Sharka disease, caused by Plum pox virus (PPV) was first recorded in Bulgaria during the
early twentieth century and since that first report, the disease has progressively spread …

Large heteromeric multiprotein complexes play pivotal roles at every step of gene expression
in eukaryotic cells. Among them, the 20-subunit basal transcription factor TFIID nucleates …

Cells dedicate significant energy to build proteins often organized in multiprotein assemblies
with tightly regulated stoichiometries. As genes encoding subunits assembling in a …

Tobamoviruses are among the best characterized and most studied plant viruses. Three
subgroups of tobamoviruses correspond to viral genome sequence and host range to include …

Three aspects of the infection process of a new tobamovirus species, Hibiscus latent Fort
Pierce virus, recently isolated from hibiscus in Florida, were examined: (i) transmission …

The genetic diversity of plum pox virus strain M (PPV-M) was assessed by analyzing 28
isolates collected in 8 European countries. Two genomic fragments spanning the (Cter)P3-6K1-(…

Most RNA polymerase (Pol) II promoters lack a TATA element, yet nearly all Pol II transcription
requires TATA binding protein (TBP). While the TBP-TATA interaction is critical for …

Sweet cherry is an important fruit crop in Bulgaria. One of the most common viruses of sweet
cherry and other stone fruits in the world is Prune dwarf virus (PDV). Field surveys were …

A novel tobamovirus recently was isolated from hibiscus in Florida. Serological and molecular
methods, including enzyme-linked immunosorbent assay (ELISA), dot-blot immunoassay (…

Malvaceous plants have not been known as hosts for any of the recognized tobamovirus
species until quite recently. Three sub-groups of tobamoviruses have been described that infect …
