Prevalence in Potato of ‘Candidatus Arsenophonus Phytopathogenicus’ and ‘Candidatus Phytoplasma Solani’ and Their Transmission via Adult Pentastiridius leporinus

Abstract
The planthopper Pentastiridius leporinus (Hempiptera: Cixiidae) is the main vector of two bacterial pathogens: the γ-proteobacterium ‘Candidatus Arsenophonus phytopathogenicus’ and the stolbur phytoplasma ‘Candidatus Phytoplasma solani’. These pathogens cause the disease syndrome basses richesses (SBR) in sugar beet (Beta vulgaris), which reduces the yields and sugar content. In 2022, potato (Solanum tuberosum) fields were found to be colonized by P. leporinus, and the transmission of Arsenophon

Refining the taxonomy of the order Hyphomicrobiales (Rhizobiales) based on whole genome comparisons of over 130 type strains

Rhodoblastaceae
Abstract
The alphaproteobacterial order Hyphomicrobiales consists of 38 families comprising at least 152 validly published genera as of January 2024. The order Hyphomicrobiales was first described in 1957 and underwent important revisions in 2020. However, we show that several inconsistencies in the taxonomy of this order remain and we argue that there is a need for a consistent framework for defining families within the order. We propose a common genome-based framework for defining families within the o

Spatial chemistry of citrus reveals molecules bactericidal toCandidatusLiberibacter asiaticus

Names
Ca. Liberibacter asiaticus
Abstract
AbstractHuanglongbing (HLB), associated with the psyllid-vectored phloem-limited bacterium,CandidatusLiberibacter asiaticus(CLas), is a disease threat to all citrus production worldwide. Currently, there are no sustainable curative or prophylactic treatments available. In this study, we utilized mass spectrometry (MS)-based metabolomics in combination with 3D molecular mapping to visualize complex chemistries within plant tissues to explore how these chemistries changein vivoin HLB-impacted tree

Circular metagenome-assembled genome of Candidatus Patescibacteria recovered from anaerobic digestion sludge

Abstract
ABSTRACT A single-contig, circular metagenome-assembled genome (cMAG) of Candidatus ( Ca. ) Patescibacteria was reconstructed from a mesophilic full-scale food waste treatment plant in Japan. The genome is of small size and lacks fundamental biosynthetic pathways. Taxonomic analysis using the Genome Taxonomy Database revealed that this cMAG belonged to the genus JAEZRQ01 ( Ca

Hiding in plain sight: a widespread native perennial harbors diverse haplotypes of 'Candidatus Liberibacter solanacearum' and its potato psyllid vector

Names
“Liberibacter solanacearum”
Abstract
The unculturable bacterium ‘Candidatus Liberibacter solanacearum’ (CLso) is responsible for a growing number of emerging crop diseases. However, we know little about the diversity and ecology of CLso and its psyllid vectors outside of agricultural systems, which limits our ability to manage crop disease and understand the impacts this pathogen may have on wild plants in natural ecosystems. In North America, CLso is transmitted to crops by the native potato psyllid (Bactericera cockerelli). But

Analysis of huanglongbing-associated RNA-seq data reveals disturbances in biological processes within Citrus spp. triggered by Candidatus Liberibacter asiaticus infection

Names
Ca. Liberibacter asiaticus
Abstract
IntroductionHuanglongbing (HLB), a disease that’s ubiquitous worldwide, wreaks havoc on the citrus industry. The primary culprit of HLB is the gram-negative bacterium Candidatus Liberibacter asiaticus (CLas) that infects the phloem, but its damaging mechanism is yet to be fully understood.Methods and resultsIn this study, a multitude of tools including weighted correlation network analysis (WGCNA), protein-protein interaction (PPI) network analysis and gene expression profiling are employed to u

Updating the unnamed: over 20,000 new Candidatus names for unnamed taxa in GTDB release r214

Abstract
Abstract Here, an established approach to the generation of well-formed arbitrary Latinate names at a scale has been adopted and adapted to name tens of thousands of new, but unnamed taxa within GTDB Release r214.1. New Latinate Candidatus names have been created and assigned to two new archaeal and twelve new bacterial phyla; six new archaeal and 48 new bacterial classes; 13 new archaeal and 158 new bacterial orders; 60 new archaeal and 597 new bacterial families; 271 new archaeal and 3

Putting ‘X’ into context: the diversity of ‘Candidatus Phytoplasma pruni’ strains associated with the induction of X-disease

Abstract
Recurrent epiphytotics of X-disease, caused by ‘Candidatus Phytoplasma pruni’, have inflicted significant losses on commercial cherry and peach production across North America in the last century. During this period, there have been multiple studies reporting different disease phenotypes, and more recently, identifying different strains through sequencing core genes, but the symptoms have not, to date, been linked with genotype. Therefore, in this study we collected and assessed differing disea
