Characterization of the systems governing sexual and self-recognition in the white rot homobasidiomycete Amylostereum areolatum.

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
This study considered the systems controlling sexual and self-recognition in Amylostereum areolatum, a homobasidiomycetous symbiont of the Sirex woodwasp. To investigate the structure and organization of these systems in A. areolatum, we identified a portion of a putative homologue (RAB1) of the pheromone receptor genes of Schizophyllum commune and Coprinus cinereus, and a portion of a putative homologue of the S. commune mitochondrial intermediate peptidase (mip) gene. Diagnostic DNA-based assays for mating-type were developed and their application confirmed that the fungus has a heterothallic tetrapolar mating system. Segregation analysis showed that RAB1 is linked to mating-type B, while mip is linked to mating-type A. The results of sexual and vegetative compatibility tests suggest that sexual recognition in A. areolatum is controlled by two multiallelic mat loci, while self-recognition is controlled by at least two multiallelic het loci. Therefore, despite the association of A. areolatum with the woodwasp and the unique mixture of sexual and clonal reproduction of the fungus, both recognition systems of the fungus appear to be similar in structure and function to those of other homobasidiomycetes. This is the first report regarding the genes controlling recognition of a homobasidiomycete involved in an obligate mutualistic relationship with an insect.
