Strain-Specific Protein Interaction And Localization Of Two Strains Of Potato Yellow Dwarf Virus And Functional Domains Of Their Matrix Protein, Chanyong Jang
Theses and Dissertations--Plant Pathology
Potato yellow dwarf virus (PYDV) is the type species of the genus nucleorhabdovirus which is typified by its nucleotropic characters of the members. The virus accomplishes its replication and morphogenesis in the nuclei of infected cells. Two strains, Constricta strain (CYDV) and Sanguinolenta strain (SYDV) have been described at the level of vector-specificity. CYDV is vectored by Agallia constricta and SYDV is transmitted by Aceratagllia sanguinolenta. The full-length genome of CYDV was sequenced. The 12,792 nt antisense genome encodes seven open reading frames in the order of, nucleocapsid protein (N), unknown protein (X), phosphoprotein (P), movement protein (Y), matrix …

Systemic acquired resistance (SAR) is a form of inducible defense response triggered upon localized infection that confers broad-spectrum disease resistance against secondary infections. Several factors are known to regulate SAR and these include phenolic phytohormone salicylic acid (SA), phosphorylated sugar glycerol-3-phosphate (G3P), and dicarboxylic acid azelaic acid (AzA). This study evaluated a role for free radicals nitric oxide (NO) and reactive oxygen species (ROS) in SAR. Normal accumulation of both NO and ROS was required for normal SAR and mutations preventing NO/ROS accumulation and/or biosynthesis compromised SAR. A role for NO and ROS was further established using pharmacological approaches. Notably, …
