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

Simple sequence repeats (SSRs) are abundant and frequently highly polymorphic in transcribed sequences and widely targeted for marker development in eukaryotes. Sunflower (Helianthus annuus) transcript assemblies were built and mined to identify SSRs and insertions-deletions (INDELs) for marker development, comparative mapping, and other genomics applications in sunflower. We describe the spectrum and frequency of SSRs identified in the sunflower EST database, a catalog of 16,643 EST-SSRs, a collection of 484 EST-SSR and 43 EST-INDEL markers developed from common sunflower ESTs, polymorphisms of the markers among the parents of several intraspecific and interspecific mapping populations, and the transferability of the markers to closely and distantly related species in the Compositae. Of 17,904 unigenes in the transcript assembly, 1,956 (10.9%) harbored one or more SSRs with repeat counts of n > or = 5. EST-SSR markers were 1.6-fold more polymorphic among exotic than elite genotypes and 0.7-fold less polymorphic than non-genic SSR markers. Of 466 EST-SSR or INDEL markers screened for cross-species amplification and polymorphisms, 413 (88.6%) amplified alleles from one or more wild species (H. argophyllus, H. tuberosus, H. anomalus, H. paradoxus, and H. deserticola), whereas 69 (14.8%) amplified alleles from safflower (Carthamus tinctorius) and 67 (14.4%) amplified alleles from lettuce (Lactuca sativa); hence, only a fraction were transferable to distantly related genera in the Compositae, whereas most were transferable to wild relatives of H. annuus. Several thousand additional SSRs were identified in the EST database and supply a wealth of templates for EST-SSR marker development in sunflower.
