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

backgroundLilium genus consists of approximately 100 species and numerous varieties, many of which are interspecific hybrids, which result in a complicated genetic background. The germplasm identification, genetic relationship analysis, and breeding of Lilium rely on exploiting genetic information among different accessions. Hence, an attempt was made to develop new EST-SSR markers and study the molecular divergence among 65 genotypes of Lilium. METHODS AND

resultsA total of 5509 EST-SSRs were identified from the high-throughput sequencing database of L. 'Elodie'. After primer screening, six primer pairs with the most abundant polymorphic bands were selected from 100 primer pairs. Combined with the other 10 reported SSR primers, a total of 16 pairs detected genetic information with an average PIC value of 0.7583. The number of alleles per locus varied from four to 33, the expected heterozygosity varied from 0.3289 to 0.9231, and the observed heterozygosity varied from 0.2857 to 0.5122. Based on the phylogenic results, 22 Asiatic hybrids (A), seven Longiflorum × Asiatic hybrids (LA), as well as two native species were grouped. Eighteen Oriental hybrids (O) and nine Oriental × Trumpet (OT) hybrids, four native species, one LO, and one LL (L. pardalinum × L. longiflorum) variety were grouped.

conclusionsTwo major clusters were reported and a large number of genotypes were grouped based on UPGMA and STRUCTURE analysis methods. The PIC value as well as other parameters revealed that the EST-SSR markers selected were informative. In addition, the clustering pattern displayed better agreement with the cultivar's pedigree. The newly identified SSRs in this study provides molecular markers for germplasm characterization and genetic diversity for Lilium.
