A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

About

One of the most prominent features of archaea is the extraordinary diversity of their DNA viruses. Many archaeal viruses differ substantially in morphology from bacterial and eukaryotic viruses and represent unique virus families. For instance, viruses with bottle-shaped, lemon-shaped, coil-shaped or droplet-shaped virions are thus far exclusive to the Archaea. The distinct nature of archaeal viruses also extends to the gene composition and architectures of their genomes, and the properties of the proteins that they encode. Environmental research has revealed prominent roles of archaeal viruses in influencing microbial communities in ocean ecosystems, and recent metagenomic studies have uncovered new groups of archaeal viruses that infect extremophiles and mesophiles in diverse habitats. We are exploring the extent of archaeal virus diversity in different habitats and different aspects of their biology, including virion structure and assembly, molecular mechanisms of their entry and egress as well as other aspects of virus-host interaction.
