DNA polymerases have an innate error rate which is polymerase and DNA context specific. Historically the mutational rate and profiles have been measured using a variety of methods, each with their own technical limitations. Here we used the unique properties of single molecule sequencing to evaluate the mutational rate and profiles of six DNA polymerases at the sequence level. In addition to accurately determining mutations in double strands, single molecule sequencing also captures direction specific transversions and transitions through the analysis of heteroduplexes. Not only did the error rates vary, but also the direction specific transitions differed among polymerases. Copyright © 2016 Elsevier B.V. All rights reserved.
Complete genome sequence of pseudorabies virus reference strain NIA3 using single-molecule real-time sequencing.
Pseudorabies virus (PRV) is the causative agent of Aujeszky’s disease in pigs. PRV strains are also used as model organisms for the study of alphaherpesvirus biology or for neuronal pathway studies. We present here the complete genome of the virulent wild-type PRV reference strain NIA3, determined by single-molecule real-time sequencing. Copyright © 2016 Mathijs et al.
