Term Name:	transposable element silencing by piRNA-mediated heterochromatin formation
Synonyms:	piRNA-mediated retrotransposon silencing by heterochromatin formation
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.
