Impact of coat protein on evolution of ilarviruses.

The genomic sequences attributed to the coat protein play a pivotal role in the evolutionary trajectory of plant viruses. The coat protein region, particularly scrutinized in the genus of Ilarvirus phylogroups, actively shapes the regional and host-specific dispersion. Within this chapter, assorted insights pertaining to the roles undertaken by coat proteins of frequently encountered Ilarviruses in their evolutionary processes are consolidated.

Revealing an Iranian Isolate of Tomato Brown Rugose Fruit Virus: Complete Genome Analysis and Mechanical Transmission.

An analysis of the complete genome sequence of a novel isolate of tomato brown rugose fruit virus (ToBRFV) obtained from tomatoes in Iran and named ToBRFV-Ir is presented in this study. Comprehensive phylogenetic analysis utilizing key viral proteins, including 126 KDa, 183 KDa, movement protein (MP), and coat protein (CP), as well as the complete genome sequence, classified ToBRFV-Ir and 65 isolates from GenBank into three distinct clades. Notably, genetic diversity assessment revealed relatively low variability among the isolates, irrespective of their geographical or clade affiliation.

First complete sequences and genetic variation of plum pox virus T strain in and .

Unlabelled: The complete genome of plum pox virus strain T isolates from five different spp., including almond (. ) and sour cherry (.

Genetic Variation between Asian and Mediterranean Populations of Cucurbit Aphid-Borne Yellows Virus.

Viral symptoms, such as yellowing, leaf deformation, mottling, vein clearing, and reduced yield, were observed in cucurbits in Iran. This study aimed to detect the main suspected causal agent, cucurbit aphid-borne yellows virus (CABYV), in Iran and analyze the genetic diversity among isolates. Two hundred samples were collected from different growing areas between 2019 and 2022.

Global Population Structure of Apple Mosaic Virus (ApMV, Genus ).

The gene sequence data for apple mosaic virus (ApMV) in NCBI GenBank were analyzed to determine the phylogeny and population structure of the virus at a global level. The phylogenies of the movement protein (MP) and coat protein (CP) genes, encoded by RNA3, were shown to be identical and consisted of three lineages but did not closely correlate with those of P1 and P2, suggesting the presence of recombinant isolates. Recombination Detection Program (RDP v.

Molecular Analysis of the Global Population of Potato Virus S Redefines Its Phylogeny, and Has Crop Biosecurity Implications.

In 2020, 264 samples were collected from potato fields in the Turkish provinces of Bolu, Afyon, Kayseri and Niğde. RT-PCR tests, with primers which amplified its coat protein (CP), detected potato virus S (PVS) in 35 samples. Complete CP sequences were obtained from 14 samples.

Insight into Population Structure and Evolutionary Analysis of the Emerging Tomato Brown Rugose Fruit Virus.

A total of 112 symptomatic tomatoes ( L.) and 83 symptomatic pepper ( spp.) samples were collected in Ankara, Eskişehir, Bartın, and Zonguldak provinces of Turkey during 2020-2021.

Phylogenetic and diversity analyses revealed that leek yellow stripe virus population consists of three types: S, L, and N.

Phylogenetic and evolutionary analyses were performed on the P1 and CP genes of global isolates to clarify the phylogrouping of leek yellow stripe virus (LYSV, genus Potyvirus), a pathogen affecting Allium spp. worldwide, into different types based on genetic variation and host species. The constructed phylogenetic trees divided the isolates into three major groups: S, L, and N.

Prunus necrotic ringspot virus in Turkey: an immigrant population.

An outbreak in northwestern Turkey of prunus necrotic ringspot virus (PNRSV, genus Ilarvirus, family Bromoviridae) was sampled in 2016-2018. Gene sequences from these isolates, together with all of the gene sequence data for this virus in the GenBank database (>300 non-recombinant coat protein (CP) genes and 20 complete genomic sequences) were analysed to determine the relationship of the Turkish PNRSV isolates to those from other parts of the world. Phylogenetic and population genetic methods independently showed that the most recent common ancestor of the world PNRSV population was probably American, not Eurasian.
