Archaeal vesicles: new insights into viral evolution and DNA transfer

点击翻译按钮获取中文摘要

This project aims to determine the basis for plasmid and membrane vesicle generation and DNA transfer at the cellular and molecular level. Recent discovery of plasmid vesicles, which transfer plasmid DNA between host cells using viral capsid-like membrane vesicles, suggests they may be an evolutionary precursor for virus particles. The expected project outcomes include the first substantive characterisation of membrane vesicles in the phylum Euryarchaeota, how plasmid vesicles are generated and transmitted, and new insights into how viruses may evolve. This may lead to new avenues for preventing viral transmission and supporting development of new and improved applications biotechnology and the safe delivery of vaccines or genes in animals and humans.
