Importance of gene duplication in the evolution of genomic imprinting revealed by molecular evolutionary analysis of the type I MADS-box gene family in Arabidopsis species.

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
The pattern of molecular evolution of imprinted genes is controversial and the entire picture is still to be unveiled. Recently, a relationship between the formation of imprinted genes and gene duplication was reported in genome-wide survey of imprinted genes in Arabidopsis thaliana. Because gene duplications influence the molecular evolution of the duplicated gene family, it is necessary to investigate both the pattern of molecular evolution and the possible relationship between gene duplication and genomic imprinting for a better understanding of evolutionary aspects of imprinted genes. In this study, we investigated the evolutionary changes of type I MADS-box genes that include imprinted genes by using relative species of Arabidopsis thaliana (two subspecies of A. lyrata and three subspecies of A. halleri). A duplicated gene family enables us to compare DNA sequences between imprinted genes and its homologs. We found an increased number of gene duplications within species in clades containing the imprinted genes, further supporting the hypothesis that local gene duplication is one of the driving forces for the formation of imprinted genes. Moreover, data obtained by phylogenetic analysis suggested "rapid evolution" of not only imprinted genes but also its closely related orthologous genes, which implies the effect of gene duplication on molecular evolution of imprinted genes.
