ISSR as new markers for identification of homokaryotic protoclones of Agaricus bisporus.
Article in Current microbiology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
To accelerate the breeding of Agaricus bisporus, quick and reliable methods to identify the infrequent homokaryons are necessary. A new marker, inter simple sequence repeat (ISSR) fingerprinting, is described for differentiation of homo- and hetero-karyotic protoclones. Nine slow growing protoclones, two strandy and seven appressed, were analyzed for the first time with ISSR amplifications. The patterns were highly polymorphic and very reproducible. Among 40 primers tested, 7 ISSR primers were selected for the analysis of genomic DNA and generated a total of 68 ISSR fragments. ISSR fingerprinting detected 44.12% polymorphic loci. All appressed homokaryons carried a subset of ISSR markers found in the heterokaryons, and clustered separately in dendrogram. These were not able to produce a fruiting body. A test of cross-fertility and the following fruiting trial proved that 7 of the 9 protoclones with different ISSR fingerprints were homokaryons. These results demonstrated that ISSR markers provide an efficient alternate for identification of homokaryons and suggest these markers be considered as new tools for the survey of Agaricus species.
