Genome dynamics in three different geographical isolates of white spot syndrome virus (WSSV)

Genome dynamics in three different geographical isolates of white spot syndrome virus (WSSV) White spot syndrome virus (WSSV), the sole member of the monotypic family Nimaviridae , is considered an extremely lethal shrimp pathogen.

Abstract

White spot syndrome virus (WSSV), the sole member of the monotypic family Nimaviridae , is considered an extremely lethal shrimp pathogen. Despite its impact, some essential biological characteristics related to WSSV genome dynamics, such as the synonymous codon usage pattern and selection pressure in genes, remain to be elucidated. The results show that compositional limitations and mutational pressure determine the codon usage bias and base composition in WSSV. Furthermore, different forces of selective pressure are acting across various regions of the WSSV genome. Finally, this study points out the possible occurrence of two major recombination events.
