1 · What the graph read from it

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.

2 · The registry

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

backgroundThe sea aster, Tripolium pannonicum (Jacq.) Dobrocz 1962, the sole species of the genus Tripolium, is an annual halophyte. Native to estuarine and coastal marsh ecosystems, it plays a vital ecological role in maintaining the stability of saline habitats and supports biodiversity. In addition, it holds significant economic value as a biomass resource. Despite its ecological and economic importance, genomic data for T. pannonicum have been lacking. Here, we report the first complete chloroplast genome of T. pannonicum, providing a foundational resource for phylogenetic and ecological studies of halophytic species within the Asteraceae family.

resultsThe assembled chloroplast genome has a total length of 153,075 bp and a GC content of 37.2%. It comprises four distinct subregions: a large single copy (LSC) region of 84,385 bp, a small single copy (SSC) region of 18,028 bp, and two inverted repeats (IRs) of 25,331 bp each. The chloroplast genome encodes 127 genes, including 88 protein-coding genes (PCGs), 34 transfer RNA genes, and 8 ribosomal RNA genes. Phylogenomic analysis using the whole PCGs revealed that the chloroplast genome of T. pannonicum is closely related to members of the genus Aster.

conclusionsThis study provides the first chloroplast genome for the genus Tripolium, addressing a significant gap in genomic data for halophytic members of the Asteraceae. The results enhance our understanding of the phylogenetic placement and evolutionary relationships of T. pannonicum within the tribe Astereae. Beyond taxonomy, the chloroplast genome offers a molecular foundation for species identification, biogeographic research, and the genomic approach for the estimation of population structure. These data are especially relevant in providing molecular tools that can be applied to ecological monitoring and conservation strategies for salt-tolerant plant species threatened by habitat degradation and climate change.
