BLAST alignment of mature miRNAs to two different genomic reference sequences. (a) Size-adjusted Venn diagram indicating that 318 mature miRNAs were aligned to both reference genomes, while 35 and 12 mature miRNAs could only be aligned to K1-P or K1-BB, respectively. (b) The cumulative fraction of BLAST-aligned miRNAs is plotted against the number of perfect genomic matches identified; for each miRNA; 16% and 28% of miRNAs could be perfectly aligned to two or more genomic locations in the K1-P (black) or K1-BB (gray) genomic reference sequence.
