Comparative morpho-anatomical studies of the lesions caused by citrus leprosis virus on sweet orange [PDF]

Anais da Academia Brasileira de Ciências, 2010
The leprosis disease shows a viral etiology and the citrus leprosis virus is considered its etiologic agent. The disease may show two types of cytopatologic symptom caused by two virus: nuclear (CiLV-N) and cytoplasmic (CiLV-C) types.

Methionine Synthase Positively Regulates Plant Defence to Both RNA and DNA Viruses and Is Useful for Developing Broad-Spectrum Antiviral Resistance in Crops. [PDF]

Plant Biotechnol J
ABSTRACT Plant viruses frequently cause severe economic losses in worldwide crop production. Developing broad‐spectrum resistance is the most efficient approach for controlling plant viral diseases. In this work, we found that the 17K protein of barley yellow dwarf viruses (BYDVs), which has multiple functions in viral pathogenesis including acting as ...

History and Diversity of Citrus leprosis virus Recorded in Herbarium Specimens. [PDF]

Phytopathology®, 2015
Leprosis refers to two diseases of citrus that present similar necrotic local lesions, often surrounded by chlorotic haloes on citrus. Two distinct viruses are associated with this disease, one that produces particles primarily in the nucleus of infected

Detection and In Vivo Validation of Dichorhavirus e-Probes in Meta-Transcriptomic Data via Microbe Finder (MiFi^®) Discovers a Novel Host and a Possible New Strain of Orchid Fleck Virus [PDF]

Viruses
Dichorhavirus is a recently accepted plant virus genus within the family Rhabdoviridae. Species assigned to the genus consist of bi-segmented, negative sense, single-stranded RNA viruses and are transmitted by Brevipalpus spp.

Cucumber Green Mottle Mosaic Virus Coat Protein Hijacks Mitochondrial ATPδ to Promote Viral Infection. [PDF]

Mol Plant Pathol
Cucumber green mottle mosaic virus uses the viral coat protein to hijack ATPδ, which in the absence of virus regulates the expression of NbFeSODs to induce superoxide dismutase activity and thus O2− quenching. ABSTRACT The production and scavenging of reactive oxygen species (ROS) are critical for plants to adapt to biotic and abiotic stresses. In this

Rescue of a Cilevirus from infectious cDNA clones [PDF]

Virus Research
Reverse genetics systems represent an important tool for studying the molecular and functional processes of viral infection. Citrus leprosis virus C (CiLV-C) (genus Cilevirus, family Kitaviridae) is the main pathogen responsible for the citrus leprosis ...

Historical and Contemporary Evidence Confirms a Higrevirus as the Causal Agent of Citrus Zonate Chlorosis in Brazil [PDF]

Viruses
Citrus leprosis (CL) and citrus zonate chlorosis (ZC) were first described in Brazil in the 1930s. Both diseases, which caused non-systemic lesions primarily characterized by chlorotic and/or necrotic spots, were associated with the presence of ...

From darkness to light: Genetic manipulation of an atypical plant virus unveils key insights into kitavirus biology, highlighting capsid protein and eIF4A engagement to drive viral infection. [PDF]

PLoS Pathogens
Kitaviridae, a newly recognized virus family, includes plant viruses infecting crops of great global importance, notably citrus. Despite its significant impact on citrus agricultural production, the molecular mechanisms underlying kitavirus infections ...
