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

backgroundZingiberoideae is a large and diverse subfamily of the family Zingiberaceae. Four genera in subfamily Zingiberoideae each possess 50 or more species, including Globba (100), Hedychium (> 80), Kaempferia (50) and Zingiber (150). Despite the agricultural, medicinal and horticultural importance of these species, genomic resources and suitable molecular markers for them are currently sparse.

resultsHere, we have sequenced, assembled and analyzed ten complete chloroplast genomes from nine species of subfamily Zingiberoideae: Globba lancangensis, Globba marantina, Globba multiflora, Globba schomburgkii, Globba schomburgkii var. angustata, Hedychium coccineum, Hedychium neocarneum, Kaempferia rotunda 'Red Leaf', Kaempferia rotunda 'Silver Diamonds' and Zingiber recurvatum. These ten chloroplast genomes (size range 162,630-163,968 bp) possess typical quadripartite structures that consist of a large single copy (LSC, 87,172-88,632 bp), a small single copy (SSC, 15,393-15,917 bp) and a pair of inverted repeats (IRs, 29,673-29,833 bp). The genomes contain 111-113 different genes, including 79 protein coding genes, 28-30 tRNAs and 4 rRNA genes. The dynamics of the genome structures, gene contents, amino acid frequencies, codon usage patterns, RNA editing sites, simple sequence repeats and long repeats exhibit similarities, with slight differences observed among the ten genomes. Further comparative analysis of seventeen related Zingiberoideae species, 12 divergent hotspots are identified. Positive selection is observed in 14 protein coding genes, including accD, ccsA, ndhA, ndhB, psbJ, rbcL, rpl20, rpoC1, rpoC2, rps12, rps18, ycf1, ycf2 and ycf4. Phylogenetic analyses, based on the complete chloroplast-derived single-nucleotide polymorphism data, strongly support that Globba, Hedychium, and Curcuma I + "the Kaempferia clade" consisting of Curcuma II, Kaempferia and Zingiber, form a nested evolutionary relationship in subfamily Zingiberoideae.

conclusionsOur study provides detailed information on ten complete Zingiberoideae chloroplast genomes, representing a valuable resource for future studies that seek to understand the molecular evolutionary dynamics in family Zingiberaceae. The identified divergent hotspots can be used for development of molecular markers for phylogenetic inference and species identification among closely related species within four genera of Globba, Hedychium, Kaempferia and Zingiber in subfamily Zingiberoideae.
