Fig. 2From: Annotating long intergenic non-coding RNAs under artificial selection during chicken domesticationFunctional annotation of lincRNAs based on adjacent protein-coding genes. a: Overview of distances from lincRNAs to their proximal protein-coding genes within 20Â kb. Red dashed line at about 12Â kb shows the median distance for all flanking protein-coding genes. b: Density of expression correlations between different gene groups by all samples. c: Density of expression correlations between different gene groups by 162 high quality samples. d: Significant categories enriched among protein-coding genes adjacent to lincRNAs within 20Â kbBack to article page
