Mapping 21nt and 24nt reads to the genome shows higher expression of 21nt sequences from some genomic islands while 24nt sequences are evenly distributed throughout the genome. The horizontal bar represents nine unordered papaya chromosomes, the chromosome number denoted by the figure at the left. The black lines represent 21nt reads and the green lines represent 24nt reads.
