Although coronaviruses are known to infect various animals by adapting to new hosts, interspecies transmission events are still poorly understood. During a surveillance study from 2005 to 2010, a novel alphacoronavirus, BatCoV HKU10, was detected in two very different bat species, Ro-BatCoV HKU10 in Leschenault's rousettes (Rousettus leschenaulti) (fruit bats in the suborder Megachiroptera) in ...
Analysis of interspecies matings between S. typhimurium and E. coli indicates that the genetic barrier that separates these (and perhaps many other) related species is primarily recombinational. The structural component of this barrier is genomic sequence divergence. The mismatch repair enzymes act as potent inhibitors of interspecies recombination, whereas the SOS system acts as an inducible p...
MOTIVATION Mapping between genotype and phenotype is one of the primary goals of evolutionary genetics but one that has received little attention at the interspecies level. Recent developments in phylogenetics and statistical modelling have typically been used to examine molecular and phenotypic evolution separately. We have used this background to develop phylogenetic substitution models to te...
The lager brewing yeast Saccharomyces pastorianus, an interspecies hybrid of S. eubayanus and S. cerevisiae, ferments maltotriose, maltose, sucrose, glucose and fructose in wort to ethanol and carbon dioxide. Complete and timely conversion ("attenuation") of maltotriose by industrial S. pastorianus strains is a key requirement for process intensification. This study explores a new evolutionary ...
Cell cycle reentry and dedifferentiation of postmitotic cells are important aspects of the ability of an adult newt and other urodele amphibians to regenerate various tissues and appendages [1]. In contrast to their mammalian counterparts, newt A1 myotubes are able to reenter S phase after serum stimulation of a pathway leading to phosphorylation of the retinoblastoma protein, pRb [2]. The acti...
