Drosophila sex linked traits
WebSexual identity regulates piRNA biogenesis through Sxl, and this effect is mediated, in part, through chromatin proteins Phf7 and Kipferl. Together, our work delineated the genetic control of a sex-specific piRNA program, where sex chromosomes and sexual identity collectively sculpt an essential molecular trait.
