Genome size in Anthurium evaluated in the context of karyotypes and phenotypes.
Article in AoB PLANTS, 2012. 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
BACKGROUND AND
aimsAnthurium is an important horticultural crop from the family Araceae, order Alismatales, a lineage considered to have diverged from other monocots prior to the cereals. Genome size and its distribution in Anthurium were investigated to gain a basic understanding of genome organization in this large genus and to forge a firm foundation for advancement of molecular approaches for the study of Anthurium. Currently, genome size estimates have been reported for only two Anthurium samples. METHODOLOGY: Bulk nuclear DNA content estimates were obtained by flow cell cytometry using leaf tissue collected from Anthurium species of different subgeneric groups and from commercial cultivars. The most current and well-supported topology of subgeneric, sectional relationships was applied to present genome size estimates in the context of reported chromosome counts, karyotypes, putative phylogenetic relationships, observed phenotypes and pedigree. PRINCIPAL
resultsGenome size estimates based on bulk nuclear DNA content for 77 accessions representing 34 species and 9 cultivars were obtained, including initial estimates for 33 Anthurium species, and both the smallest (Anthurium obtusum; Tetraspermium) and largest (Anthurium roseospadix; Calomystrium) Anthurium genome sizes reported to date. Genome size did not distinguish any subgeneric section, but ranged 5-fold (4.42-20.83 pg/2 C) despite consistent 2N= 30 chromosome counts. Intraspecies genome size variation >20 % is reported for Anthurium ravenii, A. watermaliense and A. gracile.
conclusionsGenome size estimates for Anthurium species spanning 13 recognized subgeneric sections indicate that genome size does not generally correlate with chromosome count or phylogenetic relationships. Mechanisms of genome expansion and contraction, including amplification and reduction of repetitive elements, polyploidy, chromosome reorganization/loss, may be involved in genome evolution in Anthurium as in other species. The new information on Anthurium genome sizes provides a platform for molecular studies supporting further research on genome evolution as well as cultivar development.
