Analysis of piRNAs that participate in the ping-pong amplification loop. a Ping-pong matrices illustrate frequent length-combinations of ping-pong pairs (sequences with 10 bp 5′ overlap). Sequence read length distribution and 1U/10A bias [bits] for ping-pong sequences are shown. b Proposed model of ping-pong amplification in the germline and muscle of C. gigas and L. stagnalis
