A Multicomponent Animal Virus Isolated from Mosquitoes: Cell Host & Microbe - 68 views

  • with each genome segment separately packaged into virions. Although multicomponent genomes are relatively common among RNA viruses that infect plants and fungi, this method of genome organization has not previously been seen in animal viruses (
    • kwedul
       
      Is this the only thing required for a genome to be considered multicomponent?
  • RNA extracted from purified GCXV particles confirmed the presence of a segmented genome (
    • kwedul
       
      So what exactly is it about this purified GCXV that shows it is segmented?
  • The mosquito pools for both ACH27 and TR7094 contained multiple viruses capable of replicating in mosquito cells, so we were unable to obtain pure cultures for these isolates (
    • kwedul
       
      What is it about there being multiple viruses capable of replicating that made them unable to obtain pure cultures for the isolates?
  • ...4 more annotations...
  • Nuclease digestion assays (Figure 1Figure 1B), along with 5′ and 3′ rapid amplification of cDNA ends (RACE), confirmed that all five genome segments were single-stranded, positive-sense RNA (ssRNA+).
    • kwedul
       
      What about these tests confirms all five genome segments were single-stranded positive-sense RNA?
  • all five segments, (2) segments 1–4, and (3) segments 2–5
    • kwedul
       
      Why did they use these three combinations?
  • the number of plaques decreased more quickly than expected with dilution of the inoculant) (
    • kwedul
       
      Why? What is the significance of this?
  • segments 1–5 (passage 1) and segments 1–4 (passage 2)
    • kwedul
       
      What about a second passage, including 1-4, makes it brighter?
