Chromosomal DNA content of sweet pepper determined by association of cytogenetic and cytometric tools.
Article in Plant cell reports, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The nuclear DNA content of sweet pepper (Capsicum annuum L. var. annuum, 2n = 24) has been measured by flow and image cytometries but the DNA content of each chromosome of this species has not yet been regarded. DNA content of individual chromosomes has been quantified by the flow karyotyping technique, which requires a great quantity of intact metaphasic chromosomes and methods that allow the characterization of individual chromosomes; however, the obtainment of adequate number of metaphases can be difficult in some species like C. annuum. In order to estimate the DNA content of each C. annuum var. annuum cv. "New Mexican" chromosome, flow and image cytometries were associated with the cytogenetic methodology. First, the DNA amount (2C = 6.90 pg) was established by flow cytometry. Integrated optical density (IOD) values were calculated by image cytometry for each Feulgen stained metaphasic chromosome. Then, by distributing the correspondent metaphasic value (4C = 13.80 pg) proportionally to average IOD values, the following chromosomal DNA contents were obtained in pg: 0.74 (chromosome 1), 0.67 (2), 0.61 (3, 4), 0.60 (5), 0.59 (6, 7), 0.58 (8), 0.57 (9), 0.56 (10) and 0.39 (11, 12). This study reports an alternative and reproducible technique that makes quantifying the chromosomal DNA content possible.
