Comparative analysis of chloroplast genomes and phylogenetic relationships of different pitaya cultivars.
Article in BMC genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundPitaya is an important tropical fruit highly favoured by consumers owing to its good and juicy characteristics. It contains a large amount of betacyanin, which is a natural food-colouring agent, in the peel and pulp. However, few studies have focused on the pitaya chloroplast (cp) genomes.
resultsTo explore the genetic differences and phylogenetic relationships among the cp genomes of the six pitaya cultivars, we assembled, annotated, and performed a comparative genomic analysis. The cp genomes of the six cultivars exhibited a typical circular structure, ranging in length from 133,146 to 133,617 bp, with a GC content of 36.4%. All individual cp genomes were annotated with 123 genes, including 80 protein-coding genes, 38 tRNA genes, four rRNA genes, and one pseudogene (ycf68). Six mutated hotspot regions (trnF-GAA-rbcL, trnM-CAU-accD, rpl20-psbB, accD, rpl22, ycf1) were detected, which could be considered potential molecular markers for population genetics and molecular phylogeny studies. Phylogenetic analysis showed that pitaya cultivars clustered into a single branch in the phylogenetic tree of the Cactaceae family. Furthermore, the observed phylogenetic patterns suggest a complex genetic basis for colour variation among pitaya cultivars.
conclusionsThe study findings expand our understanding of the cp genome of pitaya and the phylogenetic relationships among different cultivars. The genomic data obtained provide important information for the breeding and genetic improvement of pitaya.
