Pigmentation pathway evolution after whole-genome duplication in fish.
Article in Genome biology and evolution, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 71 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
Whole-genome duplications (WGDs) have occurred repeatedly in the vertebrate lineage, but their evolutionary significance for phenotypic evolution remains elusive. Here, we have investigated the impact of the fish-specific genome duplication (FSGD) on the evolution of pigmentation pathways in teleost fishes. Pigmentation and color patterning are among the most diverse traits in teleosts, and their pigmentary system is the most complex of all vertebrate groups. Using a comparative genomic approach including phylogenetic and synteny analyses, the evolution of 128 vertebrate pigmentation genes in five teleost genomes following the FSGD has been reconstructed. We show that pigmentation genes have been preferentially retained in duplicate after the FSGD, so that teleosts have 30% more pigmentation genes compared with tetrapods. This is significantly higher than genome-wide estimates of FSGD gene duplicate retention in teleosts. Large parts of the melanocyte regulatory network have been retained in two copies after the FSGD. Duplicated pigmentation genes follow general evolutionary patterns such as the preservation of protein complex stoichiometries and the overrepresentation of developmental genes among retained duplicates. These results suggest that the FSGD has made an important contribution to the evolution of teleost-specific features of pigmentation, which include novel pigment cell types or the division of existing pigment cell types into distinct subtypes. Furthermore, we have observed species-specific differences in duplicate retention and evolution that might contribute to pigmentary diversity among teleosts.Our study therefore strongly supports the hypothesis that WGDs have promoted the increase of complexity and diversity during vertebrate phenotypic evolution.
