The effector PHYL1JWB from Candidatus Phytoplasma ziziphi induces abnormal floral development by destabilising flower development proteins

Names
Ca. Phytoplasma ziziphi
Abstract
AbstractPhytoplasmas can induce complex and substantial phenotypic changes in their hosts in ways that favour their colonisation, but the mechanisms underlying these changes remain largely unknown. Jujube witches' broom (JWB) disease is a typical phytoplasma disease causing great economic loss in Chinese jujube (Ziziphus jujuba Mill.). Here, we reported an effector, PHYL1JWB from Candidatus Phytoplasma ziziphi, which implicated in inducing abnormal floral organogenesis. Utilising a combination o

Ecological significance of Candidatus ARS69 and Gemmatimonadota in the Arctic glacier foreland ecosystems

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

Mitochondrial Genome Resource of the Cottony Ash Psyllid, a Host of a Newly Identified ‘Candidatus Liberibacter’ Bacterium

Names
“Liberibacter solanacearum” Liberibacter
Abstract
Cottony ash psyllid (CAP, Psyllopsis discrepans) is an important, invasive insect pest of ash trees in North America, where it has established populations and is the host of a newly identified strain of ‘ Candidatus Liberibacter solanacearum’. However, not much is known about the diversity of its introduced population. In this study, a CAP mitochondrial genome (mitogenome) sequence was obtained from a collection in Saskatoon, Saskatchewan, Canada. The CAP mitogenome is a circular DNA of 18,824

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

Citation

Names
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

Citation

Names
“Dehalobacter aromaticus” Dehalobacter alkaniphilus
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
