Taxonomy of the order Mononegavirales: update 2016
TLDR
The updated taxonomy of the order Mononegavirales is presented as now accepted by the International Committee on Taxonomy of Viruses (ICTV).
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.
TLDR
Results show that a phytoplasma of group IX is associated with citrus HLB symptoms in northern, central, and southern SPs, transmitted to citrus from an external source of inoculum, but the putative insect vector is not yet known.
Citrus Leprosis Virus Vectored by Brevipalpus phoenicis (Acari: Tenuipalpidae) on Citrus in Brazil
TLDR
This review contains information about the history of the etiology of citrus leprosis, its geographical distribution, host range, the role of the mite vectors, viral morphology and relationships with the infected cell, and transmissibility of the virus by the mites.
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.
TLDR
The new bacterium is a liberibacter and is sufficiently different phylogenetically from known liberibacters to warrant a new species, "Candidatus Liberibacter americanus".
Association of 'Candidatus Liberibacter solanacearum' with a vegetative disorder of celery in Spain and development of a real-time PCR method for its detection.
TLDR
From the results, celery (family Apiaceae) can be listed as a new natural host of this emerging bacterium.
Brevipalpus-Transmitted Plant Virus and Virus-Like Diseases: Cytopathology and Some Recent Cases
TLDR
Virus or virus-like agents are considered to be the causal agents, possibly transmitted in a circulative-propagative manner by Brevipalpus mites, and in some species the ‘cytoplasmic type’ has been found associated with ringspot symptoms.
Novel insights into the genomic basis of citrus canker based on the genome sequences of two strains of Xanthomonas fuscans subsp. aurantifolii
TLDR
umerous commonalities and differences in gene content between the genomes of the pathogenic agents causing citrus canker A, B, and C and other Xanthomonas genomes are uncovered.
