Mechanisms seeding the emergence of new piRNAs.

Trends in genetics : TIG - 1 Sept 2026

Mitjavila-Ventura Adrià, Vavouri Tanya

Abstract excerpt

PIWI-interacting RNAs (piRNAs) form an adaptive small RNA system that regulates transposons and some host genes in animal gonads. In this forum, we discuss recent within-species comparisons across flies and mammals that reveal extensive variation in piRNA-producing loci, providing new insights into how piRNAs emerge, diversify, and adapt to new threats.
