Evolution of the polyploid north-west Iberian Leucanthemum pluriflorum clan (Compositae, Anthemideae) based on plastid DNA sequence variation and AFLP fingerprinting.
Article in Annals of botany, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
BACKGROUND AND
aimsThe genus Leucanthemum is a species-rich polyploid complex from southern and central Europe, comprising 41 species with ploidy ranging from 2x to 22x. The present contribution aims at reconstructing the evolutionary history of a geographically isolated species group (the L. pluriflorum clan) from the north-west Iberian Peninsula comprising the diploid L. pluriflorum, the tetraploids L. ircutianum subsp. pseudosylvaticum and L. × corunnense (a putative hybrid taxon based on crossing between L. pluriflorum and L. merinoi), and the hexaploids L. sylvaticum and L. merinoi.
methodsChromosome number variation (determined flow cytometrically) and sequence variation were analysed for two intergenic spacer regions on the plastid genome (psbA-trnH and trnC-petN) for individuals from 54 populations in combination with amplified fragment length polymorphism (AFLP) fingerprinting of 246 representative individuals from these populations. KEY
resultsPlastid sequence data revealed that all surveyed members of the L. pluriflorum clan possess plastid haplotypes that are closely related to each other and distinctly separated from other Leucanthemum species. AFLP fingerprinting resulted in allopolyploid fragment patterns for most of the polyploid populations, except for the tetraploid L. × corunnense and a further tetraploid population in northern Galicia, which cluster with the diploids rather than with the other polyploids. In silico modelling of (auto)tetraploid AFLP genotypes further corroborates the allopolyploid nature of L. ircutianum subsp. pseudosylvaticum, L. sylvaticum and L. merinoi.
conclusionsThe present study provides evidence for recognizing one diploid (L. pluriflorum), one autotetraploid (L. corunnense), one allotetraploid (L. pseudosylvaticum) and one allohexaploid (L. sylvaticum with the two geographically and ecologically differentiated subspecies subsp. sylvaticum and subsp. merinoi) in the L. pluriflorum clan. It also has implications for the understanding of biogeographical patterns in the Iberian Peninsula.
