Classification of tospoviruses based on phylogeny of nucleoprotein gene sequences.
The nucleotide sequences of the nucleoprotein (N) genes of seven tospovirus isolates representing three serogroups were determined and used to establish phylogenetic parameters to delineate species within the Tospovirus genus of the Bunyaviridae. A high sequence divergence (55.9% identity at the nucleotide level) was observed between isolates of serogroup I (tomato spotted wilt virus) and isola...
متن کاملA natural M RNA reassortant arising from two species of plant- and insect-infecting bunyaviruses and comparison of its sequence and biological properties to parental species.
Reassortment allows multicomponent viruses to exchange genome segments, a process well-documented in the vertebrate- and arthropod-infecting members of the family Bunyaviridae but not between distinct species of the plant- and insect-infecting members of the genus Tospovirus. Genome sequence comparisons of a virus causing severe tospovirus-like symptoms in Florida tomato with Groundnut ringspot...
متن کاملIn Vivo Localization of Iris yellow spot Tospovirus (Bunyaviridae)-Encoded Proteins and Identification of Interacting Regions of Nucleocapsid and Movement Proteins
BACKGROUND Localization and interaction studies of viral proteins provide important information about their replication in their host plants. Tospoviruses (Family Bunyaviridae) are economically important viruses affecting numerous field and horticultural crops. Iris yellow spot virus (IYSV), one of the tospoviruses, has recently emerged as an important viral pathogen of Allium spp. in many part...
متن کاملSequence analysis of ORF94 in different White Spot Syndrome Virus (WSSV) isolates of Iran
White spot syndrome virus (WSSV) is a pathogen that causes high mortality in shrimp culture in the whole world. Sequence analysis of WSSV has shown similarity of WSSV isolates in different countries with exception of a few variable genomic loci. This study investigated the sequence variation of some Iranian WSSV isolates and previously identified isolates. Samples were collected during target ...
متن کاملNucleoprotein (NP) Gene Based Phylogenetic Analysis of Iranian H9N2 Avian Influenza Isolates during 1998-2011
Background and Aims: Avian Influenza (AI) H9N2 subtype was first reported to infect turkeys in the United States in 1966 and has been panzootic in Eurasia. In Iran, the H9N2 virus was first isolated from broiler chickens in 1998 in Ghazvin province and it is the most prevalent subtype of influenza virus in poultry industry in Iran at the present time. Materials and Methods: In this study, we se...
