf1, ndhF, and the trnH span on or near the boundary of IR and single-copy regions. Phylogenetic analysis showed that the twelve cultivars were clustered with the P. salicina and P. domestica. We developed eight markers LZ01 to LZ08 based on whole plastomes and nuclear genes and validated them successfully with six repetitions.
conclusionsThe results obtained here could fill in the blanks of the plastomes of these twelve plum cultivars and provide a wider perspective based on the basis of the plastomes of Prunus to the molecular identification and phylogenetic construction accurately. The analysis from this study provides an important and valuable resource for studying the genetic basis for agronomic and adaptive differentiation of the Prunus species.
