'Candidatus Megaira' are diverse symbionts of algae and ciliates with the potential for defensive symbiosis

Names

Abstract
Symbiotic microbes from the genus 'Candidatus Megaira' ( Rickettsiales ) are known to be common associates of algae and ciliates. However, genomic resources for these bacteria are scarce, limiting our understanding of their diversity and biology. We therefore utilize Sequence Read Archive and metagenomic assemblies to explore the diversity of this genus. We successfully extract four draft 'Ca. Megaira' genomes

Effects of reducing, stabilizing, and antibiotic agents on “Candidatus Kuenenia stuttgartiensis”

Abstract
Abstract Anaerobic ammon ium oxidizing (anammox) bacteria oxidize ammonium and reduce nitrite, producing N2, and could play a major role in energy-optimized wastewater treatment. However, sensitivity to various environmental conditions and slow growth currently hinder their wide application. Here, we attempted to determine online the effect of environmental stresses on anammox bacteria by using an overnight batch activity test with whole cells, in which anammox a

Foliar Antibiotic Treatment Reduces Candidatus Liberibacter asiaticus Acquisition by the Asian Citrus Psyllid, Diaphorina citri (Hemiptera: Liviidae), but Does not Reduce Tree Infection Rate

Names
Ca. Liberibacter asiaticus
Abstract
Abstract Huanglongbing (HLB), or citrus greening, is the most destructive disease of cultivated citrus worldwide. Candidatus Liberibacter asiaticus (CLas), the putative causal agent of HLB, is transmitted by the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae). In Florida, D. citri was first reported in 1998, and CLas was confirmed in 2005. Management of HLB relies on the use of insecticides to reduce vector populations. In 2016, antibiotics were approved to m

Control of Candidatus Liberibacter asiaticus vector with plant extracts and biorational products in Mexican lime

Names
Ca. Liberibacter asiaticus
Abstract
In Mexico, Huanglongbing HLB has become endemic in all Mexican lime producing areas. This disease is transmitted by the insect Diaphorina citri (Hemiptera: Liviidae). The objective of the study was to evaluate different plant extracts and biorational products for the control of D. citri in mexican lime. Two evaluations were made under field conditions; the first one included five treatments, with previous sampling and at 8, 20 and 27 days after the application of the treatments. In the second, e

Genetic diversity of Candidatus Liberibacter asiaticus strains from the Central Pacific citrus region in Mexico

Abstract
Huanglongbing (HLB) is associated with Candidatus Liberibacter asiaticus (CLas). It is a destructive disease of citrus. The objective of this study was to determine the genetic diversity of 90 strains of CLas infecting eight citrus species trees from the Central Pacific in Mexico. Genetic diversity among CLas was estimated by fourteen variable numbers of tandem repeat (VNTRs) loci. Three loci were polymorphic, SSR00 and SSR077 amplified four alleles each, while the locus SSR-A amplified two alle

Identification of the Actin-Binding Region and Binding to Host Plant Apple Actin of Immunodominant Transmembrane Protein of ‘Candidatus Phytoplasma mali’

Ca. Phytoplasma mali
Abstract
‘Candidatus Phytoplasma mali’ (‘Ca. P. mali’) has only one major membrane protein, the immunodominant membrane protein (Imp), which is regarded as being close to the ancestor of all phytoplasma immunodominant membrane proteins. Imp binds to actin and possibly facilitates its movement in the plant or insect host cells. However, protein sequences of Imp are quite diverse among phytoplasma species, thus resulting in difficulties in identifying conserved domains across species. In this work, we comp
