...). The piRNA pathway presents features of an adaptive defense system against TE invasion (Aravin et al. 2007; Brennecke et al. 2008; Khurana et al. 2011; Yu et al. 2019), but little is known about the processes driving its evolution. Many piRNA pathway genes encoding the proteins involved in TE silencing...

...(Mohn et al. 2014; Shpiz et al. 2014). Because the deletion of large piRNA clusters did not lead to an activation of TEs, it was proposed that these dispersed TEs have an important role in the silencing of TEs (Gebert et al. 2021). The conversion of a regular TE insertion into a piRNA-producing locus...

...). Moreover, an early population genomic analysis of D. melanogaster suggests that TE insertions in piRNA clusters may segregate at higher frequency than noncluster insertions, although this is based on modest sample size and read depth (Lu and Clark 2010).The recent invasion of P-element DNA transposons...

...was shown to play a role in silencing of subtelomeric transposons in Caenorhabditis elegans andDrosophila melanogaster (Fischer et al. 2013;Morgunova et al. 2015). Transposons are targeted by piRNAs in animal germline cells that establish heterochromatin in a similar way to siRNAs in fission yeast (Hirakata...

...and L1 retrotransposons. L1 retrotransposons are repressed in male germ cells by various mechanisms such as the piRNA pathway (Goodier 2016), and MORC2A is highly expressed in testis (Andrews et al. 2016). These data implicate that MORC2A regulates gene and retroelement expression in germ cell lineages...

...of genetic information. In animal germ cells, piRNAs guide PIWI proteins to silence transposable elements (TEs) in order to maintain integrity. In insects, most TE silencing in the germline is achieved by secondary piRNAs that are produced by a feed-forward loop (the pingpong cycle), which requires the piRNA...

.... 2013). This is because the piRNA population in a host rapidly adapts to the TE content through generation of new piRNA clusters, allowing de novo production of piRNA and other types of small RNAs for silencing of the invading TE (Shpiz et al. 2014; Senti et al. 2015). This rapid divergence canbe seen...

The abundance of CHH methylation in plant repetitive elements is typically far less than either CHG or CGmethylation (Feng et al...
