Evaluation of tree‐injected oxytetracycline and antisense oligonucleotides targeting <scp>Candidatus</scp> Liberibacter asiaticus in citrus

Citation

Names
Ca. Liberibacter asiaticus
Abstract
AbstractBACKGROUNDHuanglongbing (HLB) is a systemic disease of citrus caused by the bacterial pathogen Candidatus Liberibacter asiaticus (CLas) that limits citrus production worldwide. CLas is an obligate bacterial pathogen that multiplies in citrus trees and in the insect vector, the Asian citrus psyllid (ACP), Diaphorina citri Kuwayama. There is no cure for HLB currently and broad‐spectrum antibiotics represent one possible therapeutic against disease symptoms. Single‐stranded nucleic acid ana

Multiplex Quantitative PCR for the Detection of Bacteria Associated with Huanglongbing ‘Candidatus Liberibacter asiaticus,’ ‘Ca. L. americanus,’ and 16Sr IX Group Phytoplasma

Abstract
The occurrence of ‘Candidatus Liberibacter’ spp. and ‘Ca. Phytoplasma’ spp. associated with blotchy mottle symptoms poses challenges to huanglongbing (HLB) diagnosis using molecular techniques. The ability to detect multiple targets simultaneously and specifically is a key aspect met by quantitative PCR (qPCR). A set of primers and hydrolysis probes useful in either single or multiplex reactions for the detection and quantification of HLB-associated bacteria were developed. Sequences from conse

Judicial Opinion 131

Proteus
Abstract
Opinion 131 addresses a Request for an Opinion asking the Judicial Commission to conserve the genus name Proteus Hauser 1885 (Approved Lists 1980) over its earlier homonym, the protozoan genus name Proteus Müller 1786. The Judicial Commission agrees that the later homonym is illegitimate and that the replacement of the prokaryotic name Proteus would be undesirable. It is also concluded that Proteus Müller 1786 is an objectively invalid name under the International Code of Zoological Nomenclature

Fractionating proteins with nitrite-reducing activity in “Candidatus Kuenenia stuttgartiensis” strain CSTR1

“Kuenenia stuttgartensis” Ca. Kuenenia
Abstract
The anammox bacteria “Candidatus Kuenenia stuttgartiensis” (Ca. Kuenenia) are able to gain energy by combining ammonium and nitrite to produce nitrogen gas, which is an ecologically and technically significant activity process. In this reaction, nitric oxide serves as a recognized intermediate in the reduction of nitrite, which is subsequently combined with ammonium to produce hydrazine. However, the enzyme that converts nitrite to nitric oxide remains elusive. In this study, we investigated the

Complete genome of the mutualistic symbiont “ Candidatus Carsonella ruddii” from a Japanese island strain of the Asian citrus psyllid Diaphorina citri

Citation

Names
Ca. Carsonella ruddii
Abstract
ABSTRACT The complete genome, 173,958 bp in size, of “ Candidatus Carsonella ruddii” DC-OKEB1 , an obligate bacterial endosymbiont of the Asian citrus psyllid Diaphorina citri , was determined. The genome sequence provides valuable information for comparative and evolutionary aspects of the intimate insect–microbe mutualism.

Complete genome of the mutualistic symbiont “ Candidatus Nardonella sp.” Pin-AIST from the black hard weevil Pachyrhynchus infernalis

Ca. Nardonella
Abstract
ABSTRACT The complete genome, 226,287 bps in size, of “ Candidatus Nardonella sp.” Pin-AIST, an obligatory bacterial endosymbiont of the black hard weevil Pachyrhynchus infernalis , was sequenced. The extremely reduced endosymbiont genome is specialized for tyrosine synthesis, which contributes to the hardness of the beetle’s exoskeleton.

Transcriptomic analysis of early stages of ‘Candidatus Liberibacter asiaticus’ infection in susceptible and resistant species after inoculation by Diaphorina citri feeding on young shoots

Ca. Liberibacter asiaticus
Abstract
Huanglongbing (HLB) is a devastating disease of citrus plants caused by the non-culturable phloem-inhabiting bacterium Candidatus Liberibacter ssp., being Ca. Liberibacter asiaticus (CLas) the most aggressive species. CLas is vectored by the psyllid Diaphorina citri and introduced into sieve cells, establishing a successful infection in all Citrus species. Partial or complete resistance has been documented in the distant relatives Murraya paniculata and Bergera koenigii, respectively, providing
