From: First characterization of PIWI-interacting RNA clusters in a cichlid fish with a B chromosome
Description of piRNA clusters in the B chromosome (named curupira). a–c Depth coverage graphs of piRNA clusters comparing B− (blue) and B+ (red) genomic reads. d–f piRNA cluster characterization. The genomic hits on the top indicate how many times each small RNA was aligned over the genome. Green hits indicate exclusive matches to that genome region. The graphs show the piRNA sequences from the small RNA-seq dataset aligned to piRNA clusters (mapped reads); blue and red regions indicate plus and minus strands, respectively. GS, gene set from genome annotation; RM, RepeatMasker identity. g–i piRNA cluster expression in gonads. The Y axis shows the expression based on the ∆∆Cq method, and the X axis shows the samples. Green asterisks represent significant differential expression (p < 0.0001)
