"Asesino" (vB_EamM_Asesino) is a nucleus-forming phage that infects Erwinia amylovora , representing a unique case that lacks the PhuZ positioning protein found in other nucleus-forming phages. Despite this, the phage successfully replicates using a nucleus-based strategy without active, centrally positioned rotation, as detailed in research published in May 2024.
