Determinants Of Virus Variation, Evolution, And Host Adaptation, Katherine Latourrette, Hernan Garcia-Ruiz Jan 2022

Determinants Of Virus Variation, Evolution, And Host Adaptation, Katherine Latourrette, Hernan Garcia-Ruiz

Nebraska Center for Virology: Faculty Publications

Virus evolution is the change in the genetic structure of a viral population over time and results in the emergence of new viral variants, strains, and species with novel biological properties, including adaptation to new hosts. There are host, vector, environmental, and viral factors that contribute to virus evolution. To achieve or fine tune compatibility and successfully establish infection, viruses adapt to a particular host species or to a group of species. However, some viruses are better able to adapt to diverse hosts, vectors, and environments. Viruses generate genetic diversity through mutation, reassortment, and recombination. Plant viruses are exposed to …

“When you have an established scientific emergent truth, it is true whether or not you believe in it.” Neil deGrasse Tyson, Science in America. Very few people outside of a particular scientific discipline can actually say they understand it, because most do not have the training to “speak the language.” They are then not particularly bothered by its tenets and predictions. Of all the major branches of science, however, evolutionary biology is an exception to this generalization because even though people are not versed in the field, they sometimes have a negative, knee-jerk objection. This objection is often because they …

A Single Amino Acid Substitution In Soybean Vspα Increases Its Acid Phosphatase Activity Nearly 20-Fold, Oranuch Leelapon, Gautam Sarath, Paul E. Staswick

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Soybean [Glycine max (L.) Merr.] contains two proteins called vegetative storage proteins (VSPs) that function as temporary storage reserves, but are also closely related to plant acid phosphatases of the haloacid dehalogenase (HAD) superfamily. This study examined the biochemical basis for the relatively low catalytic activity previously reported for these VSPs. The specific activity of purified recombinant VSPα on GMP was about 40-fold lower than for a related soybean root nodule acid phosphatase (APase), which had a specific activity of 845 U mg-1 protein. Conversion of Ser106 to Asp increased VSPα activity about 20-fold. This Asp residue …
