 Abstract

Joshua

Extracellular vesicles are produced by organisms across all three domains of life, and play important roles in intercellular communication. While there is a wealth of information regarding their role in parthenogenesis and communication between eukaryotic cells, little is known about their role in environmental systems, communication between microbes, and even less in regards to the archaeal domain. Using the archaeal model organism, Haloferax volcanii, we have uncovered a novel family of proteins that regulate vesiculation that are similar to eukaryotic vesiculating proteins, potentially shedding light on the origins of eukaryotic membrane trafficking. Additionally, exploring the contents of the vesicles hints at a potentially novel mechanism of inter-microbial interaction that could be prevalent in hypersaline systems and beyond.
