Emergency services of viral RNAs: repair and remodeling

VI Agol, AP Gmyl - Microbiology and Molecular Biology Reviews, 2018‏ - journals.asm.org
Reproduction of RNA viruses is typically error-prone due to the infidelity of their replicative
machinery and the usual lack of proofreading mechanisms. The error rates may be close to …

Existing host range mutations constrain further emergence of RNA viruses

L Zhao, M Seth-Pasricha, D Stemate… - Journal of …, 2019‏ - journals.asm.org
ABSTRACT RNA viruses are capable of rapid host shifting, typically due to a point mutation
that confers expanded host range. As additional point mutations are necessary for further …

Robustness to noise in gene expression evolves despite epistatic constraints in a model of gene networks

J Draghi, M Whitlock - Evolution, 2015‏ - academic.oup.com
Stochastic noise in gene expression causes variation in the development of phenotypes,
making such noise a potential target of stabilizing selection. Here, we develop a new …
