Genetic diversity and population structure of Tunisian wild Kermes oak (Quercus coccifera L.): Assessment by ISSR molecular markers and implication for conservation.
Article in Molecular biology reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundIn Tunisia, Kermes oak (Quercus coccifera L.) populations are severely destroyed due to deforestation. Nowadays, no preservation programs are attempted, yet, to conserve and promote the potential value of this resource. In this work, we assessed the genetic diversity of seven natural Tunisian populations of Q. coccifera from different bioclimates using Inter-Simple Sequence Repeats molecular markers. The distribution of the genetic diversity of Q. coccifera constitutes the pioneer step in the process of the conservation of the species. METHODS AND
resultsNine selected ISSR markers were analyzed to characterize the genetic profiles of 70 different genotypes. The ISSR primers produced 64 loci ranging from 6 (UBC809 and UBC810) to 9 (UBC873) with an average of 7.11 at the species level. The average percentage of the polymorphic loci varied from 64.06% (Tabarka) to 76.56% (El Haouaria). The analyzed genotypes (70 individuals) revealed a high level of genetic diversity at species level (Na = 1.697; Ne = 1.517; He = 0.289; I = 0.418). The major proportion of the variation was attributable to individual differences within populations (76.07%). Analysis of molecular variance revealed also significant differentiation among all populations (Φ
conclusionsThe in-situ conservation of the species should be maintained on natural populations as a forest genetic resources. Moreover, ex-situ conservation should involve the selection of genotypes with extensive collection of seeds and cuttings from different populations of the target area.
