Convergent Evolution01:54

Convergent Evolution

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while also...
Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
Coronavirus01:29

Coronavirus

Coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV), are enveloped viruses characterized by their single-stranded, positive-sense RNA genome and helical nucleocapsid structure. The hallmark of these viruses is their club-shaped spike (S) glycoproteins that protrude from the viral envelope, facilitating attachment to host cells. Typically, coronaviruses infect the upper respiratory tract, often causing mild or asymptomatic disease. However, certain strains like...
Viral Recombination00:57

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
Viruses of Archaea01:29

Viruses of Archaea

Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Summary

Bats host diverse coronaviruses (CoVs), including those related to SARS. Evolutionary analysis reveals frequent bat CoV host shifts, suggesting potential for future emergence of SARS-like viruses.

Area of Science:

  • Virology
  • Evolutionary Biology
  • Zoonotic Diseases

Background:

  • Bats are recognized reservoirs for numerous coronaviruses (CoVs).
  • Rhinolophid bats carry viruses closely related to the severe acute respiratory syndrome (SARS) coronavirus.

Purpose of the Study:

  • To investigate the evolutionary relationships between bat coronaviruses and their hosts.
  • To understand the mechanisms driving the emergence of zoonotic coronaviruses.

Main Methods:

  • Phylogenetic analysis of viral RNA-dependent RNA polymerase gene sequences.
  • Phylogenetic analysis of bat cytochrome b gene sequences.

Main Results:

  • Identified multiple incongruent phylogenetic associations between rhinolophid bats and their CoVs.
  • Evidence suggests host shifts have occurred in the recent evolutionary history of these viruses.

Conclusions:

  • Bat CoV phylogenies indicate frequent host shifts, possibly driven by viral or host traits.
  • Findings have implications for understanding SARS emergence and the future risk of related viruses.
