GO:0098026 virus tail, tube
New proposed definition (genus-differentia pattern, plus additional information if needed)
The internal tube of the tail of some viruses. The virus tail tube is the channel for DNA ejection into the host cytoplasm.
Reference(s)
PMID:33188213
Additional information
According to the reference above, not all tailed bacteriophages have contractile tails so I think this should be removed from the definition.
"Tailed bacteriophages—order Caudovirales—comprise the prevailing majority of known phages and are subdivided into three families based on their tail morphology. Podoviridae feature a short tail, Myoviridae a long, contractile tail and Siphoviridae a long noncontractile, flexible tail, respectively"
The comment on the parent term "virus tail" says
Many bacteriophages with dsDNA genomes, or Caudovirales, have a tail. The viral tail can be short (Podoviridae), long and non-contractile (Siphoviridae) or long and contractile (Myoviridae). The tail is the channel through which the phage genome is injected into the host bacterial cell.
