Assembly and comparative analysis of the complete mitochondrial genome of the spice plant Cinnamomum longepaniculatum.
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 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
backgroundCinnamomum longepaniculatum(Gamble) N. Chao ex H. W. Li (C. longepaniculatum), a species renowned for its leaves and twigs yielding essential oils, is extensively utilized as a vital raw material in traditional Chinese medicine, spice, and daily chemical products, and thus possesses both high economic value and significant scientific research value. However, to date, no detailed information on the mitochondrial genome (mitogenome) has been reported.
resultsThe mitogenome of C. longepaniculatum was characterized by a linear structure, spanning 870,686 bp with 46.94% GC content. It encompassed 44 protein-coding genes (PCGs), 28 tRNAs, and 3 rRNAs. Numerous repetitive sequences were observed, including 317 simple sequence repeats (SSRs), 52 tandem repeats and 874 pairs of dispersed repeats. Phylogenetic analysis based on the 41 conserved mitochondrial PCGs of C. longepaniculatum reflected its close evolutionary affinity to C. camphora, followed by C. chekiangense and C. insularimontanum. Furthermore, dot-plot analysis revealed diverse homologous collinear regions between C. longepaniculatum and other species belonging to the Laurales. Specifically, the largest collinear blocks, spanning over 861 kb, accounted for 95.59% of the total proportion between C. longepaniculatum and Cinnamomum camphora, indicating a high degree of conservation and similarity in their mitogenome structures.
conclusionsThis study presents the initial assembly and annotation of C. longepaniculatum mitogenome, thereby enriching the limited repository of mitogenome sequences available for Laurales plants. These findings provide crucial molecular evidence for further studies on the evolutionary relationships and genomic evolution within the Laurales.
