miRNAs targeted transcription factors HaGATAa/b to mediate the post-mating switch in Helicoverpa armigera female reproductive behavior

Abstract

The process of mating induces significant shifts in female reproductive behavior across various species, with the postmating behavioral switch playing a crucial role in insect reproduction. Previous studies have demonstrated the regulatory role of GATA transcription factors in vitellogenin transcription and egg formation in insects, while miRNAs have been implicated in modulating GATA expression and insect reproductive processes. Nevertheless, the precise regulatory mechanism underlying the interaction between miRNAs and GATA transcription factors in the postmating behavioral switch remains largely unexplored.
