A phytoplasma closely related to the pigeon pea witches'-broom phytoplasma (16Sr IX) is associated with citrus huanglongbing symptoms in the state of São Paulo, Brazil.
In February 2007, sweet orange trees with characteristic symptoms of huanglongbing (HLB) were encountered in a region of São Paulo state (SPs) hitherto free of HLB. These trees tested negative forExpand
Taxonomy of the order Mononegavirales: update 2016
In 2016, the order Mononegavirales was emended through the addition of two new families (Mymonaviridae and Sunviridae), the elevation of the paramyxoviral subfamily Pneumovirinae to family statusExpand
Citrus Leprosis Virus Vectored by Brevipalpus phoenicis (Acari: Tenuipalpidae) on Citrus in Brazil
Citrus leprosis is caused by Citrus leprosis virus (CiLV) that is transmitted by mites in the genus Brevipalpus (Acari: Tenuipalpidae). This disease directly reduces production and the life span ofExpand
Association of 'Candidatus Liberibacter solanacearum' with a vegetative disorder of celery in Spain and development of a real-time PCR method for its detection.
A new symptomatology was observed in celery (Apium graveolens) in Villena, Spain in 2008. Symptomatology included an abnormal amount of shoots per plant and curled stems. These vegetative disordersExpand
First Report of a Huanglongbing-Like Disease of Citrus in Sao Paulo State, Brazil and Association of a New Liberibacter Species, "Candidatus Liberibacter americanus", with the Disease.
Huanglongbing (HLB) (ex-greening) is one of the most serious diseases of citrus. The causal agent is a noncultured, sieve tube-restricted α-proteobacterium, "Candidatus Liberibacter africanus" inExpand
A new eriophyid mite-borne membrane-enveloped virus-like complex isolated from plants.
A decade ago, a new mite-transmitted disease was described on wheat (Triticum aesativum) and maize (Zea mays) that due to its geographical location was referred to as High Plains Disease (HPD). ToExpand
Brevipalpus-Transmitted Plant Virus and Virus-Like Diseases: Cytopathology and Some Recent Cases
An increasing number of diseases transmitted by Brevipalpus mite species (Acari: Tenuipalpidae) is being identified that affect economically important plants such as citrus, coffee, passion fruit,Expand
The nonstructural protein (NSs) encoded by the ambisense S RNA segment of tomato spotted wilt virus is associated with fibrous structures in infected plant cells.
The open reading frame located in the viral strand of the ambisense S RNA of tomato spotted wilt virus (TSWV), was cloned into transfer vector pAc33DZ1 and inserted downstream of the polyhedrinExpand
Citrus Leprosis: Centennial of an Unusual Mite-Virus Pathosystem.
Novel insights into the genomic basis of citrus canker based on the genome sequences of two strains of Xanthomonas fuscans subsp. aurantifolii
BackgroundCitrus canker is a disease that has severe economic impact on the citrus industry worldwide. There are three types of canker, called A, B, and C. The three types have different phenotypesExpand
