General Information
Term transposable element silencing by piRNA-mediated heterochromatin formation ID (Ontology) GO:0141006 (Gene Ontology)
Definition A transposable element silencing mechanism in which a Piwi-associated RNA (piRNA) triggers heterochromatin assembly. Heterochromatin is a chromatin conformation that is refractory to transcription.[ PubMed:32381626 PubMed:32674113 ]
