Abstract
Abstract  The Gemmatimonadota phylum has been widely detected in diverse natural environments, yet their specific ecological roles in many habitats remain poorly investigated. Similarly, the Candidatus ARS69 phylum has been identified only in a few habitats, and literature on their metabolic functions is relatively scarce. In the present study, we investigated the ecological significance of phyla Ca. ARS69 and Gemmatimonadota in the Arctic glacier foreland (GF) e

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

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

Testing low‐risk bioactive compounds on Halyomorpha halys: an improved pipeline of analyses to investigate their effects on the bacterial endosymbiont Candidatus Pantoea carbekii

Abstract
AbstractBACKGROUNDThe brown marmorated stink bug Halyomorpha halys has become an invasive insect pest of many crops. A promising control strategy to manage the proliferation of H. halys is based on the suppression of its obligate and vertically transmitted uncultivated symbiotic bacterium Candidatus Pantoea carbekii through surface‐sterilization of H. halys eggs. Indeed, the application of antimicrobial formulations on the eggs of H. halys could cause mortality of endosymbiont and consequently o

Detection and Multigene Characterization of ‘Candidatus Phytoplasma ulmi’ Strains Infecting Ulmus spp. in Southern Italy

Ca. Phytoplasma ulmi
Abstract
‘Candidatus Phytoplasma ulmi’ (16SrV-A) is the causal agent of elm yellows (EY), a lethal and/or decline disease of several Ulmus (elm) species and hybrids in North America and Europe. In this study, field observations and PCR assays were used to detect phytoplasma infections in diseased U. minor, U. pumila and U. glabra trees in southern Italy. Also, a multigene sequence analysis employing various less conserved genes was carried out to explore the genetic variation in detected strains. All the

Pangenomic insights into Dehalobacter evolution and acquisition of functional genes for bioremediation

Abstract
Dehalobacter is a genus of organohalide-respiring bacteria that is recognized for its fastidious growth using reductive dehalogenases (RDases). In the SC05 culture, however, a Dehalobacter population also mineralizes dichloromethane (DCM) produced by chloroform dechlorination using the mec cassette, just downstream of its active RDase. A closed genome of this DCM-mineralizing lineage has previously evaded assembly. Here, we present the genomes of two novel Dehalobacter strains

Proposal of Patescibacterium danicum gen. Nov., sp. nov. in the ubiquitous ultrasmall bacterial phylum Patescibacteriota phyl. Nov

Abstract
Abstract Candidatus Patescibacteria is a diverse bacterial phylum that is notable for members with ultrasmall cell size, reduced genomes, limited metabolic capabilities and dependence on other prokaryotic hosts. Despite the prevalence of the name Ca. Patescibacteria in the scientific literature, it is not officially recognized under the International Code of Nomenclature of Prokaryotes (ICNP) and lacks a nomenclatural type. Here, we rectify this situation by describing two closely

Occurrence of a ‘CandidatusPhytoplasma pruni’-Related Strain Associated with Commercial Poinsettias in Turkey

Abstract
AbstractThe poinsettia (Euphorbia pulcherrimaWilld. ex Klotzsch.) is one of Turkey’s most important potted ornamental crops. Potted poinsettia plants exhibiting smaller-sized brilliant red bracts against the green leaves with free-branching were collected from commercial florists in three provinces of Turkey. In iPhyClassifier analysis, the query 16SrDNA sequences of our isolates shared 99.58% identity with that of theCandidatusPhytoplasma pruni. Our leaf samples consistently yielded a product o
