Development of EST-based methylation specific PCR (MSP) markers in Crocus sativus.
Article in Molecular biology reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSaffron (Crocus sativus) is high valued spice crop, but due to its sterile nature, the crop is propagated exclusively through corms. Thus, the genetic base of this crop is very narrow, however, frequency of phenotypic variability is observed; and suggested the potential role of epigenetics in saffron crop growth and development. METHODS AND
resultsTo facilitate epigenetic studies in saffron, we developed 1525 methylation-specific PCR (MSP) markers using MethPrimer. For this purpose, we used 6767 EST sequences of saffron available on the NCBI database. We also mine CpG islands (2555) and found that 32.7% of EST sequences had CpG islands. Out of 1525 MSP markers developed during the present study, 725 covered the CpG islands and 800 were without CpG islands. PCR amplification was found successful for 82% of MSP markers. A preliminary analysis suggested that 53.7% of genomic sites were methylated and more prominent (60% methylations) in non-CpG island regions, although, more comprehensive studies are required to validate it further.
conclusionsThe epigenetic resource developed during the present study will strengthen the epigenetic studies like epiQTL mapping, epiGWAS to explore the molecular mechanisms and genomic/epigenomic regions associated with phenotype; and further may be utilized for saffron improvement programs through epibreeding.
